Hi
I have 3 robots and I know the starts and end coordinate of each of them. For example for Robot 1 I have Xr1, Yr1 and Xr2,Yr2 coordinates pair , same for Robot2 and 3. I have lateral cameras so can obtain the visual information. I would like to get the robot-to-robot relative position over time. The camera update is every 0.5 seconds. How can I approach this problem and any possible solution? Is the Hidden Markov Model chains would be a good approach? OR semantic Mapping can be helpful?

I am interested in the use and purpose of social robots. What do you think are the benefits and goals of making robots "social".
  • There is an obvious goal of trying to increase acceptance.
  • I personally believe that social agency can help robots accomplish social tasks, such as persuasion.
  • "Social" behavior can also motivate humans to interact more intuitively with the robot, e.g. via speech commands.
Can you think of other goals and benefits that I might have missed?
Best,
Patrick
Relevant answer
Answer
Is the question about benefits in a narrow sense of economic gain, or in the larger sense of serving human well-being? If it is meant in the latter sense, then the "non-replacement principle "of ISR (Integrative Social Robotics) can offer a heuristics to identfy beneficial applications: "social robots may only do what humans should but cannot do".

We know that robot pose errors are very common and that robot trajectories are pre-constructed and generated from CAD models in machining scenarios. However, for the trajectory points, there are inherent errors, and we need to compensate for the position and attitude of these trajectory points.
The existing off-line compensation is very common, but it lacks real-time, and the compensation objects are all the results obtained from pre-experiments. In fact such compensation, in a new experiment, the whole process is different from that of the pre-experiment because of the compensation done, so the final compensation also all stay at the level of being able to improve the performance, and theoretically such compensation is also all incomplete.
How to compensate for the new point errors based on the information obtained in real time, and update the point information of the generated trajectory in real time?

Relevant answer
Answer
You have asked a very good question, usually the tuning process is not mentioned a lot in the literature pushing it under the carpet by mentioning " trial and error " although this is true somehow but this requires a lot of experience from the practitioner. I would suggest two solutions depending on my previous work, you can start with placing the poles that would ensure the stability of the system by pole placement to determine the gains and thus u = -kx (state feedback control) and by this you would gain some intuition about the values of the gains when you want to use the PID later on. Another method is to use Model free controller (intelligent PID), when using this method, you can start with any reasonable choice of PID controller gains and then you are left to tune only one parameter (alpha). This controller is simple and sometimes resolve the problem of having to tune manually the PID controller.

Sensors have played a significant role in intelligent robots and autonomous driving. While lidars and cameras have become dominant in the field, the advancements of other sensors have also promoted its developments.
MMWR is becoming promising. Its 4D imaging technology is becoming more and more mature. Even though I am not familiar with this kind of sensor and have no experience with it, as a person working in robotic and autonomous systems, I am interested in it. I hope this message can reach someone who knows about it.
Questions are:
1. How about the role of 4D MMWR in robots and autonomous vehicles, especially compared with lidar and cameras? or even replace them as primary sensors?
2. Is 4D MMWR robust enough for L3 or above-level autonomous driving?
3. Are there any other fields that 4D MMWR will be applied more often or promising?

Hi,
I want to train a model for real time robot, I have a set of videos, want to train model for action recognition and model will be fed to robot to identify human actions. I never worked before for on video data. How should I start?
Relevant answer
Answer
Just so that I understand your setup correctly could you let me know the operating system being used? The reason is that all peripheral devices are controlled by the operating system kernel.
For example in Linux (which is what I use) I can communicate directly with the OS video interface (V4L) and do a program in C that extracts the frame in YUV format
An example of the C program is:
note that in the function init_device the resolution is set along with the format
fmt.fmt.pix.width = 640; fmt.fmt.pix.height = 480; fmt.fmt.pix.pixelformat = V4L2_PIX_FMT_YUYV;
With this properties and the read_frame function allows you to extract the particular frame and the process_image sends it to standard output. Instead of sending it to standard output you would need to send it to a function that converts the YUV signal to the required format for processing by your routines. The function will have to convert each of the values of YUV for the resolution specified to RGB in values from 0-255. the conversion in your function would need to do a translation to RGB using the formulas in:
Once you do this you will have a buffer that is 640*480*3 (the values above times the the R, the G, and the V values). If you just want greyscale array that is 640*480 you can use:
Grayscale = (R + G + B ) / 3.
then you will just have a buffer that is 640*480
At this point you can then use the frame for processing by the ML or you can resize it to the appropriate resolution.
This is just to give you the general idea. The same steps will have to be done in Python and whether it is Windows or Linux.
Note that some libraries will manage this process and convert them to AVI or MP4. Due to your real time constraints I would suggest that you do not waste processing time converting them and then decode them and waste time parsing the format structure.

Answer
This short illustrated past-present-futurist article looks at ten facets of robotics for agriculture:
"Top 14 Agricultural Robots For Harvesting And Nursery
April 10, 2019/ ByBaiju NT-
📷
"The world population is expected to hit 9 billion by 2050. What is expected to follow is a dramatic increase in agricultural production, doubling to meet future demand. This need made farmers turn to robotics as a solution for the future.
Many in the agricultural sector agree that the industry is heading towards more technology on the farm, which could include agricultural robots. Indeed, several companies have already made significant progress in creating robotic systems for use in agriculture that are either in field testing stages or already entering the market.
In this post, we will look at a list of top 14 agricultural robots for nursery and harvesting.
1.Harvest Automation HV-100
Harvest Automation HV-100 is a farmer’s assistant designed to work alongside people, planting. Although designed to work in a variety of manual positions, moving potted plants around works well in nurseries. It can do an enormous task of moving potted plants from point A to point B. With experience using simple mapping software to allow robots to perform tasks autonomously in a known environment, Harvest robots can work around the clock without vacation or time off.
2. Energid Citrus Picking System
Energid Citrus Picking System is ideal for the citrus fruit business. It can select fruit every 2 – 3 seconds. The robot is not only cheap, but also very efficient.
3. Agrobot E-Series
Designed for strawberry fields, Agrobot E – Series has twenty – four robotic wireless arms that can not only quickly pick strawberries, but can also identify a strawberry’s maturity in the field.
4. Robotic Vacuum Apple Picker – Abundant Robotics
Thanks to Abundant Robotics, apple orchard farmers can now use robots instead of seasonal pickers. AR startup uses vacuum to select apples from trees. The robot uses algorithms to identify and locate apples in the tree. Technology not specifically designed for agriculture. In a wide range of industries, the same technology can be applied, but for now they use it in agriculture. The robot is designed to accurately harvest and store apples. The collection is made through a flexible hose and storage is made in the same big boxes that human workers use.
5. Harvey – Capsicum Harvester
The Technology University of Queensland developed a prototype robotic capsicum (sweet pepper) harvester nicknamed’ Harvey,’ combining robotic vision and automation expertise to benefit farmers. The camera system and harvesting tool are mounted at a standard robotic (arm) manipulator end. Combining robotic-vision techniques and crop manipulation tools are key factors in harvesting these crops.
6. Sweeper
Sweeper, backed by the EU as part of its Horizon 2020 innovation program, is built to pick ripe peppers in a greenhouse. To do his job, Sweeper uses a camera that recognizes a pepper’s color. Computer vision then helps the robot decide whether to pick the fruit. If so, Sweeper uses a small razor to cut the stem before catching the fruit in its “claws” and dropping it in a basket below.
7. Green Robot Machinery
This is a cotton-picking robot, developed by Green Robot Machinery. The robot is programmed for typical cotton topography. For maximum motion range, the robot uses six degrees of freedom to reach the cotton plant from the side. Using path-planning algorithms, the arm is guided to the cotton. The robot creates the plant’s 3D model and, using a vacuum tube, the machine sucks the cotton in a more time-efficient manner.
8. FFRobotics
FFRobotics is a robot that collects 10,000 apples an hour. FFRobotics machine has a three-fingered grip that can grab and twist fruit from a branch and has at least twelve robotic arms. Like many other robots, FFrobot uses advanced algorithms and algorithms to pick tree fruits. Image processing algorithms can detect fruits damaged, diseased, or unripe. The grasping hand can be easily modified to pick different fruit types. This makes the robot available for various harvest seasons.
9. GRoW
MetoMotion’s GRoW is described as ‘a multipurpose robotic intensive system for labor-intensive tasks in greenhouses with the ability to harvest tomatoes.
10. Dogtooth – Harvesting Soft Fruits
Strawberries are delicate fruits requiring careful picking. Start-up Dogtooth Technologies designed a robotic arm capable of harvesting sensitive fruits like strawberries. Using machine vision and motion planning algorithms, the robot recognizes and locates the ripe fruit to be picked. The next robot development step is to improve learning algorithms.
To make better fruit harvesting decisions, the robot needs learning algorithms to harvest with fewer errors. Several cameras capture the fruit images for a detailed view of the crops. The GPS system mounted on the robot platform helps precise plant and fruit production. Thus, the farmer can identify the most productive area and low-yield area.
11. Energid Citrus Picking System
This large but low – cost orange – picking gadget can clear an orange tree as little or less as human labor would cost. That means picking an orange every two to three seconds, sounding slow, but this robot never gets tired.
12. MIT Robot Gardener
Massachusetts Institute of Technology students designed a mobile robot to maintain soil moisture and pick ripe fruit. A network of sensors attached to each plant monitor soil humidity and call the water robot. The robot communicates wirelessly with the sensor.
13. Agrobot SW6010
Agrobot SW6010 is a tractor-like robot. This machine uses sensors and robotic arms to detect and pick ripe berries with alarming speed and efficiency. Sensors on the robotic arms can actually tell which berries are ripe and not based on the unpicked berry’s shape and size. It packs them in boxes!
14. Cucumber Harvester
Cucumber Harvester is a smart robot that can spot and pick ripe cucumbers on the vine. In 1996, research began on the development of an autonomous cucumber harvesting robot supported by the Dutch Ministry of Agriculture, Food and Fisheries. The robot detects individual cucumbers, assesses maturity and harvests ripe cucumbers. The project was completed in 2002."

A quadruped robot has four legs. Each legs has 3 degrees of freedom i.e 3 joints. But the quadruped robot can also move with 2 joints on each leg. What are the disadvantages of using 2 joints instead of 3 .
Relevant answer
Answer
Quadruped Robots feature four legs or limbs and walk like quadruped animals. They are more agile and stable than bipedal robots. They are widely categorized into two types based on their leg structure: Mammal-type and Sprawling-type.
Legged robots are a form of mobile robot that moves by using movable limbs, such as leg mechanics. They are more adaptable than wheeled robots and can traverse a wide range of terrains, but these benefits come at the expense of higher complexity and power consumption.
A quadruped robot is capable of walking with both statically and dynamically stable gaits. Each leg of the robot is pulled up and down sequentially in the statically stable gait, and there are at least three stance legs at any one time. This is referred to as a crawling gait.

Dear helper,
I am currently busy with a project for autonomous driving of tractor semi-trailers with of axle hitching. I want to design an input-output linearizing feedback for a non-linear MIMO system. I am getting stuck on how to do so. I want to know how I can decouple my system, and how to model it in Simulink to let my tractor semi-trailer track a desired output. I hope you can help me with this. My system looks as follows:
x2dot = v*(cos(gamma)*cos(theta2) - (L1b/L1)*tan(delta)*sin(gamma)*cos(theta2))
y2dot = v*(cos(gamma)*sin(theta2) - (L1b/L1)*tan(delta)*sin(gamma)*sin(theta2))
theta2dot = (v/L2)*((L1b/L1)*tan(delta)*cos(gamma) + sin(gamma))
gammadot = v*((1/L1) - (L1b/(L1*L2))*cos(gamma))*tan(delta)) - (v/L1)*sin(gamma)
The inputs are the velocity u1 = v, and the steering angle u2 = delta. For the output I choose the articulation angle y1 = gamma between the tractor, and semi-trailer. To take an additional output to have the amount of inputs, and outputs equal I suppose to take as an additional output y2 = y. To give an idea on how the system looks like, I have added a picture of my system. My system is written for the coordinates of the rear axle of the semi-trailer, and has therefroe, the indice 2.
I know how to treat certain problems for non linear MIMO systems but I don't understand how to do this case due to the 2 inputs influencing each other. The system is not well defined if one of the inputs equals zero.

Hi all,
Presently I am starting the venture of writing my master's thesis. The subject of my thesis concerns the implementation of robotic process automation (RPA) software in organisations. I'd like to look at critical success factors in different stages of the implementation process. To ultimately deliver a scientifically grounded and validated framework on how to conduct successful RPA implementation projects. To do so, I will be conducting qualitative research.
However I could use some help with it from our community as I am presently struggling with finding an appropriate theoretical lens to apply in my thesis.
Therefore I am looking for suggestions for possible lenses to use which can be used in qualitative research. I have come across theories such as diffusion-of-innovation (DOI), technology acceptance model (TAM) and unified theory of acceptance and use of technology (UTAUT). These however have a quantitative nature and thereby seem less appropriate.
To summarize, I am looking for a theoretical lens to study RPA implementation projects which can be used in qualitative research, do you have any suggestions on which lens to use? It may also be more broad or sociological lenses rather than strictly technological lenses.
Please let me know, your help and advice is highly appreciated!

The problem is when I set the starting angle in State Target>Position and update my model it looks fine , but when I try to connect a sine wave in order to control the joint movement, I noticed that the arm is no longer started from the angle I have set recently.
Any advice will be highly appreciated.

Do you know any special sources to learn ... ?
Relevant answer
Answer
Dear Amirreza
If I understand your question well known, there are six three-linear, three-circular compounds, and there are several rates that can calculate a degrees of freedom like a well-known classical equation
ddl=6n-5(P5)-4(P4)-3(P3)-2(P2)-(P1)
N Number of moving elements
Pi and i =1,.....,5 : Number of joints
P1 class one means have 5 dof
P2 class tow have 4 dof
P3 class three have 3 degrees of freedom
P4 class four have 2 dof
P5 classe five have 1 dof
And can you see this site for more information about another method

Im trying to get Velocity in order to control underwater swarm ROV. I can use the acceleration and to Euler integration but the error will be accumulated over time. As we are having a swarm (many small robots) Im limited with sensors on board. So in order to get more accurate Velocity estimation was thinking of sensor Fusing of IMU and odometry. As don't have any odometry sensors came to some out of the box solution.
So as I have access to the motor (thruster- propeller) signals and the robot can move to maximum and constant speed. Means the rotation of the propeller have a maximum limit and when they reach that limit they can maintain that maximum. So was thinking of some mathematical model that can be used to provide me with odometry and than use some of the ROS packages for sensor fission(robot_lokalization or hector_pose_estimation) to get accurate Velocity
So I need a help in that mathematical model how to get odometry from the motors-thrusters. Any help with that and possible ROS node (C++) implementation?
Thanks

Dear Dr. Dariuscz Prokopowicz,
I consider that the type of scientific research that dominates in the field of "intelligent production" revolves around theoretical discussions about the existence of "intelligent territories", generating in turn a concept that has been developed recently, taking as bases the notions of:
a) "Knowledge Society"
b) "Knowledge Economy"
c) "Sustainable Development"
d) "Social Inclusion".
These are new types of territorial spaces in which we interact for the sake of a new advance in the Economy and thinking about the New Social Structures that are being generated after Covid-19 with new behaviors of Human Beings.

Hi
I have IMU sensor that gives me the raw data such as orientation, Angular and Linear acceleration. Im using ROS and doing some Gazebo UUV simulation. Furthermore, I want to get linear velocity from the raw IMU data. If I do integration over time there will be accumulated error and will not be accurate with the time when for example the robot makes turns.
So If I use
acceleration_x = (msg->linear_acceleration.x + 9.81 * sin(pitch)) * cos(pitch); acceleration_y = (msg->linear_acceleration.y - 9.81 * sin(roll)) * cos(roll);
So integrating linear acceleration is very bad,
Velocity_x= Velocity_old_x+acceleration_x*dt;
because integrates the acceleration without taking into account any possible rotation of the sensor, which means that the results will probably be terrible if the sensor rotates at all.
So I need some ROS package that takes into account all this transformation and gives me the most accurate estimation of the linear velocity. Any Help? Thanks

Didactic methods based on computer games are included in the new education 4.0. Therefore, education systems should be improved in such a way as to make the most of the techniques known for the current technological progress known as Industry 4.0.
On the other hand, as part of the technological revolution of Industry 4.0, other technologies are also being developed that should be effectively implemented into modern education tools so that education systems can be improved and adapted to new technologies that are currently being dynamically developed and implemented in industry. In addition, these new technologies Industry 4.0 should also enrich the work of scientists in research laboratories of universities and schools. Scientific research conducted in the field of new technologies, innovations, etc. should also be correlated with Industry 4.0.
Apparently, we are now living in the era of the fourth technological revolution, known as Industry 4.0.
The previous three technological revolutions:
1. The industrial revolution of the eighteenth and nineteenth centuries, determined mainly by the industrial application of the invention of a steam engine.
2. Electricity era of the late nineteenth century and early twentieth century.
3. The IT revolution of the second half of the twentieth century determined by computerization, the widespread use of the Internet and the beginning of the development of robotization.
The current fourth technological revelation, known as Industry 4.0, is motivated by the development of the following factors:
- artificial intelligence,
- cloud computing,
- machine learning,
- Big Data database technologies,
- Internet of Things.
On the basis of the development of these IT instruments and technologies, business analytics of companies such as Business Intelligence and the above-mentioned areas have been dynamically developing in recent years.
The technological revolution described as Industry 4.0 is progressing more and more dynamically. The reforms in the school system should follow this progress, so that modern education 4.0 would be fully adapted and correlated with the progress of Industry 4.0.
The technological revolution Industry 4.0 is carried out so quickly that education systems and fields of study, teaching methods are adapted to these changes often with a significant delay.
On the other hand, research conducted in research centers at universities should support the creation of new innovations in technological solutions for the needs of industry 4.0.
Therefore, the education system should be improved in such a way as to create as much synergy and correlation as possible between the current technological revolution of Industry 4.0 and the reformed systems of new education 4.0.
One of these areas of new teaching techniques are the above-mentioned computer games. In many training centers, for example in the field of training pilots, drivers, cosmonauts, aircraft controllers, etc., simulators that technologically use modern computer games are used. Computer games should therefore be used in the process of improving didactic techniques in education systems 4.0.
Therefore, I am asking you with the following query: Can computer games be used in the process of improving teaching techniques in 4.0 education systems?
Please, answer, comments. I invite you to the discussion.
Relevant answer
Answer
Yes, the computer games should be used in the education systems.

I observed several models that are trained on teaching robots to do grasping tasks, and I noticed that the success rate varies within 7 % in each training session. Also, it can be noted that the validation of each model's training session may have an impact on the performance. It implies that it is neither steady nor efficient. That's why the Deep-RL model's training might take several sessions to find the optimal learning. Also, if we take those several training sessions and put them to the test in various scenarios, we can see that the success rate varies.
  • Is the RL-framework impacted by image preprocessing, or is it because the RL is fighting to find the best policy, which may not guarantee proficiency and stability in each learning session?
Relevant answer
Answer
Well, data and its preprocessing have an impact on the performance. However, as you mentioned, it depends on the network to find the best policy. Note that you should make sure you have observed the requirements, including
1. Enough epochs of training; otherwise the results may even vary widely, depending on the severity.
2. Dependence on the initial seeds and randomness; this certainly has an impact, such that not only in RL but also in other kind of ML it affects results.
3. Using final weights, not intermediate weights

Hi everyone,
I am currently writing my master thesis about customer acceptance of service robots. I use SPSS Process model 9 (moderated mediation).
My IV is robot's voice type (human vs. robotic), mediator is robot's perceived credibility and DV is customer's service encounter evaluation. The a-path from IV to M is moderated by robot's appearance (humanlike vs. machinelike) and customer's extraversion.
In my model, I take different control variables/ covariates into account which are interesting in robotic research. I look at participant's age and gender and if they have had previous interaction with a robot to check if those variables have an influence on my DV. Age and gender seem to have no influence, but robot interaction does.
However, I also collected data on the participant's nationality/country of origin. Taking this variable into the model I have some interesting results, such as that German participants rated the service a lot lower than other nationalities.
Now my problem is, that my Independent variable voice type becomes slightly insignificant when I add nationality/country as a covariate (of course dummy coded). Before adding country the voice style’s p-value was 0,0598 and with the nationality/country, it is at p=0,1007 ( I am using a p-value of <0.1).
My second concern is, that my nationalities are not evenly distributed. I have 501 participants in total and 259 germans (51,7%) and the second-highest is the USA (49 people, 9,8%), Taiwan (8%), the Netherlands (6,4%), UK (4%), Franke (3,2%) and other countries (17%).
So I am wondering if my results can be representative if more than half of the respondent’s nationalities are germans? Therefore, I was wondering if it would be recommend to take nationality into account as a control variable or if I should leave it out, because then also the c' path from voice type to service encounter evaluation would remain significant at p= 0,0598.
Thank you for your help! Best, Nina

funny I had read the tweet two. One problem with a drawing a complete DAG however is that you have to come up with a complex structure among the surrounding variables (i.e., the control candidate). I find this rather challenging and the library probably won't tell you. That's why I thought creating a kind of flowchart of critical decisions would be of some help. I did not find an example of a structure where the steps lead to an error.
The most obvious goal is to prevent controlling for mediators, colliders/selection factors, and instrument (or not recognizing the potential of a variable as an instrument.
What do you think?
All the best

They say the best educators are able to make a complex subject easily understood by a child. Perhaps this is a challenge to us all.
Quarternion mathematics can be quite complex to wrap your head around. For educators out there how are you explaining this to your students from high school.
Is a pictorial method the most appropriate under these circumstances.
Relevant answer
Answer
Hey Joseph,
In my opinion sticking with unit quaternions would be the way to go. At a high school level it may be a good idea to skip the complex math definitions and instead focus on the intuitive "definition" of a unit axis and a rotation about that axis. Depending on the context you could run through an animation/example in 2D or 3D to show how multiplication works, then give the multiplication rules as formulas -- the same way one might do for dot and cross products at the high school level.
I would guess another important question to answer is why a roboticist would use quaternions instead of other representation. Having a short discussion on gimbal lock could be a great motivator, especially if there audience is interested in aerospace applications or robotic arms.
Thanks,
Logan

It may be referred an "EngD" because it is product oriented and 75% of the time I dedicate it on a company, doing the study and development of a robot (in my case). I feel it is quite different from a PhD because there are decisions that are not always science related but market or profit related, which is also good to learn.
But within my colleagues I am the only one and the rest are real PhD researches, and it is hard for me to justify certain research approach.
Does any of you feel the same? Should I push to state in my presentations that my research is a EngD position or not?

Answer
In my understanding , the degree " Eng.D" is in fact the degree " PhD" in the field of industry and applied sciences. An EngD degree is essentially an engineering PhD with a solid industrial base and an additional taught element. The distinction between them is that the Doctor of Engineering degree is designed for practitioners who wish to apply the knowledge they gain in a business or technical environment.The PhD is highly focused on developing theoretical knowledge, while the EngD emphasizes applied research.
