Questions related to Robotics
Based on a critical look at the rate at which technology is advancing, especially AI, VR, AR, IoTs, robotics etc and their application in education; advancement in personalized learning and Education 4.0, and the fast approaching 4IR, would educators at all levels of education still be relevant in the almost-here-future?
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'm doing a scoping review in the field of robotics and neurosurgery but with a specific topic. I chose scoping review to assess the gap of knowledge on the topic being investigated.
After doing the search (PubMed, EMBASE, and Scopus) and assessing according to inclusion and exclusion criteria I finished with only 3 articles. Can I continue writing my paper or three articles are insufficient to make a scoping review?

How to formulate 2D frames if I have the origin of the frames (x, y) and the inclination angle of the frame with respect to the x-axis? Then I need to compute the transformation matrix of the frames w.r.t the reference frame (which is normal x and y directions)??
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?
I know I should be using the concept of Dead Reckoning. But how do I use prediction algorithms to determine/estimate the 2D coordinates and yaw angle, if I can get the gyroscope data, wheel encoder data, and global system time or timestamp of each input?
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？

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.
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?

people often complain of robots and artificial intelligence taking the jobs of men. i was just wondering if the world really needs such technology. why does one need a machine to think like a human to do a task instead of just getting a person to perform that task?
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.
I have a path that want to located in robot workspace

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!
Recently, we have heard about collaborative robots and human friendly robots for use in industry. We have seen some applications, but with no real co-working activities (for security reasons).
Do you have real examples of human/robot collaboration in industry? What could be a good application for the future?
I am working on a tensegrity robotic fish which is made of 5 variable stiffness tensegrity joints (VSTJs) in series. In the initial design as you can see in the diagram there is a spring connecting the base to follower on both sides. Now to develop a control system I am changing these springs to flexible bodies actuated by SMA wires with flexible sensors attached. I can model the robot in Solidworks and import the CAD to simscape.
Question: How can I model the flexible sensor and SMA wires in simscape to develop a dynamic model?
Dear academicians/researchers , I am trying to simulate a sinusoidal wave for my robot arm. 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.

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?

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,
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
I am trying to validate my serial dilution protocol using a robotic pipettor. We will be doing the serial dilution in 100% DMSO. I have tried using fluorescein to ensure my protocol has good CV% and linearity, but I quickly learned that DMSO quenches fluorescein signal. Since I am just using this to validate my protocol, I don't need any particular binding, just something that isn't quenched by DMSO. Thank you!

I am looking for a Robotic Process Automation tool that I can use in a class on process automation. I am using the Camunda WfMS for implementing a workflow and would like to add a session on RPA. It should be easy to learn so that we can use it as part of a case study assignment.
Has anybody got experience with such tools and a recommendation for a corresponding system?
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.
Why we do not consider the potential and kinetic energy of the motor at the joints in the two arm robot..I see only considered the links in the Lagrange equation .However the motor at the joint has height same as link has height this mean has potential energy also when the first link rotate the body of the motor will rotate to gather with second link which produce kinetic energy
Robotization is clearly accelerating its pace. Does it have the potential to bring immediate unemployment? What are its advantages for Human Resources?
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?

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
I am working on mobile robots formation control. I have some issues in choosing linear and angular velocities for the leader robot and follower robots. The results are changing for different velocity parameters. I would like to know, How to choose Linear velocity and Angular Velocities for mobile robots in leader-follower-based formation control methods?
I was recently advised it might be predatory and I struggle to decide whether I should still choose to publish with them, keeping in mind I am at the debut of my PhD and it would be problematic to start my research career by publishing with a controversial journal.
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.
I am searching for providers of robotic platforms for high throughput screening of polymorphs. We need to be able to dispense both solids (powders) and liquids, ideally on 12 x 8 well-plates.
For the moment I have found only two companies which provide such platforms: Unchained Labs and Chemspeed. I have spent a big amount of time searching on google with different keywords, but whatever comes are in the best case just robots for dispensing liquids, and not both liquids and solids as we need.
It would be totally awesome if some of you could share the name of more companies which actually produce such robotic platforms, because I cannot believe that there are only the aformentioned two on the market!
Thanks a lot and stay healthy!
In recent years, many articles have appeared, assessing the risks of automating the economy in the next 10-20 years due to the development of unmanned technologies.
But there are also counterfactual assessments from labor market experts who believe that scientific progress always creates more jobs than it kills in the long run.
Who is right?
I am currently enrolled in a "PhD" but here it is called "industrial doctorate program".
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?
