Agricultural Robotics - Science topic

Dear user, I'm Johnny Waked, a Ph.D. student at the University of Sassari, Department of Agriculture. My research activity concerns the study and implementation of land-based agricultural robots to support farmers' activities. The study in which I ask you to participate involves the analysis of the factors that could influence your intention to use land-based agricultural robots also known as Unmanned Ground Vehicles (UGV). These vehicles, in fact, could support the farmer's activities in field and crop management (soil tillage, phytosanitary treatments, fertilization, etc.). To this end, we ask you to participate in the survey by answering questions, lasting 7 minutes, which you can access from the following link: https://forms.gle/XQavw3CAdESM8f2T7 #management #research #university #phd #agriculture #robots

Considering a four wheel skid steering heavy robot of one ton, I need to know the minimum torque needed to rotate itself from standstill.

Are the calculous very easy or there is a paper that is exhaustively focused on this issue?

In my opinion, the wheels torque should be greater than (i.e. win) the static friction considering that all four wheels are not rotating. Indeed the robot should move normal to its longitudinal axe which in our case coincides with the longitudinal axes of the wheels.

Other than the impact of an agricultural environment on the static friction, what is the impact of the wheel orientation?

What is the impact of the center of gravity in case it does not coincide with the center of area?

Thank you very much

Is one of the products of the integration of Information Technology Industry 4.0 will be the creation of fully autonomous robots capable of self-improvement?

Is the combination of artificial intelligence and technology learning machines, robotics, the Internet of Things and data processing in the cloud and Big Data databases automatically acquiring information from the Internet and possibly other advanced information technologies typical of the current technological revolution Industry 4.0 will allow to create fully autonomous robots capable of self-improvement?

I am designing an autonomous visual navigation system in an agriculture robot. From the farm, I got some images of the lane and now I am unable to get proper from those images. Until now, I tried many methods of image processing to detect the lanes but nothing works. I also used holistically-nested edge detection (HED) on the images but did not get the output as desired. I need suggestions that how I can detect the lanes from these images.

Currently, the field is in the Seed Sowing stage, so it is more difficult to differentiate the lanes in the field. I am attaching a sample of the lane, please give me some suggestions.

The first image is the original image, the second image is the edited one to show the lanes in the field, and the third one is formed after the canny edge detection.

Thank you

I have a robotic system that is not actuated in one joint (no torque is applied) and actuated in all other joints.

In this model, the blue rectangles are the links of the robot, the filled small circles are the joints and the circle slot is a constraint that the slider is rotating around it. The red filled circle and the red slot are connected to the ground but the red filled circle is a motor that produces torque. Among other joints, 2 of them are actuated and one is just a joint and isn't actuated.

The slider is applying force to the circular slot to remain on the track. This constraint force consists of a force toward the center of the slot and a moment in the direction perpendicular to the figure.

I want to solve the forward dynamics (by having the joint torques, I want to obtain all link's angular accelerations) to convert it into a state-space form. It is preferable for me to be able to obtain the constraint forces in the slider, also. I don't want to use ordinary newton's method. What other methods do you recommend me to use and why? Please remember that this system is a closed-lop kinematic chain and not a tree-structure (serial kinematic structure). I will be grateful if you introduce good references for the method you recommend.

Thanks

Can someone provide me with information on how to control a physical robot arm with V-Rep?

I am new to robotics and I want to link my V-Rep simulation to a real KUKA arm

In some activities it is possible and robots are already produced, which replace people in specific repetitive activities.

However, will robots replace people in future in all activities and functions?

In my opinion, it is not possible for this type of futurological vision to be realized.

People are afraid of such a scenario of the future development of civilization.

The expression of these fears is the predominance of negative futurological visions known from fictional literature and films that such a development of civilization in which autonomous robots replace people in almost all activities, difficult work, production processes and achieve a high level of artificial intelligence generates serious threats to humanity.

Without bees and other pollinating insects, most species of terrestrial flora and fauna will soon disappear and there will be a serious problem with feeding people on Earth.

For several years, the phenomenon of massive extinction of whole bee swarms in some regions of the world, including mainly regions of crop cultivation, has been observed.

Therefore, when this unfavorable process will continue, perhaps in the future the solution to this problem will be the creation of a Smart Robo-Bee, ie nanotechnological, miniaturized artificial robotic insects.

These Smart Robo-Bees could pollinate flowers of cereals, vegetables, shrubs, fruit trees, etc. in the situation of complete extinction of pollinating insects.

Is this a realistic scenario to solve the problem of extinction pollinating insects?

Please, answer, comments.

consider an agriculture robot which can work according to the given image. The robot should differentiate the weeds in the picture which we have given and it has to remove that weeds in the field. 

I am writing a review paper on way point tracking of articulated arm manipulator. Can anyone suggest me a good study material or research paper on the same?

i want to calculate the position of a object which in-belted with acclerometer and gyroscope and magnetometer so i want a accurate position of an object with less accuracy (eg: less than 0.5 cm(error)), i just tried in internet to find solution but i found everything is old accelerometer and gyroscope i couldn't find anything less than 1 cm of error accuracy (accelerometer).

We have designed a autonomous robotic systems for agricultural pesticides applications. Currently I am acquiring the sensors data through wired lines. I want to switch this system in wireless mode. Meaning is that, I want to operate in wireless mode, i.e. want to acquire multisensors data through wireless. Can anybody suggest me suitable wireless module for the mentioned purposes. 

Thanking you!

I am writing a book on biosensors for agrifood sector and I am looking for a researcher working on the use of drones for biosensor/sensor application in precision farming.

I do not fully understand what base inertial parameters means? What are they used for? I'm carrying out an inverse kinematics and direct dynamics of a 4 dof. articulated robot. Is there helpful advose in this case?

Which method should I follow, numerical or symbolic?

The question might be apparently simple, but I could not google a single satisfactory answer. I would like to develop a device for picking a number of small stones from the ground without human bend.
