Re: V-REP and AI

Hello, You have different possibilities to do that: Have your program interface and call the remote API shared library (in that case, your language has to support native C calls). Or you can write a List/Scheme binding for the remote API Have your program use the ROS interface (not sure if ROS is su...

Re: Maximum area supported

Hello Antonio, There is no specific limitation in size. However: Dynamic objects will only be active in a specific radius, counting from the origin. Refer to the variable "dynamicActivityRange" in file "system/usrset.txt" to adjust this radius You can use very large maps. Make su...

Re: What is the unit of mass?

Hello,

Yes, it is kilograms.

The API functions are all in international system of units (SI). Meaning meters, kg, seconds, etc.
The user interface units can be adjusted, except for the masses. That might come in a future release.

Cheers

Re: Problem with Set Inertial Matrix dialog

Hello, This is a known issue with Kubuntu. We currently support and test Windows, MacOS and Ubuntu platforms. It is virtually impossible to test and adjust all the various Linux distributions for us. If you have some experience, could you try to compile v_rep and see if you can solve the problem? We...

Re: Adjustable shape reference frame

Hello,

If you require another reference frame, you can always attach a dummy to the shape, then make calculations relative to the dummy. Having another local reference frame for the shape object would add more confusion I guess.

Re: Joint coming apart

Hello Nikolaus, I see two potential causes for that to happen: 1. The links are overlapping and colliding. Make sure they do not overlap or that they have their respondable masks set correctly. 2. The links have too small masses, or a too small moment of inertia. Or the proportion between masses inv...

Re: Viscous damping and static friction for joints possible?

Hello,

For that, you will have to approximate things with a PID controller for now. Otherwise, if you can wait around 2 weeks, there will be a new V-REP release (3.0.2) where you will be able to write custom joint controllers.

Re: Communication Delay ROS V-REP

Hello again, The best thing that you could do it to artificially limit the frequency of your control algorithm on the controller side when testing the virtual quadrotor. And have also the quadrotor send synchronization signals to V-REP, so that you can run the simulation step-by-step. It will of cou...

Re: Communication Delay ROS V-REP

If you turn display off, and have a very light simulation content, then you can have less than 1ms for a simulation pass.

But I still don't understand what kind of task V-REP will have in there. Could you explain a bit further?

Cheers
