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.

Cheers

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?

Re: Textures and light

Oh, it might be another reason, not really sure since I can't regognize much in the picture: If your object is composed by very large triangles, then local lighting might not be taken into account: openGl calculates the lighting on a triangle by interpolating the lighting at its corners. If the corn...

Re: Shaking Robot

Hello Felipe,

Make sure you read this section of the user manual. It is very important regarding the dynamics of a simulation. In particular all the "design considerations".

Re: Textures and light

Hello Arnaud,

Yes, you can do that. In the texture dialog, just click "modulate colors". The texture will then be modulated with the shape color, and be influenced by lighting.

Re: Communication Delay ROS V-REP

Hello Fiete, It is important to understand that V-REP will not produce more data than the speed of the simulation loop. If the simulation loop takes 5ms, then publishers will only update data every 5 ms. It wouldn't make sense to update the same data more than that anyway, since it would stay same. ...

Re: Texture dialog

Hello, I am not sure I understand your problem exactly. This is what you should do: 1. Import your obj file by specifying "Preserve texture coordinates" 2. Select the imported shape, then open the shape dialog , and click "Adjust texture". 3. Make sure you can read "Associat...

Re: simx_GetSimulationTime

Hello,

Have a look at simxGetLastCmdTime.

Alternatively, simxGetInMessageInfo could also be of interest.

About additional texture formats... this is not really a priority, but if there are easy and quick options, we might do it.

Cheers
