Re: V-REP / ROS applying force

Hello, You can do as follows: Prepare a non-threaded child script. Something like: if (simGetScriptExecutionCount()==0) then simExtROS_enableSubscriber("/rotorXForce",1,simros_strmcmd_set_float_signal,-1,-1,"AnySignalName") forceValue=0 end signalValue=simGetFloatSignal("AnySignalName") if (signalVa...

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: How do I rotate a single object around 1 axis in simulat

Geerten, this is not a programming course, questions and answers should be specific to V-REP (i.e. I pointed you to the right API functions). Regarding Lua programming language or its constructs, please refer to their website and other online documentation. Make sure also you read and search the V-R...

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: Simulation Help

Hello,

It is actually very difficult if you have little programming experience.
I suggest that you try to follow this tutorial as a start, to get an idea.

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: Accelerometer or Gyroscope

Hello Nikolaus,

It appears that the warning message is wrong!
Just ignore it, and we'll try to fix that for next release.

Cheers
