Simulation stops when getting data from a 3D Laser scanner

I am using V-rep with Python Remote API. The 3D Laser scanner (provided in Model browser) is based on a vision sensor. I can get the measuredData which contains all the points that are closer than the sensor range. I used the function sim.setStringSignal("measuredData",data) to send the data, and I ...

simulation slows down with multiple robots

Hi,

I'm experiencing significant slowdown with multiple robots (4 baxters in my case), is this normal? Is there any way to prevent this?

Thanks

Attach frame to model

Hi, I was wondering if it's possible to attach a frame to a predefined position/orientation on a robot's gripper and have the frame always follow the motion of the gripper (static relative to the gripper's center frame). Thank you.

Re: Path planning using remote API and synchronous mode

Thanks for your reply. What you suggested works well in pure simulation, but I want to construct the code so that transferring to actual hardware will be trivial. Therefore I guess I should write as little lua code as possible. Is it possible to write the planning part in C++ or python (a plugin may...

Path planning using remote API and synchronous mode

Hi, I saw this statement in one of the earlier posts "What takes long, is not the collision checking in itself, it is the way you use the remote API. Also, doing path planning via the remote API is probably not a good idea, since you don't have fast synchronization, and always suffer from the lag of...

Contrain motion to certain DOF

Hi, as per the title, I was wondering if there's a quick way to constrain the motion of my robot to say only move in the z direction and fix the other 2 translational and 3 rotational DOFs.

Thank you

Re: Python remote API in synchronous mode

One more question that came up is that if I'm using simxSynchronousTrigger and in the simulator dt=50ms which is the default, does that mean my simulation no longer updates every 50ms but updates according to the frequency simxSynchronousTrigger is called? If so is there a convenient way to measure ...

Python remote API in synchronous mode

Hi, As per the title, I'm trying to send my control commands using simxSynchronousTrigger in synchronous mode, the simulation updates at the default rate of every 50ms. However the rate at which I'm sending the commands at the remote side is most likely not every 50ms, so I was wondering how Vrep de...
