Re: Simulation freezes in Stepping Mode

Hello,

make sure to use the latest CoppeliaSim, since CoppeliaSim V4.6 features a much improved Python support.

Re: Why the Revolute joint break when the acceleration happens to the child object of the joint?

Yes, that is correct, only MuJoCo and the newer Bullet engines have ideal joints (but not the Bullet engines in CoppeliaSim as for now)

Re: Designing an Omnidirectional Mobile Robot: Confusion Arising from KUKA Omnirob Model

The reason is following: A real-world mobile robot (or a real-world chassis, beam, etc.) always has some compliance. Additionally, a real-world vehicle often has some suspension or tires. With a physics engine, the compliance does not exist, or is very very small and due to numerical imprecisions, e...

Re: finding center of mass and parameter's assigning

You can find all physics engine related properties for shapes when you click engine properties in this dialog.

Re: simulation of a generic lidar sensor

The velodyne model basically operates in a very similar manner as a simpler laser range finder: the range finder uses a vision sensor instead of a proximity sensor to do distance detections, mainly because of speed concerns. With a vision sensor you can acquire a depth map at once. Using the depth m...

Re: sim.saveImage causes the script to freeze/crash

I tried on Windows here too, using CoppeliaSim V4.6 rev. 18.
Is the error message still the same? Can you make sure that the patched sim.saveImage is actually ran, e.g. by adding a print in there?

Re: How to add Object Detection

Hello,

have a look at the demo scene scenes/vision/objectTracking.ttt, it should illustrate everything you want to do.

Re: sim.saveImage causes the script to freeze/crash

Hello Fabio, indeed, this is a bug! Do following for a workaround: edit file <installFolder>/addOns/ZMQ remote API server.lua by appending following: sim.saveImage = wrap(sim.saveImage, function(origFunc) return function(img, res, opt, nm, q) local ret = origFunc(img, res, opt, nm, q) if type(ret) ~...
