Re: Stable baselines in child script

Hello,

I didn't understand what the exact problem was, when you say that it doesn't seem to work, nor does it give any output... does that mean the CoppeliaSim hangs? Or that the script stops running eventually? Until what point is the script executed?

Cheers

Re: Torque control of joints using Remote Api Python

The model you shared is relatively stable here... with MuJoCo it is even very stable. Please share the equivalent scene file, since there are settings that are not stored in the model and that influence its behaviour.

Re: some bugs about making Spherical joint

Hello, in your MuJoCo model, not all joints are controlled in positions. Additionally, make sure to set all joint's dynamic engine property armature to 20: this is the secret sauce most of the time. When working with Bullet or ODE, you indeed should make sure that masses and inertia are not too diff...

Re: portable export of a compound shape

Hello,

if you select the compound shape, then navigate to [Menu bar > File > Export > Selection (shapes)...] then you can export it as *.dae format (i.e. collada).

Re: 3D printer nozzle simulation

You might also want to look at OC-Trees... those won't display spheres though, but would be ideal for additive manufact.

Re: Adding graph in in a scene

Hello,

actually you are not supposed to add code the the customization script of the graph. Adding graph data points, etc. should be done from within another script, e.g. where the data originates from.

Re: Simulation freezes in Stepping Mode

Hello, it is very difficult to find out what exactly is going on. Normally one should not start CoppeliaSim via a Python script, since this could confuse Qt which requires CoppeliaSim to be started in the main thread. There is however the Python application client in V4.6, that allows to start and r...

Re: Prismatic joint with velocity 0 doesn't hold position.

Hello, this is mostly a normal behaviour: a velocity controller is not a position controller. The controller will try to hold as well as possible the desired velocity, but won't correct for any positional slips obviously. Make sure that your Max. force is large (relative to the exerted forces), as t...
