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...

Re: ZMQ remote API failing after the same amount of runs of a simulation

Hello,

can you tell me what revision of V4.6 you are running? You should have revision 16, or better 18.
Also, make sure you upgraded the related pip package too.

Re: Torque control of joints using Remote Api Python

Hello, the best would be to use the ZeroMQ remote API , since it is much easier and flexible to use, and the legacy remote APi is deprecated. Also, use the latest CoppeliaSim (currently V4.6). Joints when in force control mode need to be constantly controlled/adjusted, i.e. you need to write you own...

Re: Ros2-CoppeliaSim and some bug.

So you have several problems in that scene: The upper and lower cuboids are colliding and friction between them may influence the motion. Make sure that either they are not colliding, or that the upper cuboid is not respondable (or does not generate a collision response with the lower cuboid) Since ...

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

I'd go with a mass for each of the spheres of 2.5 kg. Use the same mass-less inertia for both. If stability is not good with the used engine, increase their mass and/or inertia somewhat.
