CoppeliaSim forums

Hello,
I am trying to simulate the motion of a sphere on a flat surface under an applied torque T = [Tx, Ty, Tz] expressed in the body coordinate frame, and a viscous damping force F = [Fx, Fy, Fz] expressed in the inertial reference frame.
I created a sphere model in CoppeliaSim 4.9.0 (rev. 6) and ...

Thank you for your response.
I have used the MuJoCo engine for this problem with its default settings. As you mentioned, achieving a perfect dynamic simulation is not possible. However, I would like to model the rolling constraint between the spherical robot and the ground as closely as possible to ...

Hello,

I’ve created a model of a spherical mobile robot rolling on the floor, actuated by two internal rotors. The motion is based on the conservation of angular momentum, and I apply motor torques to simulate the robot’s movement.

However, during faster or more complex motions, the spherical ...

Hello,
I have an object that moves in x-z plane and rotate about its Y axis. I want to obtain its rotation angle around the Y axis. So, I use sim.getObjectOrientation() function and use the second element of its output as the rotation angle of the object. However, this value is between -90 to 90 ...

Hello,

I have modeled a spherical mobile robot in V-REP which composed of a spherical shell and two internal rotors. I have used a primitive sphere as the spherical shell and design the rotors using two primitive cylinders. I have set the sphere to be respondable and dynamic and the rotors and ...

It works properly.
Many thanks Ferri.

Thank you so much for your response. The module I have developed is named Inteligent_Controller, and when I import it in the child script, the error message " No module named 'Inteligent_Controller' " is shown.

Hello,
I have developed a Python library consists of some functions and classes and want to import it in a Python Child Script in V-REP. Could you please help me how can I import it? I have copied the .py associated file in the current directory of my V-REP file, but the module could not be imported ...

Hello,
Thank you for your reply.
I use CoppeliaSim Edu Version 4.5.1 (rev. 4) 64bit on MS Windows 10. I also made the changes you suggested in lua/pythonWrapper.lua, but the problem still remains unsolved.
regards.
