Re: how to send data from matlab to CoppeliaSim

Hello, to send data over to CoppeliaSim, simply call sim.callScriptFunction and make sure you have an appropriate script function in the Lua script to receive and process the data. Also make sure that the script is initialized at the time it is called from MATLAB. By the way, I hope the frequency of...

Re: Using Joint target position with Python Coppelia API binding

Hello, if you want to control a joint or kinematic chain in 3D space instead of joint space, then you should use inverse kinematics (IK) . In your case, if you want a joint to follows a specific 3D point, try with this exercise: Make sure your joint (for now) is in kinematics mode attach it to an ob...

Re: inverse kinematics in v4.6.0

If you want to understand IK, then best would be to read/follow this section , in particular that one . This tutorial about IK is also available. You can also very easily set up IK by doing following: Start with a raw model, e.g. Models/robots/non-mobile/7 DoF manipulator.ttm If it has a script atta...

Re: Can not be remote with MATLAB on Mac

The legacy remote API is deprecated. We highly recommend to switch to the ZeroMQ remote API , which is now de facto the default remote API. With the legacy remote API, there was never simRemoteApi.start(19999) in the main script. But in any case, you can call simRemoteApi.start from wherever you wan...

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

From first tests, it appears that sim.loadScene is the culprit. This bug somehow also happens with sim.loadModel. A first workaround would be to avoid constantly reloading the same scene/model: after a simulation stop, the scene should anyways be mostly restored to its original state (i.e. just befo...

Re: Can not be remote with MATLAB on Mac

Hello, I am not sure I understand your problem... if I understand you correctly, you are trying to use the ZeroMQ remote API via MATLAB, but that doesn't work. What is the problem? Is there any error message? What CoppeliaSim version are you running? What kind of relative code in the main script are...

Re: How to get the angle change of rotating joints during simulation

Hello,

there are several functions related to 3D transformations you could use. But best is probably to use sim.getRotationAxis. Make sure to also read the section on positions, orientations and transformations.

Re: Asti model

Hello,

the Asti robot is inspired by Asimo, the humanoid robot from Honda. Asti does not exist in real.
