Re: B0 resolver could not be launched.

Hello,

can you tell me what platform you are running CoppeliaSim on, and what version of CoppeliaSim?

Can you manually launch the B0 resolver? b0_resolver executable in the CoppeliaSim folder.

Cheers

Re: Problem on using URDF

Hello, the error means that the joint does not have any name, in the URDF file. This does not always mean that the file is faulty. But what a simulator expects from a file and what is actually in the file can greatly vary. Does the import operation produce anything? Or what is the problem, next to t...

Re: controlling motor from python

When you say: "...when the motor reach a certain distance the tick next the joint in coppelaism disappears..." makes me think that the joints are not dynamically enabled anymore, after a certain time (i.e. they are not handled by the physics engine anymore). One of the reason could be that it is too...

Re: How can I call via MATLAB the function sysCall_threadmain?

You have several ways to execute some code in CoppeliaSim. The code can be executed in non-threaded mode, or in threaded mode . But if an action is triggered from an external application you can do something like (e.g. in a non-threaded script): function sysCall_init() .... end function sysCall_actu...

Re: Redundant Manipulator Collision Avoidance?

We have prepared a very simple example scene available here: run the simulation and try to move the blue cylinder close to the kinematic chain.

We might add an improved version of this scene to the default demo scenes. Make sure you run with CoppeliaSim V4.2.0 or above.

Cheers

Re: Joint configuration using remote API

Hello Jan, you have several ways how you can do this. First I'd use a customization script that handle that task. You mention a text file that contains configuration data. So the customization script could read the configuration file in its initialization phase ( sysCall_init ), or better, in the sy...

Re: How can I call via MATLAB the function sysCall_threadmain?

Hello, how are you trying to call a script function? You cannot call system callback functions like sysCall_threadMain and similar. You'll have to create a new script function that you then call from your external application via simxCallScriptFunction . Maybe something like: function myThread() whi...

Re: Move Gripper to its own coordinate system

Hello, you can find the documentation that relates to your CoppeliaSim version in your installation folder, in the helpFiles folder. And yes, we have added a new, better path functionality, that is much more scalable and flexible. And we highly recommend you to look at it. CoppeliaSim V4.2.0 has bee...

Re: controlling motor from python

Hello, could it be that the motors are limited in range? If you do the same in a self-contained scene, i.e. without the python client, does it work correctly? Also, you should use the simx_opmode_oneshot operation mode, when simply sending out a function/data, without expecting something is return. ...

Re: Which sensor should i use to get similar behaviour as an LDR

You cannot directly measure the light intensity by looking at a light: the light will not be shown, only its effect on surfaces is seen (illumination of the surface). So instead of having a vision sensor look towards the light source, have it look towards the illuminated surface (e.g. the solar pane...
