Re: How to Import a URDF file

Yes, the URDF importer is very finicky about the resources' paths, and often those need to be adjusted...

Re: How can I limit the working space of the robot?

There is an option to avoid joint limits in simIK.setGroupFlags: simIK.group_avoidlimits : joint limits are actively avoided A more customizable approach to drive the robot configuration towards "better" poses could be of introducing a secondary task, e.g. to attract the elbow up, without ...

Re: Rotate an object from API

eulerAngles = sim.getObjectOrientation(shapeHandle, sim.handle_world) eulerAngles[3] = eulerAngles[3] + amount sim.setObjectOrientation(shapeHandle, eulerAngles, sim.handle_world) Notes: sim.handle_world is the default, so it is not required to specify it; objects rotate around their origin. Arbitr...

Re: Java ZMQ Remote API

Make sure to use the latest version of CoppeliaSim. You are using an old version. In the latest version of Example.java there are more examples. About your other question: Object[] is an array of Object which is the superclass of all types, indicating a no better specified type. Object[] is used as ...

Re: Java ZMQ Remote API

The point is that sim, simT and the result of RemoteAPIClient.getSim() are all the same thing which you are fetching three times.

just wanted to make sure wether you understand the Java ZMQ remote API client interface...

Re: DH parameters

The concept of robot configuration aims to conveniently represent a robot as a vector of joint positions. If the robot geometry is the same (same DH params, same joints ranges & orientation), the same robot configuration vector will describe the same pose both in CoppeliaSim and in Robotics Tool...

Re: How to input the data of RGB image gotten by Coppeliasim into Matlab

From zmqRemoteApi/clients/matlab/synchronousImageTransmission.m:

Code: Select all

    [img, resX, resY] = sim.getVisionSensorCharImage(visionSensorHandle);
    % display image in MATLAB:
    imshow(flip(permute(reshape(img, 3, resY, resX), [3 2 1]), 1));
