Re: How to put the motion data and implement dynamically
If you know the whole joint trajectory in advance you can pre-compute perfect velocity acceleration etc. The problem of estimating velocity is so only if you want to do it in realtime (i.e. without knowing future values) then you can only estimate left derivative which is always "late" wit...

Re: ROS 2 plugin is not loading on start up
That's normal.
Plugins are not loaded on startup anymore (probably since V4.5.1). Instead, are loaded on demand, by

Re: The data in the graph will be lost.
Probably you need to set a larger buffer size in the graph dialog.

Re: IK failed: {'notwithintolerance'}
When driving the tip towards the target which initially is not close you'd get a "not within tolerance error".
You can pass
You can pass
allowError=true
in that first stage to allow IK to continue handle it anyways, until it goes within tolerance, then you won't need allowError

Re: Entity exists, but checkCollision is returning entity does not exist error
You can check collision only between shapes or collection of shapes, not with drawing objects.

Re: Why the Revolute joint break when the acceleration happens to the child object of the joint?
Precisely because joints are modeled as ideal kinematic constraints, they do not allow any motion except those granted by the joint degree of freedom. For a revolute joint, that is rotation about the axis, no other motion should happen between the two bodies. Only in an "ideal" world. In ...

Re: vision sensor error
So, does print not work at all? Try in a simple script, e.g.: function sysCall_init() print('Hello') end if it works, then you have some other kind of issue in your code. But you posted incomplete code which is not possible to debug for us. Btw, in your code, if numBlobs is 0 , that print (depthV) l...

Re: vision sensor error
the code gives error saying 'attempt to perform arithmetics on a nil value' which traces back to depth=nearClip+(farClip-nearClip)*depthV[1] (traceback of the error to this function) it means one of those values (either nearClip , farClip or depthV[1] ) is nil. Also, I'm unable to see the output in...
