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...

That's normal.
Plugins are not loaded on startup anymore (probably since V4.5.1). Instead, are loaded on demand, by loadPlugin() or by lua modules (e.g. typically, simFoo.lua will loadPlugin('simFoo') if "Foo" is a plugin).

Code: Select all

--lua
    sim.setObjectPose(simTarget, {-k * centerX, k * centerY, 0, 0, 0, 0, 1}, simTip)

you are setting position of simTarget relative to simTip's reference frame.

Probably you need to set a larger buffer size in the graph dialog.

When driving the tip towards the target which initially is not close you'd get a "not within tolerance error".
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 anymore.

You can check collision only between shapes or collection of shapes, not with drawing objects.

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 ...

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...

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...
