"noetic" is ROS 1, not ROS 2

The joint position/velocity refers to the instantaneous (current) value.

The target position/velocity it is the target value used by a controller or motion profile (see Joint modes) that will be eventually reached.

Yes, you can use any of these API functions to move/rotate objects: sim.getObjectMatrix sim.setObjectMatrix sim.getObjectPose sim.setObjectPose sim.getObjectPosition sim.setObjectPosition sim.getObjectOrientation sim.setObjectOrientation sim.getObjectQuaternion sim.setObjectQuaternion See also posit...

The Python zmqRemoteApi client uses dynamic dispatching, thus you cannot have information about functions in your IDE.

If you look in the statusbar at the bottom of the screen, you'll notice that you have a script error: [/Pioneer_arm_carrier/UR5@childScript:error] [string "/Pioneer_arm_carrier/UR5@childScript"]:302: attempt to get length of a nil value (local 'c') stack traceback: [string "/Pioneer_a...

There was an error in CoppeliaSim 4.4.0's lua/efficientConveyor_customization-2.lua.
Here you can find the updated file (save it to CoppeliaSimEdu/lua/efficientconveyor_customization-2.lua).

Those issues are an indication of a poorly designed dynamic simulation.
Have a look at the design considerations in Designing dynamic simulations (especially 6, 7 and 8).

The CustomUI's plot widget only supports line plots. A more flexible option would be to use the QML plugin , e.g. you can display a view with a QtQuick Canvas in it, and provide your own drawing implementation, where you would pass the data to draw via an event ( simQML.sendEvent(engine,eventName,ev...

sim.getObject("./joint{0}"); will only work in the (to be released) CoppeliaSim version 4.5.0 or later.

You either use sim.getObject("./joint{0}"); (the same syntax works in Lua) or use the second argument, which is a lua table argument, and like I explained in the other post you would use a json object for that, e.g.: sim.getObject("./joint", json(json_object_arg, {{"index&qu...
