Connect 2 cuboids to one Shape

[Sena]

Sorry for my bad explanation

Here is the image : https://ibb.co/4syxx8M
(red : cuboid / blue : cylinder)

So i'm controlling the position of L_Elbow & L_Shoulder via Python.
And i want the cylinder to follow those cuboids as you can see in my drawing .
Is it possible ?

Finally!

Ok, you have severasl ways. Normally, you would use inverse kinematics to do that. e.g.:

Code: Select all

shoulder --> sphericalJoint --> arm --> dummyTip
elbow --> dummyTarget

maybe even something like:

Code: Select all

shoulder --> sphericalJoint --> arm --> sphericalJoint --> dummyTip
elbow --> dummyTarget

Just make sure your shapes are not dynamic. And have a look at the simple IK example in scenes/singleIkGroupWithSingleIkElement-undamped.ttt

Another possibility of course would be to compute the position and orientation of the arm, and update it via sim.setObjectPosition, sim.setObjectOrientation and/or sim.setObjectMatrix. Here too, make sure that your shapes are static.
