inverse dynamic

I want to control the robotic arm to move according to a specified trajectory through torque control. How can I use inverse dynamics (inputs are joint position, joint velocity, joint acceleration and external force) to obtain the torque value of each joint?

Re: show object's trajectory

Hello, a simple way to display a trace of the object, is to add a child script to the object with following content: function sysCall_init() h=sim.getObject('.') dr=sim.addDrawingObject(sim.drawing_lines|sim.drawing_cyclic,2,0,-1,300,{1,0,1}) pt=sim.getObjectPosition(h,sim.handle_world) end functio...

show object's trajectory

There is a force sensor at the end of my robotic arm. With the movement of the robotic arm, the force sensor also moves. I want to display the movement trajectory of the force sensor in the scene. I read many tutorials and said that Graph can be set, but I found that That method should only be used ...

looking at the other post you made, you already know you should use simIK.findConfig.

Have a look at the example scene scenes/kinematics/computingJointAnglesForRandomPoses.ttt

Cheers
I truly appreciate your timely help!

model position adjustment problem

I want to place a small ball on a table, how can I adjust the position of the ball in the world coordinate system so that the ball is exactly on the table, and its spherical surface is tangent to the table?

simIK.findConfig problem

When I use simIK.findConfig to solve a 7 joints arm's end_effector pose to joints configuration, I keep getting the wrong value(different from the current joints' configuration), what should I do?
