Contact Forces/Torques for Robotics Applications
7 views (last 30 days)
I am using Robotics Systems Toolbox in Simulink and performing dynamical simulation. The simulation consists of a free movement and then a contact arised from a peg-in-hole task.
Because of the contact, I need to pass the reaction forces and moments back to the robot (by multiplying with the transpose of the jacobian of the end-effector of the robot in order to convert them to joint torques) to include contact effects on the robot.
As fas as I see, either Simulink Multibody Contact Forces Libary or Spatial Contact Force Block only gives normal forces in scalar, not vectoral.
Is there a way to get forces and torques in vector format to feed robot for contact dynamics effects?
Thanks in advance.

The Spatial Contact Force Block will automatically apply the forces to the elements connected to its two ports. You don't need to feed the forces yourself. The magnitude of the forces can be outputed by checking the Sensing option of the block.
