Hello Professor, Thank you so much for your reply.
For the first stage, I am trying to optimize the parameters for control of the robot’s locomotion on complex environments including sand and rocks using CPGs. The end goal is to later use RL to implement adaptive control with changing terrains. For the rock sizes, I was looking to implement three rock sizes ranging between 2cm and 6cm filled in a box on which the robot will operate. I am also trying to implement a flexible limb that will be attached to the motors and deform when in contact with some force or the ground, is it possible to implement this to a specified link? I am working with Python and windows, and would appreciate some help as regards this Best regards, Nnamdi On Thu, Jul 24, 2025 at 2:10 AM Dan Negrut <neg...@wisc.edu> wrote: > If you describe what you need to do with your robot, we might be able to > steer you in the right direction. > How big are the rocks you mentioned? > > What sort of end-goal do you have?
