T-RO Representation-Free Model Predictive Control (RF-MPC) on Quadruped Panther

[@xianshengyang9191]

could you please open a course to introduce your papaer about rf-mpc ,thanks a lot ,too many formulas in the paper about linearlization about eular equation

[@MechDickel]

Wow, nice quad!

[@YanranDing]

Thanks!

[@idkEngineering]

Why didn't you track orientation with quaternions to fix the backflip (45 deg) gimbal lock issue?

[@YanranDing]

We made the decision to use the rotation matrix instead of quaternion because (a) quaternion has the unwinding issue (b) the difficulty appears to be similar either way

What brushless motor you use?
