Excite three muscles to minimize the error of the hip flexion, knee angle, and ankle angle coordinates.

Do not spend a lot of time trying to match the IK solution: it is challenging to do by hand and there are OpenSim Tools that do this (which we will explore below). Simply aim to reduce the error relative to the "FWD_locked" simulation (i.e., with no muscle excitations). |
- By exciting a single muscle in early swing, reduce the error of the hip flexion coordinate in the forward simulation.
- By exciting a second muscle along with your previous excitation, reduce the error of the hip flexion and knee angle coordinates.
- By exciting a third muscle, reduce the error of the hip flexion, knee angle, and ankle angle coordinates.
