If the steer and roll torque are used to stabilize to the upright equilibrium you can use full state feedback to drive all states to zero. This is a general...

Create a documentation page(s) that show parameter values and figures for all bicycles and riders

1

The idea would be to display all the parameter output values for bicycle and bicycles+riders and show the standard geometry and eigenvalue plots. This would then be an easy place...

Create SVG images to replace beam ascii art

41

See: https://docs.sympy.org/dev/modules/physics/continuum_mechanics/beam_problems.html It would be nicer if each beam ascii diagram was replaced with a nicer looking SVG diagram. Example diagrams can be found in solid mechanics textbooks.

Consider pyvista for visualization

2

This could possibly replace pythreejs. Pyvista is very active and maintained. Only issue is that is requires installing vtk, but that seems to be easy now both with pip and...

Not so clear what configuration we are solving for in the four bar linkage nsolve example

2

There are multiple solutions and I don't really specify why I chose -75 deg and 100 deg as the guesses.

Implement stability constraints

13

It is common in parameter identification problem (or even dual parameter id + trajectories) to find solutions that give unstable systems, even when the measurement data comes from a stable...

Add Gaussian noise to the dynamics for improved parameter identification

Huawei Wang has this paper: "Identification of the human postural control system through stochastic trajectory optimization" https://doi.org/10.1016/j.jneumeth.2020.108580 It seems that the technique is very similar to our noncontiguous example but...
