This looks like a good idea now. I would recommend that you build at least a two particle system and model it fully and even simulate it to see if...
For example you can start with this: https://pydy.readthedocs.io/en/latest/examples/mass-spring-damper.html and make the damping force friction instead of just viscous damping.

I looks like you have a very high value for the viscous effect. Maybe reduce that so that the decay rates are similar for all effects, then you can better...
> I numerically simulated the actuator for positive velocity in [coulomb_positive.ipynb.zip](https://github.com/user-attachments/files/16331062/coulomb_positive.ipynb.zip). The results are as follows: Can you just paste the code here in a comment so we can run...
You need to use the actuators as intended so that you can see if they work correctly. Your code above still manually extracts the forces, which is not the intended...
Good. In the blue line, I thought it should linearly decay with mu_k set to a value. Isn't' that the kinetic friction coefficient?
I just tried this program which individually tries each constant: ```python import sympy as sm import numpy as np import matplotlib.pyplot as plt from sympy.physics.mechanics import (dynamicsymbols, ReferenceFrame, Point, LinearPathway,...
Seems if `v_s=0.0` there is a divide by zero.
I modified the script a bit and found that I have to give a negative mu_k for it to run. This: ```python import sympy as sm import numpy as np...
