Im trying to figure out the best way to make a Helmet G system for a motion setup that uses ardunio uno's for serial input and then controls the motor torque. It will control a lever for moving the rods in 2 directions so you get a 2 DOF. It basically works as a seat mover.
The software used is mainly Pt Mover. FlyPT Mover
This is what i need:
A motor/controller that will apply increasing torque based on the motion data/serial inputs
You can force it backwards against the torque
When no force is applied it free and your head can go back to its neutral position.
What do you think would be the best way to move forward? What motor drivers and so on would one need for the project?
You need to sense the current and run a PID loop to control the current. Thus any motor controller with
current sense output is a good starting point.
To choose components requires first determining the torques and speeds required so the motor can be sized,
then pick the motor driver (so many people seem to do this the wrong way round!). If you can possibly
avoid gearing to allow easy push-back, but without gearing a big torque requires a large motor, compromise
may be needed.
