I am planning to develop an exercise machine for muscle recovery, the idea of the project is to mimic the sensation of fishing so that the exercise has more excitement in an indoor environment.
The idea is that the patient turns a crank and that at a certain moment he/she makes force (variable) so that it costs more to turn the crank. The prototype will have a rod shape to give more sensation.
We had thought of using a motor that makes counter/braking force (protecting it properly with a diode and maybe using a current limiter to be able to control the torque and not to have too much current).
The operation of such a project is as follows, the user would start turning the crank without any effort after a period of time should increase the resistance to rotation. It is also possible that the user would stop turning and continue for a short time afterwards, it would not be constant.
Should the motor be used as a brake all the time? (It is intended to provide a sensation of fishing so there should be a feeling that something is trying to turn the crank shaft in the opposite direction).
Will it be possible to control the braking torque and do I need to add amplifiers so that there is more resistance to the rotation?
Thank you very much
