Im trying to build a weird idea for academic purpose. Trying to control a real car using joystick. So for the steering purpose and accelerator pedal, without modifying any internal mechanics, what Im trying to do is to attach a custom device to accelerator pedal and steering column so that it will physically pushes the accelerator using that motorized attachment.
So here are my concerns. With my very little knowledge in motor and these mechanical areas, Im really got confused which is the best motor which serves the purpose. Servo or Stepper. I dont know about these Nema rating as well. So with some theories does Nema 17 does serve the purpose?
Also for both steering and accelerator we should have to hold the positions in some state for some time. So as on considering all these factors Im requesting a good suggestion
