Quite a few questions I’d like answered for an at home project:
I would like some advice on motor components and the partnering pieces to run with wheels and an Arduino. My first query is to do with 2 normal or gear motors that would be connected to wheels directly (without axle due to shape of design). The wheels need to move (at most) a walking speed and carry around 5kgs along carpet. I would like a stepper motor that has a torque of 20Nm - to rotate up to a 80 degree angle, could you please guide me on what motors would be preferable?
In order to control these 3 motors I’d like to purchase a motor drive shield but I’m unsure of which one would be appropriate, at any one point it will either be the 2 normal motors running together or the stepper motor running on its own, could you also please advise me on this?
I friend of mine suggested a micro controller however I’m using an Arduino Uno and the motor drive shield - is it necessary?
What sort of power source would be required to run these motors, that wouldn’t require the device to be plugged into a wall?
Thanks for all you contributions
