I am completely new to arduino projects and motors and I am trying to find the right motor to connect to my arduino UNO to lift a weight of 20kg. After some online research, I understand that most probably i ll have to get a stepper motor and power it from a battery (not from the arduino). However, how much torque should i approximately look for and what other specifications should i look into?
Description of the project:
I want to lift the bottom of a tank without using a rope. I want to pull it from the sides, maybe with a geared system. If the load is too much, I could use two motors to split it.
Hope my description makes sense! Thanks in advance for the information!
