Hi there,
I'm building my own robot arm based on wiper motors because I already have them, and because I know they are strong. However, when doing the math on the torque needed to lift the robot, it seems like the motors one will have to use must be extremely light and powerful. If using one wiper motor with 10 Nm torque, it is only capable of holding a mass of 1 kg in 0.5 m (length of the robot arm + assumed of no mass).
If the robot should at least have one more arm, it must be very light, and the robot will not be able to lift anything bu the robot arms. Is this really the case? I would prefer not to use additional gearing due to the pricing and weight of gears along with the already slow velocity of the wiper motor.
