Hi, I am building a two wheel robot with a ball caster at the back.
I am using a 50:1 Metal gear motors Qty: 2.Q1.
The weight of my robot is 12oz
Total including everything (motors, battery etc etc). The stall torque of each motor is 15oz. As i am using two motors i think i should be ok. What you guys think? Q2.
Moreover, will i be right if i say i am using two motors so the weight of my robot will be equally distributed on the two motors and the ball caster. As the ball caster is only being dragged. So each motor will see the weight of the robot to be like approx 6oz?
Here are the specs of the motor:
Gear ratio: 50:1
Free-run speed @ 6V: 630 rpm
Free-run current @ 6V: 100 mA
Stall current @ 6V: 1600 mAStall torque @ 6V: 15 oz·in
