Well, in order to
lift the robot you'll actually have to accelerate its mass, so you'll need more than 150 lbs. of force.
Also keep in mind that you'll need to calculate the output of the reduction at 1/3 the CIM's stall torque for max power. A CIM at stall will not lift your robot
You could add a chain or compound pulley reduction off of your T-Box to get enough force.
We found that a 70:1 reduction with a 2" dia pulley lifted the robot without tripping the breakers.
