Figure out how fast you want to lift your robot (how many seconds to lift)

Figure out how high you want to lift your robot (the change in height of the center of mass, in meters)

Figure out how heavy your robot is (in Newtons).

Then you can calculate the power (in watts) required to lift your robot the desired height in the desired time:

watts = Newtons*meters/seconds

Once you know the required watts, you know you'll need a motor with at least that much power. To be sure, multiply by a safety factor.

Then, gear that motor so that when it is spinning at half free speed (max power), it will lift the motor the desired distance.
