Our team did the math with alittle help from our mentors but according to our math with a machine 85% efficeint (Geared down by a multistage transmission and 2:1 sprocket ) it would take a round about .0284 horsepower to lift a 150 lb machine 12" in 12 secs with one motor. Our mth might be wrong so dont quote us lol. the question is your bot going to be balanced enough to hold another and is the other robot's weight going to be balanced? If your cant get the solutions for these you risk the chance of tipping urself and damaging your bot and other robots as well. Just my 2 cents of info to keep in mind.
