Having taken my fair share of physics I do not for the life of me understand how this is possible.
More force should equal greater acceleration, for the same mass. Correct?
They will reach the same speed, but the 4 motor bot will accelerate faster.
So did they reach the end at the same time simply because the 2-motor bot's lightness made up for its lack of power? 
After several transmission/motor swaps in '08 our team pretty much convinced ourselves that 4 motors was ALWAYS the way to go. |
4 motors give out too much torque, which when there is low traction just spins the wheels. If you have ever watched a drag race where a car didn't heat up the tires well, they go, but also just spin the tires down the track. The trick for this year is finding the right amount of torque i think.
