Team 4004, the M.A.R.S. Rovers, achieved consistent tower scales last weekend at West Michigan. Our robot's 'Intellihook' activated the winch automatically as soon as the hook made contact with the bar. It took the guesswork out of our drivers who couldn't always tell if we were hooked properly or not.
