Anybody interested in taking part in techfest 2005? http://www.techfest.org Im making a robot for this techfest. One of my main objectives is to have a transmission system on the robot, because the robot has to climp steep inclines. I have designed a 2 speed automatic tranny, and I hope it works. Power to weight ratio and low-end torque are the key ingredients here. I didnt want to increase the power to weight ratio by cutting down on structural components....the robot has to have structural rigidity when it jumps down that incline. Tranny should solve the problem.
