We are gearing up for competition this weekend at Howell and snapped a couple shots of our 2013 robot, “Rohrbot” – named for a former mentor who was instrumental in building our program.
Overall, the robot is fairly simple. It is designed to pick up the exercise balls from the floor using the gathering arm in front, and has a winch powered catapult that is designed for close range launches.
Good luck to all the teams! We look forward to sharing the fun with you.
