2012 Challenge: Rebound Rumble
REBOUND RUMBLE is played between two Alliances of three teams each. Each Alliance competes by trying to score as many of the basketballs in the hoops as possible during the two-minute and fifteen-second match. Balls scored in higher hoops score Alliances more points. Alliances are awarded bonus points if they are balanced on bridges at the end of the match. In matches where opponent Alliances work together to balance on the white bridge, all participating teams earn additional valuable seeding points (usfirst.org).
2012 Robot: TALON 5.0
TALON 5.0 is the epitome of design by experience; in a unique scoring method, TALON 5.0 opts to quickly and accurately dump balls into the hoops rather than shoot from afar.
The drive train and frame are optimized for the competition, with a U cut out of the middle and a set of four offset wheels, 5.0 is built to traverse the bump and climb the ramp with ease. The frame is a product of fine tuning from several years past and bears a striking resemblance to the "cheesed" frames of the past.
With a lift mechanism perfected last year, 5.0 articulates upwards to drop the three balls it can store in its hopper. A conveyor belt system within a tower at the front of the robot feed balls upwards, and a ball magnet efficiently grabs balls from the ground.
Electrically, the robot contains more technology than ever before. New to 2012 is a drawer glide system to allow for quick and efficient removal of the electrical board. The electrical system is powered by a more compact four slot Compact-RIO from National Instruments and a CAN system is utilized to send and receive data to and from the motor controllers. Additionally, TALON 5.0 boasts more sensors than ever before; amongst the many are a sensor for tallying the balls in the robot at a given time. When the limit of three balls has been reached, the ball magnet automatically is set to deflect balls. Camera tracking and ultrasonic sensors help guide the robot during the autonomous period and during scoring. An accelerometer aids in the balancing of the robot.
Pneumatically, TALON 5.0 employs two separate pistons to actuate a ramp lowering mechanism and the "gate" to drop the balls into the hoop.
