2012 Robot: El Toro XV

10 4" wheel drive with a 3/8th inch center offset using 4 CIM motors and all traction wheels
Rotating wedge manipulator for lowering the bridge
Single ball conveyor and a roller pickup, attached to a two wheel, adjustable speed shooter for scoring against the fender
IR Sensors located on conveyor for ball detection
Can score two balls in autonomous, at all three heights, and balance on the bridge
Slanted chassis on both sides to go over the bump quickly

The Game: Rebound Rumble

6 Wheel drive with an 1/8th inch offset using 4 CIM motors and center traction wheels for quick turning
Grabber with 4 treaded wheels and v-belts to quickly grab and manuver all three shapes of tubes
Single-staged telescoping arm with 200 degree pivot to pick up from both sides
Line Sensors for autonomous placing and both anolog and digital encoders to control the arm
IR sensors on grabber for pool tube dedection
Spring loaded slides for quick horizontal minibot deployment
Minibot with 4 wheels and magnets climbs the pole in under 3 seconds

4 wheel drivetrain using 4 CIM motors and 2 high traction wheels in front for auto-alignment over bump and pivoting around ball
Fuzzy roller for ball control and auto-center for kicker
Spring-tensioned, pneumatically actuated kicker
Target tracking with camera
Roll cage for passive self righting

6x4 wheel drivetrain using 2 CIM motors and 2 wheels in the front for weight distribustion
2 Conveyor styles, fuzzy PVC wide belt or 1/2" wide v-belts
Pneumatically actuated "wall" behind the conveyor to allow pickup of balls without shooting them out, can hold 8-9 balls
cRio with gyro to detect angle and auto-correct

4 wheel drivetrain running 4 CIM motors offers speed and maneuverability while racing around the track.
3 stage elevator allows for knocking off the ball from the overpass during hybrid and raises to 8'6" in order to hurdle the trackball.
Pneumatically actuated grabber always for grabbing the ball from the ground and used for holding the ball around the track. Also used to place the ball on the overpass in the end game.
IR board mounted to be used during the hybrid mode.

Picks up 2 big balls Can also pick up 6 small balls (4 reliably) Can balance 2 goals while holding 2 big balls above them to ensure they don't fall off Can grab or release stretcher or goal Can place a big ball on a goal that is on the ramp Flier for El Toro IV The Game: Diabolical Dynamics Game Information Game Manual

The space between bars of the basket is slightly smaller than the diameter of a ball. To pick up balls the robot either pushes balls against the wall or squishes the ball from above.
Could hang reliably

Drivetrain: The four wheel tank drive configuration of this robot allows for a small turning radius, good maneuver abilities as well as a decent speed
The Basket carries eight or more floppies above the eight foot mark
The Basket Raising Belt linked to the basket, enables the robot to raise the basket above eight feet by extending the two stage arm perpendicular to the ground and pulling the basket up
The Leverage Arm rotates and pushes off the puck to lift the back of the robot which allows the rear wheels to drive the robot backwards on to the puck
The Two Stage Arm designed for multiple uses, is capable of blocking other robot's baskets from raising and assists in picking and raising floppies above the eight foot mark
The Floppy grabbing device is able to pick up and release floppies with the aid of velcro
