There were 3 iterations of the 2006 robot.
First Iteration: Silicon Valley Regional
- Shooter - gravity loaded, located on (easily defendable) bottom level of the robot. 2 wheels, each powered by 3.5in CIM.
- Hopper - mesh fabric, very high capacity. Able to have balls thrown in from human player station. A spinning 'agitator' was put in place in the center over the exits to shooter and belt to prevent jamming.
- Intake belts - 1 window motor per belt, brings game pieces into/out of hopper.
- Wedge - 10 degree wedge on the rear side of the robot (under shooter)
Second Iteration: Sacramento/Davis Regional and Championships
The robot was simplified during the Thursday of practice matches and inspections in Davis, removing the ineffective shooter, but allowing it to score much more effectively by using the lower one point goals.
- Shooter - removed.
- Hopper - changed shape to hold less balls, but only one point for the balls to exit.
- Intake belt - changed to single belt, 3.5in CIM power.
- Wedge - 10 degree wedge on the rear side of the robot (under shooter, unchanged from SVR)
- Weights - added to bottom of robot to give it maximum traction for optimal defensive power, as much weight was lost in simplifying the robot.
Third Iteration: CalGames and onwards
- Shooter - Located at the top of the robot out of the reach of much defense, 2 wheels, powered by 2 BaneBots motors with gearboxes. Hood was manually adjustable for angle change.
- Hopper - redesigned, allowed for picking up from ground and reliable shift to shooter. See picture.
- Intake belt - longer than before, leading all the way up to the shooter, powered by same 3.5in CIM.
- Hopper director wheel - in some ways replacing the 'agitator,' a wheel which directed balls from the intake belt into and out of the hopper, powered by 3.5in CIM.
Over the years the BaneBots motors powering the shooter were replaced by 2.5in CIMs and the control system was replaced with a RobotOpen system.
Matches were played by 2 alliances of 3 robots each. The field was largely flat with platforms with ramps leading up to them below vertical circular targets at each end, with goals in each corner. The game pieces were 7 inch foam 'poof' balls. 3 points were awarded for each shot made in the vertical goals, and 1 point for each in the corner goals. Additional points were awarded for being on the correct team platform at the end of the match. Unique to this competition, teams could only score during certain parts of each match. The winning alliance of the 10 second autonomous mode (no human control) would be on defense for the first 40 seconds of the match while the losing alliance would be on offense. After the first 40 seconds, the alliances would switch roles. During the last 40 seconds each alliance could score.
- The 10 degree wedge still claimed a few victims, but fewer than 2005's 30 degree wedge; it however did knock over a robot during autonomous mode.
- At some points, the 'agitator' was connected directly to the power distribution board.
- During a pushing match during a match at Silicon Valley, the battery overheated and released a large cloud of smoke.
- At CalGames during the elimination rounds, all the bearings on the drivetrain gave out at once, due to improperly sized spacers grinding away the sides of the bearings. Team 766 was replaced by fellow Silicon Valley Regional champion Team 581.
