2007 Robot (Mr. Fritz)
Robot Overview
The 2007 robot, Mr. Fritz, consisted of a tall tower that folded into its starting configuration, with a claw mounted to a carriage riding up and down the tower.
Build Season
Strategy
Little, if any, strategic analysis was done before building this game. It was decided that we needed to be able to score on all three levels on the rack, and that lifting other robots for the endgame was beyond our reach.
Prototyping and Design Process
Little to no documentation exists about the prototyping process of the robot or mechanisms.
Fabrication Process
No CNC work was done on Mr. Fritz. All machining was done with hand tools and manual machines. Materials used were 80/20 extrusion, the AndyMark KOP Chassis, and billet aluminum.
Mechanism Details
Chassis and Drivetrain
Fritz used the kit of parts chassis from AndyMark, driven by two CIM motors driven through BaneBots P80 planetary gearboxes and #35 chain to four Andymark 6" wheels, located at the front of the robot. The rear of the robot had two passive casters.
Tower
The tower of the robot was roughly 10' tall made of weight-saved 80/20 aluminum extrusion. Along the side of the tower was a rack gear for the carriage to ride up and down on. To fit in the height constraint, the tower started the match folded, and the carriage pushed the tower up. A gas shock assisted the tower and a latch held it in place.
Carriage
The carriage was also made of 80/20 extrusion and rode on three linear bearings. It was driven by an AndyMark 9015 motor pushing a pinion along the tower's rack.
Claw
The claw had a chassis made of 80/20 extrusion with jaws made of aluminum wrapped in grip tape. The claw was actuated with a lead screw driven by an AndyMark 9015 motor.
