Features

Drivetrain:

• 4 small CIM motors
• 2 AndyMark, Inc., pneumatic shifting gearboxes
• High Gear Speed: 12 ft/s
• Low Gear Speed: 6 ft/s
• 4 AndyMark OmniWheels, two placed side-by-side on each side in front to reduce "jitter" that occurs when using only one OmniWheel per side
• 4 AndyMark six inch wheels, two per side, one in front of the other in the back of the robot--these came in the kit
• Powerful, simple, robust, and easy to maneuver
• Wheels supported by slotted C-channel, eliminating need for pillow blocks and slots in the frame

Robot Frame:

• 1/16" X 1" X 1" aluminum box
• Total dimensions: 37.5" X 27.5" X 60" (with ~1" ground clearance)
• Welded for maximum weight and strength
• Approximately 110 lbs total weight
• 5' height category

Arm:

• Design based in part on Rowdy 6.0 arm
• Single-joint design simplifies mechanisms
• PVC cellular core schedule 40 used because of its weight advantage
• Joint driven by Window Motor
• Pneumatic extension: 1.5" bore and 8" projection
• Gripper actuated by 3/4" bore and 6" pneumatic cylinder
• Capable of reaching all three scoring heights and picking up from ground quickly

Ramps:

• Elevate robots to 14" above ground
• Once released, entirely mechanically actuated
• Robots drive directly from field onto ramps
• Approximately 23 degree incline
• Lightweight, but strong and durable
• 0.060" polycarbonate platform and ramp on 3/4" X 3/4" X 1/16" aluminum box frame

Electronics:

• 5 Victor 884's (4 in drivetrain, 1 in window motor in arm joint)
• Removable electronics box with main plugs for most connections

Pneumatics:

• 2 SMC solenoids to actuate the arm
• 32 feet of Frelin-Wade tubing
• Festo to shift the Andy Mark gearboxes
• Pneumatic extension: 1.5" bore and 8" projection
• Gripper actuated by 3/4" bore and 6" pneumatic cylinder
