Robo-Cross Div B Jeff Anderson or

Basics, RoboCross Goal, move a variety of objects quickly to from starting point to a target location and place them in a jug. All within a 4 by 4 ft sq area. Mobile Robot base, attachments to pick up and move objects Objects include Ping-Pong balls, pennies, tennis ball, and Lego bricks Scored by difficulty of task, with penalty for incomplete documentation Three minute limit to accomplish task

Power, RoboCross 14.4 volt maximum in any given circuit, ES has to be able to check batteries No stored pressure device this year Motion may be generated only by electrical, elastic, or gravitational energy. These forms of energy must not be converted to other forms such as hydraulics or pneumatics to power the Robot. NO operator powered motion.

Building Specifications, RoboCross Must fit in an imaginary 28 cm by 28 cm by 28cm cube. Remote control, wire or radio allowed Kits must have SOME functional modification

Playing Field, Robo-cross

Competition, Robo-Cross No Setup time or practice time mentioned, 3 minutes to complete task Time starts on go of supervisor “3, 2, 1 Go” Time stops on Three minutes Students say “SCIENCE” Students touch robot Team steps into playing field after being warned once Robot moved by control wires Any part of robot or jug leaves Playing Field

Scoring, Robo-Cross Score based on where objects placed, harder places earn higher scores, to a point. Objects get higher scores if put jug Even higher score if you get same object in BOTH jugs Objects leaving the Playing Field AND touching down at any time are NOT scored 5% penalty for partial documentation, 20% penalty for NO documentation Time explicitly part of score, drives strategic thinking, is that last penny worth chasing! Ties broken, then lowest mass

Some thoughts on design The field is allowed to be broken down for transportation, barriers are allowed a range of sizes. Don’t prepare for best case, prepare for worst/all cases. Both design AND practice are important. Tethers don’t have interference with other devices, BUT may cause problems if they drag on playfield Use modern RC control to avoid possibility of interference, ES will not protect you
