TRANSCRIPT
Basics, RoboCrossGoal, 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 yearMotion 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, RoboCrossMust fit in an imaginary 28 cm by 28 cm by
28cm cube. Remote control, wire or radio allowedKits must have SOME functional modification
Playing Field, Robo-cross
Competition, Robo-Cross No Setup time or practice time mentioned, 3
minutes to complete taskTime starts on go of supervisor “3, 2, 1 Go”Time stops on
Three minutesStudents say “SCIENCE”Students touch robotTeam steps into playing field after being
warned onceRobot moved by control wiresAny part of robot or jug leaves Playing Field
Scoring, Robo-CrossScore based on where objects placed, harder
places earn higher scores, to a point.Objects get higher scores if put jugEven higher score if you get same object in
BOTH jugsObjects leaving the Playing Field AND touching
down at any time are NOT scored5% penalty for partial documentation, 20%
penalty for NO documentationTime explicitly part of score, drives strategic
thinking, is that last penny worth chasing!Ties broken, then lowest mass
Some thoughts on designThe 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
