Game: RoboZone Judging

Robofest 2009 Game Summary UP (Unknown Problem) Challenge – drawing unknown shape Top rank UP teams will select the rest of group members by raffle UP results will be the tie breaker to select the best team for each group RoboZone Group tournaments in parallel Semi-Finals / Final

A sample UP drawing (1) 300mm (2) 150mm 90 o

One practice paper will be given. The robot must not be touched by players during the work. Once touched, the drawing cannot be continued. If the pen of the robot goes out of the paper, the robot must be stopped immediately. Record and play function (NXTG) cannot be used. Before the given drawing time is expired, turn in your robot to the judging table. If not, no game! Tape/mark your team ID on the robot Judge will call a team member to test the drawing UP drawing Rules

How would you rank them? (1) 300mm (2) 150mm 90 o 35.2 cm 16.4 cm 89 o 39.4 cm 22 cm 119 o 40cm 21cm 95 o Robot went outside the paper 50cm 119 o 25cm 21cm 8cm

Drawing Judging Need two or three judges dedicated to this judging to maintain consistency First select best n teams, where n is the number of groups for each age division Let the best n teams select group members by raffle During the RoboZone game, the judging needs to be completed

How precise the line lengths are. The deduction can be quantified by difference. How precise the angle is. Deduction can be quantified by difference. How clear/solid the lines are. Deduction can be quantified by the size of the largest gap. How straight the lines are. (See next slide) How sharp the angle is. (See next slide) How to score drawings

Draw a rectangle that contains the entire line drawn by the robot. The width of the rectangle is the deduction. How to quantify line straightness 14 mm

Draw a box around the angle blip. The deduction is the diagonal distance of the rectangle How to quantify an angle quality d = 21mm d = 42mm

If the pen of the robot goes out of the paper or is stopped by human, 50% of the sum of the target lines will be deducted Any line drawn outside paper will be ignored If a line is not drawn at all, then the penalty point is double of the line length in mm If extra line is drawn, the it is regarded as an extension of the previous line Additional Penalties

RoboZone Game Rules A match consists of up to three games. The first robot to win two games wins the match Maximum time for each game is 2 minutes Only one team member is allowed to enter the competition area to start the robot. A judge will weigh and measure the robots before the match Jr. DivisionSr. Division Max. length and width25 cm Weight of the robot1kg (2.2 lbs)1.3kg (2.9 lbs)

How to start a RoboZone Game For each game, the judge will designate the starting location and orientation for each robot

After a Game is Started Each robot must wait for 5 seconds. If a robot moves, during this wait-time, the robot loses the game automatically. During the 5 second wait time, a judge will place the Zone and bottle at an unknown middle location between the two robots considering the size (width and length) of the two robots. The Zone must be taped down on the table Both players and judges MUST move back out of the way at least 10 feet

No human touch is allowed. Reset of the playing field is not allowed. Judges will have discretion in making decisions during the game and the judges decision is final. The max break time between games is 2 min. teams should shake hands after the match Once the game is started/ended

Occupy the Zone or push the opponent off the ring! If both robots survive for 2 minutes without occupying the zone successfully, the game is tie. If the match results in a tie (for example: one win, one lose, and one tie) Scorekeeper records tie. The drawing rank will be used to determine a winner, if needed How to win a game/match

Target center point must be completely covered with any part for 3 continuous seconds. The robot may move. A detached part from a robot covering the target center point does not count. The counting will continue, even if two minute game time is elapsed. Definition of the Zone occupation Target center point of the Zone

Site Hosts needs to prepare a national flag!
