  1. Sumo Introduction Fall 2011

  2. theCOMPETITION Crash course in robotics for the inexperienced/curious.

  3. theTOOLS • We’ve designed a custom PCB specifically for the competition. You solder it together. • We give you sheet metal. You design and build a chassis. • We give you a firmware API. You design and implement a software strategy.

  4. designHINTS • Most effective designs usually incorporate some sort wedge • Simple designs are more effective • Keep in mind how the chassis is going to be manufactured to ensure ease of construction

  5. minisumoBOARD • Robots are controlled by a microcontroller • MiniSumorobots use Atmel ATMega168 16 KBProgram ROM 1 KBRAM 16 MHzClock Speed • Teams will develop software that runs on the microcontroller

  6. developmentTOOLS • Cprogramming language • Arduino IDE • Serial Port

  7. arduinoIDE Write code Compile Upload Debug

  8. serialPORT • Remember these? • Very common in the • embedded world • You will use it for • Uploading software to the board • Debugging

  9. exampleSOFTWARE • Example software is available on the Robotics Team website. • Fully functional • Interfaces with motors and sensors • Basic control logic • Excellent base for custom code

  11. sumoRULES The following slides outline the rules of the competition. • There are many rules • Most are based off ridiculous suggestions from the past • The rules are available on our website

  12. sumoRULES • 12 cm x 12 cm is base limit • Robot must weigh less than 500 g • Chassis can be built without the sheet metal provided if desired but may not be kit built • Robot may not fly • The robot must have a name

  13. sumoRULES • Must be completely untethered and autonomous • Must be battery powered • No compressed gas or other dangerous material may be used in competition • No active jamming devices may be used • Magnets may not be used

  14. sumoRULES • Before moving, robot must delay 5 seconds after switch is thrown • No parts may be jettisoned from robot, including smaller robots • Minor loss of parts during competition is acceptable, subject to judge’s discretion

  15. sumoRULES • Pushing is the only acceptable form of offense. • No spinning, sprung or other forms of weaponry are permitted. • The robot must not employ any sort of device or material intended to hold the robot down. • Rubber tires are acceptable, super glued tires are not.

  16. arenaRULES • Arena is a non-reflective black surface surrounded by a white painted ring • 770mm internal diameter • Sample rings will be made available for public testing during the days approaching the competition.

  17. matchRULES • Robots will begin the match • side by side, • facing in opposite directions, • no more than 200 mm away from the edge of the ring, • With the center of the ring between them.

  18. matchRULES • On the judges’ signal, each team will press a start button on their robot. • The robot must delay for at least five seconds before beginning movement.

  19. matchRULES • The match will last for three minutes or until the first robot has exited the ring, whichever occurs first. • A robot that has exited the ring loses the match • “Exiting the ring” means having the entirety of the robot cross the white painted line

  20. matchRULES • If a robot is disabled and hasn’t moved for 15 seconds, it is disqualified. • Rules for ties will be finalized and announced when the competition format is set

  21. judgingRULES • Judges will be determined prior to the event of competition • Robots will be judged on design, creativity, appearance, as well as performance • The robot that wins the tournament does not necessarily win the competition • Tournament format will be announced approaching the day of the event

  22. judgingRULES • The overall winner will receive a cash prize in the range of $300-500. • Smaller prizes may be awarded to 2nd and 3rd place teams subject to availability

  23. thisWEEK • Electronics tutorial starts Wednesday at 6:30pm in E5-2004. • All teams must attend • Kits will be distributed

  24. thisWEEK At ~7:30pm, TWO members from each team will go with us to the Church Lab in E3X to the first soldering tutorial/session. • Lab room cannot fit any more people • Team members are welcome to rotate roles for future sessions • We will gladly teach concepts to team members during any lab session • You will not lose out by not attending the first session

  25. questions? • This presentation is posted on our website • You should check our website often http://robotics.uwaterloo.ca/
