  1. 2.007 Strategies Adam Paxson

  2. Strategy 1: Rotating Arm • 2WD robot will drive to one of the ‘2’ or ‘7’ compartments to deposit the balls in the ‘0’ bins • Balls will be picked up and moved by a rotating arm • One motor can be utilized for actuating exponent arrows

  3. Strategy 1: Rotating Arm 5 seconds: move in front of bin

  4. Strategy 1: Rotating Arm 5 seconds: open compartment

  5. Strategy 1: Rotating Arm 30 seconds: move and deposit balls

  6. Strategy 1: Rotating Arm 5 seconds: move exponent arrow

  7. Strategy 1: Rotating Arm • Scoring: • Specific and pre-defined movements • Small allowance for error • Defense: • No dependence on roaming • Not enough time for other robot to block • Offense: • No offensive aspects; inadequate propulsion

  8. Strategy 1: Rotating Arm • Predicted score range: • No balls from the bin, only held balls are deposited, arrow is not moved: • (0balls+0kpucks+1)bottom bin(5balls+0Npucks+1)0 bins20 = 6 • No balls from the bin, only held balls are deposited, arrow is moved: • (0balls+0kpucks+1)bottom bin(5balls+0Npucks+1)0 bins24 = 96 • All the balls from the bin and held balls are deposited, arrow is moved: • (0balls+0kpucks+1)bottom bin(20balls+0Npucks+1)0 bins24 = 336

  9. Strategy 1: Rotating Arm • Risks: • Balls roll too far out of bins, not able to pick up • Opponent prevents arm from rotating • Opponent moves exponent arrow • Countermeasures: • Attach a fence to prevent rolling • Attach a guard to protect rotation • Make arrow mechanism “clamp”

  10. Strategy 2: Puck Lifter • 2WD robot has an arm that lifts and drop pucks • Pucks are put in both scoring areas to take advantage of multiplier • Puck arm can also move the exponent arrows • Robot also scores 5 held balls

  11. Strategy 2: Puck Lifter 5 seconds: collect 3 pucks

  12. Strategy 2: Puck Lifter 5 seconds: deposit pucks and balls

  13. Strategy 2: Puck Lifter 5 seconds: gather remaining pucks

  14. Strategy 2: Puck Lifter 15 seconds: deposit pucks into ‘0’ bin

  15. Strategy 2: Puck Lifter 10 seconds: move exponent arrow

  16. Strategy 2: Puck Lifter • Scoring: • Utilizes bottom bin; reduced risk • Arm could possibly lift balls • Defense: • Scores quickly; little chance of early disruption • Lifting arm can tip aggressors • Offense: • No tactics; inadequate propulsion

  17. Strategy 2: Puck Lifter • Predicted score range: • Pucks and balls are scored in bottom bin only, arrow is not moved: • (5balls+3*3pucks+1)bottom bin(0balls+0Npucks+1)0 bins20 = 15 • Carried balls and all pucks are scored, arrow is not moved: • (5balls+3*3pucks+1)bottom bin(0balls+3*3pucks+1)0 bins20 = 150 • Carried balls and all pucks are scored, arrow is moved: • (5balls+3*3pucks+1)bottom bin(0balls+3*3pucks+1)0 bins24 = 2400

  18. Strategy 2: Puck Lifter • Risks: • Robot falls into scoring bin • Arm misses ‘0’ holes • Opponent disrupts arrow movement • Countermeasures • Rails on bottom of robot to back up over corners • Bump into bins for alignment • Make arrow mover extendable to reach over opponent

  19. Strategy 3: Bulldozer with Minibot • 4WD tracked vehicle with massive driving power • Minibot with stored energy to clamp to bins and move exponent arrow • Special plow to scoop balls from middle

  20. Strategy 3: Bulldozer with Minibot 10 seconds: move up to bin, scooping out balls from the center

  21. Strategy 3: Bulldozer with Minibot 20 seconds: deploy minibot on bins, return while pushing balls and pucks into bin

  22. Strategy 3: Bulldozer with Minibot 15 seconds: disrupt opponent

  23. Strategy 3: Bulldozer with Minibot • Scoring: • If robot achieves proposed strength and maneuverability, scoring will be highly probable • Bottom bin is very easy to score in • Defense: • Robot will be able to push opponents • Most middle balls will be on Bulldozer’s side • Offense: • Tracks will expedite crossing of middle • Minibot can have mechanism to pin opponent’s arrow at ‘0’

  24. Strategy 3: Bulldozer with Minibot • Predicted score range: • Carried balls and pucks are scored, arrow is not moved: • (5balls+3*6pucks+1)bottom bin(0balls+0Npucks+1)0 bins20 = 24 • Carried balls, pucks, and middle balls are scored, arrow is not moved: • (35balls+3*6pucks+1)bottom bin(0balls+0Npucks+1)0 bins20 = 54 • All the balls from the bin and held balls are deposited, arrow is moved: • (35balls+3*6pucks+1)bottom bin(0balls+0Npucks+1)0 bins24 = 864

  25. Strategy 3: Bulldozer with Minibot • Risks: • Minibot is hindered by opponent • Opponent scores before bulldozer is able to cross the centerline • Countermeasures: • Attach minibot quickly to be able to defend • Score pucks and balls quickly; prevent opponent from reaching exponent arrow

  26. Best Strategy: Puck Lifter • Extremely high scores are possible • Driver can always rely on scoring in the bottom bin • Dexterous arm provides best opportunity to move exponent arrow
