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: (0 balls +0k pucks +1) bottom bin (5 balls +0N pucks +1) 0 bins 2 0 = 6 –No balls from the bin, only held balls are deposited, arrow is moved: (0 balls +0k pucks +1) bottom bin (5 balls +0N pucks +1) 0 bins 2 4 = 96 –All the balls from the bin and held balls are deposited, arrow is moved: (0 balls +0k pucks +1) bottom bin (20 balls +0N pucks +1) 0 bins 2 4 = 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: (5 balls +3*3 pucks +1) bottom bin (0 balls +0N pucks +1) 0 bins 2 0 = 15 –Carried balls and all pucks are scored, arrow is not moved: (5 balls +3*3 pucks +1) bottom bin (0 balls +3*3 pucks +1) 0 bins 2 0 = 150 –Carried balls and all pucks are scored, arrow is moved: (5 balls +3*3 pucks +1) bottom bin (0 balls +3*3 pucks +1) 0 bins 2 4 = 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: (5 balls +3*6 pucks +1) bottom bin (0 balls +0N pucks +1) 0 bins 2 0 = 24 –Carried balls, pucks, and middle balls are scored, arrow is not moved: (35 balls +3*6 pucks +1) bottom bin (0 balls +0N pucks +1) 0 bins 2 0 = 54 –All the balls from the bin and held balls are deposited, arrow is moved: (35 balls +3*6 pucks +1) bottom bin (0 balls +0N pucks +1) 0 bins 2 4 = 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
