MOST IMPORTANT (60)
Speed to acquire floppies (keep opponent from scoring) (10)
-Passive vs. active [4 for passive, subtract one for each DOF]
-Speed of acquisition of floppy (first contact to ready for next floppy) [6 for <3 sec, -1 for every second above]
Hold large # of floppies (10)
-Number of floppies [0.5 per floppy held]
-Segregation of alliance vs. opponent floppies [2 is yes]
Durability (10)
-Doesn't trash itself [0 points]
-Withstand impact with field borders [2 points]
-Withstand impact with puck [3 points]
-Withstand impact with other robot [5 points]
Get on top of puck (10)
-Speed [1 point in <20 sec; 2 in <10 sec]
-Stability [1 for each stabilizing feature]
-Accommodate alliance partner [2 points if leave open 30x36]
-Denial of opponent [2 points for each active mechanism]
Quick/easy assembly (manufacturability) (10)
-Number of DOFs [start w/ 4; 3 DOF freebie; -1 for every after that]
-Kit/SPI vs. custom [start w/ 4; -1 point for each manufactured gear or major component]
-Ability to change gearing [2 points]
Speed of base (10)
-Top speed [1 point per ft/sec up to 8]
-Torque/speed change capability [2 points]
-Rate of rotation
NICE TO HAVE (35)
Lift floppies above 8 feet (7)
-Number of floppies [0.5 point per floppy]
-Speed [1 <20 sec; 2 <10 sec]
-Motion precluded after raising? [-1 point if motion precluded]
-Robustness [-1 if can't tak a hit]
Power/torque (for pushing/pulling) (7)
-Ability to push [2 points]
-Turning while pushing/pulling [1 point]
-Ability to pull [2 points]
-Force level [>25 lbs--1 point; >50 lbs--2 points; >75 lbs--3 points]
Stability/recoverability (7)
-CG height [4 points <6", -1 point for every 6" above that]
-Outriggers (outside 30x36) [2 points]
-Self-righting [3 point]
Maintainability (7) -- SUBJECTIVE MEASURE -- Strategy Team determines
