Team SMAC’s Design Experience Design Process, Successes, and Failures

Introduction Steve Dora Mark Garringer Jon Arndt Cheryl Fang

Design Overview Lego MINDSTORMS Design a robot to compete in “Intergalactic Triathlon” Timed obstacle race Basketball free-throw Heavy-pushing Victory dance Optical and touch sensors Alignment

Competition Surface Schematic

Basketball Goal Structure and Dimensions

Creativity Process Post-IT notes, brainstorming Pugh Matrix Trial-and-error

Results Timed obstacle race: 23 seconds Basketball free-throw: 33% Heavy pushing: 120 cm Victory dance: rocks back and forth, spins, free-throw arm, sound

Lessons Learned Trial-and-error Good team dynamics Implement Pugh Matrix for each subsystem Focus more on accuracy instead of auto-load Started programming earlier

Conclusion Follows guide path Successfully avoids all obstacles Low free-throw accuracy rate Pushes heavy object full length Unreliable system

Recommendations More time and parts in order to increase performance of robot Implement auto-load Smoother movement while following guide path More accurate shooting arm

Future PDS RoboGolf Strongman Competition Tug-O-War Battle Bots Incorporate ramp Track meet
