Introduction  Team Members Roles  Team Name Team ρBOT  Robot Name M.E.G.A.T.R.O.N. (Maneuverable Energy Generating Appendages To Relieve Operating Necessities)

Evolution of Design ORIGINALMODIFIEDFINAL

The “Kickstand” Construction: Two Futaba Servo Motors (Not Hacked) Two Modified Cal Adapter for Servo Heads Two ½” Acrylic Legs Uses: Start Within 9” x 9” Footprint Lower and Raise Forks/Bumper Accordingly Raise SIGNAL Hanger Up to Signal Beam

Plans for Competition  Path Strategy Paths shown are dependent where the DROID is positioned. Paths identical in distance, but are mirrored.

Plans for Competition cont. Kickstand used to: Raise SIGNAL Release DUMPSTER Meet dimension requirements Fork used to: Lift DUMPSTER Turn CRANK

Results  Individual Competition 3 performance tests  Course of actions Results  Score  Seeding placement  Resulting alterations made

Results cont.  Final Competition Results Awarded 2 nd most innovative design

Rationale for Mass Production  MEGATRON is innovative Dual-purpose appendages  We believe the competitions are deceiving indicators what our DROID is capable of  Several unfortunate circumstances regarding the competition Shaft encoders GPS  These problems are fixable before production

Summary/Conclusions  Overview  Final alterations made  Plans for production

Summary/Conclusions  Brainstorming Hand-drawn sketches Autodesk Inventor drawings  Testing/Refinement Drive-train calculations IC Code Chassis/appendages modified numerous times (Fork, SIGNAL holder, kickstand etc.)  Final test before competition was successful 64 out of 80 point run

Summary/Conclusions  Results Individual Competition  10, 5, 10 point runs  Seeded into a play-in bracket Final Competition  8 point runs  Failure most likely related to the GPS beacon or code controlling GPS beacon

Conclusions  MEGATRON displayed consistent success during tests preceding the Final competition Reliably picked up/deposited DUMPSTER in correct bin Turned CRANK 360˚+ on majority of runs Ascended RAMP every run when picking up DUMPSTER Pressed SUBWAY button on more than half of test runs Returned to CHARGER station and hit stop button on nearly every test run

Conclusions  MEGATRON did not duplicate success in Final competition due to faulty navigation Turned into wall and got stuck  Final alterations Modifying code to average GPS values to help with navigation We believe this would result in an extremely successful DROID
