M.E.G.A.T.R.O.N. (Maneuverable Energy Generating

Appendages To Relieve Operating Necessities)

Evolution of Design

ORIGINAL MODIFIED FINAL

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

Final Competition Results

Awarded 2nd most innovative design

Rationale for Mass ProductionMEGATRON is innovative

Dual-purpose appendagesWe believe the competitions are deceiving indicators what our DROID is capable ofSeveral 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
