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

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
![Page 11: FEH Robotics Project David Hanson Darren Ng Allen Roe Allen White 11: 30 Gryzbowski](https://reader035.vdocuments.site/reader035/viewer/2022070413/5697bfe41a28abf838cb555b/html5/thumbnails/11.jpg)
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
![Page 12: FEH Robotics Project David Hanson Darren Ng Allen Roe Allen White 11: 30 Gryzbowski](https://reader035.vdocuments.site/reader035/viewer/2022070413/5697bfe41a28abf838cb555b/html5/thumbnails/12.jpg)
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
![Page 13: FEH Robotics Project David Hanson Darren Ng Allen Roe Allen White 11: 30 Gryzbowski](https://reader035.vdocuments.site/reader035/viewer/2022070413/5697bfe41a28abf838cb555b/html5/thumbnails/13.jpg)
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
