A robot to complete 4 tasks (dispensing payloads, securing objectives, reaching levers, and moving) in a course wide, head-to-head style competition. I was responsible for the frame, sheep, fish/eel, drivetrain, and bucket subsystem design and the integration of all subsystems.
Our design philosophy centered around reliability and modularity.
Reliability
Rationale for Reliability
all tasks needed to be complete several times
a bad run can heavily impact your score (penalties and disqualification)
Requirement: Complete each task 5 out of 5 times consecutively in a full competition environment.
Implementation
precise and tunable power sources
pneumatic pistons
motors
precise manufacturing/assembly
3D printing
assembly jigs
alignment slots
Results
Drivetrain: 5/5
Sheep: 4/5
Scissor Lift: 5/5
Fish/Eel: 2/5
Modularity
Rationale for Modularity
all subsystems are independent
root cause analysis is easier
integration is easier
iteration is easier
Requirement: All repairs and changes must not require the disassembly or alteration of other subsystems.
Implementation
modular frame
aluminum extrusion rails
adjustable components
switch placement
wheel placement
sheep subsystem height
fish/eel angle
scissor lift height
Results
all subsystems except drivetrain and the frame were fully independent
adjustable within the constraints of the fame
no dissemble of other subsystems required
