Mechanical System Design

Timeline: 5 weeks

Team: Katrina Liou, Kameron Robinson, Matt Murphy

Process: PLA, Tamiya 72001 gearmotor kit, shafts and ball bearings.

Project Overview: Our robot is designed to move up an I-beam as fast as possible while carrying an offset load. We used a design process that blends intuition, concept generation, back-of-the-envelope analysis, computational analysis, models of motors and gears, design for mass efficiency, empirical testing, and technical writing, iteratively and with appropriate balance.
