The ARC BOT was my team's entry into the JHU Freshman Design Competition. It competed through four rounds of competition into the semi-finals. The proposed challenge was to build a device to traverse a 66ft long wire suspended 6ft using only the gravitational potential energy of a 1kg water bottle to propel it. The name is an anagram of the three team member's first and last names.
Our design used a laser-cut stacked acrylic construction, and was extensively tested through numerous prototypes. Highlights of the design include custom-turned PTFE bushings and spacers and a modular gear reduction system which able to be tuned to the specific tension/sag of the competition wire.
