collegeBot with dual motor gearbox

thingiverse

This is an improved version of the collegeBot, featuring a dual-motor gearbox upgrade, a larger magnet speaker, a wider push button, and a slightly narrower slide switch. The necessary modifications required minimal changes to the openSCAD files. We're grateful that the original collegebot creator released the SCAD files, rather than just STLs, which has made this project possible. Other parts of the design, such as the side panels and head, remain unchanged from the original. However, one key change was implemented: due to the need to mount two gearboxes together, the top plate, speaker shelf, and bottom plate had to be narrowed down. One notable adjustment is that the bottom plate now consists of a single piece since it fits within our build area perfectly. Here are the revised parts: Gearbox: Pololu.com Product #61 Pushbutton: Amazon.com/B00D7C443C Speaker: Amazon.com/B008999NS Slideswitch: Amazon.com/B007Q9YCAC Notably, we're also utilizing a full-sized Arduino instead of a Nano and mounting it on the bottom plate. A note to clarify that this build is not yet fully complete; printed parts function correctly, but wiring still remains to be done. In addition, exact battery arrangement has yet to be decided upon, though 6 AA batteries are currently under consideration for powering both the Arduino and motor supply, tapping into lower motor voltage requirements.
