This is Potatochip-E, a modular Chip-E based on Mr. Potatohead from Toy Story! https://youtu.be/OkA6rwScdbA We're two Creative Technology students from the Netherlands who are eager to study how humans react to robots and if it can influence their behavior. As poor students, we thought entering this contest in the hope of winning would be a great opportunity. When seeing the Chip-E contest, we brainstormed different designs, but eventually had the idea of creating a Mexican design with a large sombrero that could hold some chips. We wanted to make it modular so people could create their own designs to add to this framework. Our first example is the Mexican design, which we decided to build. We made the design modular by reusing pins from Tbuser (https://www.thingiverse.com/thing:10541). The pins have two sides - one 'normal' side and one anchor side with 90-degree corners that lock into place. This makes printing parts like guitars easier, and the pins stronger because they can be printed in a specific direction. Aside from modularity, we also made Chip-E rounder to make it appear more friendly and less robotic. In other designs, adding roundness instead of a square shape often increases the size of the robot. We ensured that our design wouldn't increase in volume by using the extra space in the original design to round out the corners while keeping room for cables. To help those who want to add pinholes into Chip-E, we've included a pinholemaker with negative space for both holes in Chip-E and custom designs. The pinholemaker already has a 0.3mm tolerance so that the pins fit perfectly.
