The infill that we used for the drop test was a small square pattern that stays unchanged throughout the print. Evidently, this wasn’t strong enough to handle the stress of the weight of the robot and...Read More

The time is drawing near that the crew heads off to Canada! Since my last update on the wheels, we’ve made some slight changes to the original design and added an entirely new wheel design.

Using Inventor, I started out with a basic sketch of the Hub outlining the main body including holes for the servo. After extruding the sketch for...Read More
