Redbot Sumo Shields

thingiverse

As part of Boise Code Camp, the company I work for sponsored a Sumo Bot competition. Everyone used the same hardware; the deciding factor was code alone. The company bought Sparkfun Redbots and I designed and printed the sumo shields that protect them. I configured the Redbot with 2 reflectance sensors in front and one in back, along with an ultrasonic sensor addition. The main purpose of these shields was to safeguard the reflectance sensors while serving as a mount for the ultrasonic sensor itself. Both shields are angled at ten degrees for optimal performance. Front and back shields were designed to print without any support necessary and clip securely onto the Redbot for easy installation or removal when needed. Instructions to reproduce the design are outlined below: The sumo shields were printed using PLA as the primary material, shells at 3 settings, and fill levels at 40%. Print speeds were set to 80/100 millimeters per second. Production times required for each shield include: A front shield requires approximately three and a half hours up to four hours of printing time. A back shield demands roughly one and a half hours of printing time to complete successfully.
