Shockwave

Overview

In Summer 2010, Team 254 decided to build a T-Shirt Shooting Robot to be used for promotional events. After two months of hard work, our robot “Shockwave” debuted at a spirit rally at our school, Bellarmine College Prep in San Jose. The robot was received very well and was loved by the students at the rally.

Team 254 uses Shockwave to promote the team and its sponsors. We bring the cannon to team and school events as well as sponsor events.

Detailed information about the design and build process as well as the cannon’s technical specifications can be found below.
