Thirty-four of the 36 students who make up Clinton High School’s First robotics team cluster on the full-size practice playing field they built in a Nypro corporation warehouse. Their near-winning entry, Gael Force, stands in the center. Even at the high school level, robots don’t come cheap: Of the $3,500 robot-building budget to which all teams are limited, Clinton devoted $3,231 to Gael Force. They spent another $2,500 to create the indoor practice field.
