For The ASICS World Series of Beach Volleyball we wanted to give people the opportunity to experience what it feels like to go up against three-time gold medalist Kerri Walsh. So, we created Kerri’s robot twin, the Kerri Cannon, a high-velocity, high-precision volleyball launcher designed to simulate the power and accuracy of Kerri Walsh. We also let fans at home in on the action by allowing them to control the Arduino-powered cannon live using a custom web application.
