The left picture is showing an innovative Ping pong shooter. Unlike other Ping pong shooters using two DC motors to utilize the rotational kinematic energy, we came up with another method by using an elastic rod. The Servo motor will drag the elastic rod and save the elastic potential energy. After releasing the elastic rod, the rod will hit the ball and convert the potential energy to kinematic energy.

We design a mechanism to use only one Servo Motor to put the ball into the shooting base as well as shooting the ball at the same time.
In the picture, if we use the funnel as storing ball device, all the balls will stock in the funnel due to the friction and the geometry of the funnel. As a result, we design a special channel so all balls are able to flow anticlockwise into the inlet.
