Motor Actuated aluminum paddle – Blind Juggler


The Blind Juggler is a robot that juggles or bounces balls in a controlled manner without any sensory input. The two main parts of the Blind Juggler are an aluminum paddle and a linear motor that actuates the paddle.

It is doing this based purely on pre programmed math. There are no sensors telling it to make any adjustments. While we could envision this functioning, we would never have expected it to be as stable as it is.

Video used for measuring impact locations of the ball on the Blind Juggler. The impact is detected by a microphone and the red LEDs light up. Then, the frame where the LEDs light up is analyzed and the ball impact location and the paddle center are extracted. The measured data allowed us to assess the juggling performance and identify the process noise introduced into the system.
