Red Bull Challenge 2013


Red Bull's yearly challenge event may sound grueling to some: a 72 hours spent hacking away at a piece of art with little to no sleep. For us, it's better than a vacation. For the 2013 Red Bull Challenge qualifier the team built a six foot robotic arm that spins around a phosphorescent canvas. As the arm moves across the canvas ultraviolet LEDs flash on and off to burn a temporary glow in the dark image onto the canvas. A website allows the public to send drawings or images to the arm in real time.
