Robotany is a collaborative of Jill Coffin, John Taylor, and Daniel Bauen to combine nature and robotics. Breeze, the first installation of Robotany, is an ambient robot inhabiting the body of a japanese maple. Breeze can visually sense and react through 360 degrees, allowing her to reach out to you and others whenever you are near. This is not a dancing bush, the motion is subtle and artistic, and at the same time, surreal.

Both cleanly powered and built from 2 recycled bicycles, scrap steel and wood, leaking 5 gallon water jug and a lacross stick, our pedal powered tennis ball launcher allows players varying in skill levels to practice to be better at both tennis and cycling. The launcher is towed to the court on its built-in bicycle trailer. A bike is secured to it and functions to drive the device. Pedaling the cycle as one would on a trainer drives the two launcher wheels. The cyclist then aims and pulls the lever to launch balls to the hitter.
