Fascinating — completely addictive watching these walking along. The video below reminds me of a toddler getting to grips with the opportunities allowed by not running into things.
Here is what Erin has to say about this project: “If you’re interested in humanoids, this seems like a good project to start out with. It’s nice that it uses relatively inexpensive servos. Neat the way it walks with statically balanced frames.”
ROFI is the fifth prototype from Project Biped. It is a self-contained, bipedal robot that uses accelerometer feedback to balance. It has 12 DOF (degrees of freedom) and can walk around while avoiding obstacles using an ultrasonic range sensor. A small Android tablet in ROFI’s head provides the brains and an Arduino Mega provides the hardware interface. All of the designs, instructions, source code, and parts lists are provided for free. ROFI was designed to be easily made by anyone with a low cost 3D printer and an interest in learning about robotics. Check out the FAQ if you have any questions.
