PulleyBot - You can now make a Pulley Driven 3D Printed Robot

[Eddie]

Alex Crease loves building things, and as one of four students who run the 3D printing space at Olin College of Engineering, he says he's constantly looking for new ways to use the 3D printers. Among the things he's discovered as to those new ways to use 3D printers, Crease has now built what he calls the PulleyBot, a simple and single actuator 3D printed toy with a transmission made entirely of pulley systems and belts. You can read the whole story here: http://3dprint.com/89121/3d-printed-pulleybot/
Below is a photo of the PulleyBot:

looks like fun - he could have printed the belts as well.
And if he;d made it clockwork he could have printed the entire thing :-)
