Window Walker

The final project for the Design Nature class was a walker that had to climb up a window using bellows, suctions cups, and one motor. I worked with Mark Cavolowsky, Jeff Dezso and Hossam Banaja to create one of only 3 walkers in our grade that succesfully climbed vertically.

For some reason, Mark and I decided not to use any gears in our design (we were the only team to do this). Instead, I came up with a crazy crankshaft/linkage contraption to transform the motor's rotation into the linear motion required to drive the system. What made it more complicated is that the motion of the bellows needed to be 90 degrees out of phase with the expanding/contracting motion of the device.
