It’s GUESTRAVAGANZA! This is a guest post by Steve Wilson of Ohio State University.

I am a senior mechanical engineering student at Ohio State currently and will be graduating in the spring. My girlfriend showed me Wasted Talent a few years ago and I've been reading ever since.

Here is a link to a video of my kinematics and dynamics of machinery project that I did this past spring. We decided to go well beyond what we needed and eventually ended up with an eight legged, radio controlled, walking robot. As far as the engineering goes, we used analytical linkage analysis (basically a bunch of vector loops) which I was able to program into Matlab and generate the foot location and an animation of the linkage. There was also a Solidworks model and animation of the mechanism. All of the acrylic was cut with a CNC LASER cutter. The drive system was taken directly out of an RC tank so that we had separate control of both sides to enable us to turn.

Thanks for taking your time to look at this!

Jam: Wow, way to go TEAM- and thanks Steve for sending this in! Way more ambitious than any of my undergrad projects, I can tell you that much.

Badass!

The Solidworks model shows multiple holes on the drive gears (you probably have a better name for these). Does the spider go faster/climb larger obstacles if you connect to these rather than one on the periphery?

Thanks, we were proud of the Wolfgang. No, we really do not have a better name for the holes if I recall correctly (sorry). The other holes were partly made for aesthetics and a plan B in case of interference.
