I picked up the Sunfounder Quadruped Robot Kit a couple of days ago out of frustration more than anything else. I’ve been hitting a few walls lately with the drive system on my Viking battle robot. The differential track steering has proven to be a real drag (pun intended). I needed a distraction so went for something I could tinker with that 1) didn’t use wheels or tracks and 2) had pictured directions of a working design (it’s exhausting building stuff from scratch). The Sunfounder Quadruped is an open source, Arduino based crawling insect that you assemble and programme yourself. It’s a pretty cool, attention grabbing technology demonstration and I’m always looking for something like this to inspire students at school.
