What’s a Sumobot Jr? Only one of the most awesome robots you can find in a tiny 10cm x 10cm package! Sumobots are competitive robots that are built to push an opponent out of a ring, just like real sumo but without the mawashi.
Watch a minute of this video, and you’ll get the idea.
Those were all autonomous (pre-programmed) and not remote controlled. Amazing! Even more amazing is that you can build one of your own for under $60 with just some basic craft skills (gluing, cutting, and screwing). All the plans and instructions can be found right on the SumoBot Kit website. But when I first visited that site, I was overwhelmed by the amount of material there. So I’ve decided to break it all down into a simple step-by-step guide.
This walk-through assumes you have a Mac computer with a recent version of OS X installed. Instructions for Windows and Linux will be coming in the future.
