I made a mold for injection molding Makey Robot spinning tops a few weeks ago. The tops are designed to be giveaway items at Maker Faire Milwaukee 2016. I plan to injection mold them and hand them out during the Maker Faire. Below you can see a picture of the aluminum mold and a few of the Makey tops that I have molded while testing the new mold.
With all these tops around the house I thought it would be interesting to have a small fighting arena for them. It made sense to model the arena after the BattleBots arena since the tops that will be fighting in it will be Makey Robot tops. Our family loves to watch BattleBots and I thought it would be a fun build just in time for the BattleBots season finally on Thursday (September 1, 2016).
Below you can see a short video of the arena and tops in action (we had a little fun with the intro.) At the end of the video there is a an abbreviated build video.
