Corona chronicles: LEGO egg spinner for Easter

Our EV3 version of the LEGO Easter egg decorating machine.

Like so many others, the Renaud Empire has been staying put at Renaud Manor.

With Easter approaching, I came across a link to directions to build a LEGO egg decorating machine

As soon as I saw it, I knew our half of the Viper Bots (Ludi, Josie and Joseph) would be interested in giving it a try.

A couple of key differences. First, the original instructions used a battery-driven WeDo motor. We have an EV3-based robot named ViperEvie, so we connected an EV3 medium motor to her. It was a little tricky anchoring the medium motor to the LEGO mat, but I figured out a way to do it. Second, we had trouble with eggs rotating and falling, despite trying many adjustments. The thing that worked best for us was adding rubber tires to the back wheels.

We made a video showing the results:
