LEGO builder Markus Rollbühler returns to the Brothers Brick with WheelSpin, a mono-wheel utility drone. Part of the year-long Mech Monday project, WheelSpin is a self-balancing mono-wheel drone with multiple configuration options. The base of the mech is filled with great texturing, with greebles including Technic chain links, hammers, and space blasters. The lime green of the armor creates a nice contrast to the transparent blue of the eye sensor, blade shield, and the shock absorber at the base of the leg.

The industrial version shown here comes complete with a grabbing claw and saw blade — advertised as “perfect for any kind of industrial job.” Personally, I see it as greeter at Wal-Mart in a very dystopian future. Your mileage may vary.
