With this brilliant-looking robot, Julius Kanand pays tribute to M-Tron. The black, red, and trans-neon green pieces are all used in perfect proportion to each other to recall the color scheme of LEGO’s old, much-beloved and/or maligned space theme.

There’s some really nice parts usage, too; from the six-sided, rubber-framed dice at the shoulders to the socket wrench-as-antennae. But what I think works best is the minifigure dolly cart used as the shins and feet. The back of the dolly provides a natural vent effect, and the dolly cart is so stable that this robot can stand on one foot! It’s definitely an impressive engineering feet.
