The Diablo is a two-wheeled, self-balancing robot platform by Direct Drive Tech positioned for developers and educators: Naomi Wu tested physical navigation, modularity, and hackability, adding 3D-printed mounts and thermal mods. It includes a Raspberry Pi, a 28 V 6 Ah battery (~4 h), costs about $2,000, but lacks built-in sensors and cannot handle curbs or stairs without custom software/hardware.
