Overview

The "real household robot" of the group, with two arms at counter height, a movable head, and room for a power station and a laptop. It's a research kit, though. It comes half-assembled, the docs are aimed at Ubuntu, speed and runtime are undocumented, and it is tall and top-heavy over thresholds. Best suited to manipulation research.
