Why it matters
Its developers describe it as the first humanoid robot designed for space work, with five-fingered hands sized like a suited astronaut's.
Real-world use
Ground testbed only; later units were put on a Segway base (2003) and the Centaur wheeled base (2006).

What’s inside
The parts the company has talked about publicly.
- Hands
- dexterous
- Movement
- Stationary · 43 joints
- AI & software
- Autonomous assistant behaviours that hand over and accept tools by reading body language, using a vision-based range silhouette-matching method to track the person and estimate tool pose (Diftler et al., 2003).
- Other details
- Human-scale, anthropomorphic upper body built with DARPA to work with tools and interfaces designed for space-suited astronauts (tether hooks, connectors, soldering). Variants R1A and R1B (portable, 2002) were paired with different lower bodies: a Zero-G leg for handrails, a two-wheeled Segway-based mobility platform (2003) and the four-wheeled Centaur 1 (2006).
