Why it matters
Demonstrated Brooks' 'subsumption architecture': insect-like walking emerging from simple layered controllers with no central planner.
Real-world use
None; NASA JPL micro-spacecraft workshop motivated the project

What’s inside
The parts the company has talked about publicly.
- Movement
- Walks on legs · 12 joints
- How it runs
- Fully autonomous. It walked over rough ground using distributed sensor-to-motor control and followed people detected by infrared sensors.
- Actuators & motors
- 12 position-controllable model-airplane servomotors (two per leg); 12 DoF.
- Sensors & vision
- 12 force sensors, six pyroelectric infrared sensors, two inclinometers and two touch whiskers; each leg sensed its own obstacles.
- Compute
- Four on-board 8-bit microprocessors on a 62.5 kbaud token ring; 1 KB RAM and 10 KB EPROM in total.
- Battery & power
- Three silver-zinc batteries.
- AI & software
- Rodney Brooks's subsumption architecture: eight layered behaviours (stand up, walk, force balancing, leg lifting, whiskers, pitch stabilisation, prowling, steered prowling) with no central planner.
- Other details
- About 1 kg and 35 cm long. Now at the Smithsonian National Air and Space Museum.
