Zeno

A small walking boy robot with an expressive face made of Hanson's Frubber skin, used for research on human-robot interaction and on autism diagnosis and therapy. Its 36 DoF include 8 in the face, and its design was inspired by the child android David in Brian Aldiss's story 'Supertoys Last All Summer Long'.

What’s inside

The parts the company has talked about publicly.

Movement
Walks on legs
Actuators & motors
Later research version: 36 DoF (arms 12, legs 12, waist 1, neck 3, face 8) using Dynamixel RX-64 servos in legs, hips and shoulders, RX-28 servos in the waist, and Hitec HS-65MG plus Cirrus micro servos to move the Frubber face. The 2007 prototype was described with more than 28 motors.
Hands
Small hands with grip-load sensors (later version).
Sensors & vision
Later version: an HD camera in each eye, 3-axis gyroscope, accelerometer and compass, 21 joint load and 30 joint position sensors, cliff, ground-contact, infrared and foot-bump sensors, and three microphones.
Compute
Later version: 1 GHz Vortex86DX CPU with 1 GB RAM, Wi-Fi and Ethernet. The 2007 prototype was driven wirelessly from an ordinary PC running a variant of Massive Software's AI.
Battery & power
Two 18.5 V lithium-ion packs, about 1 hour of operation (later version).
Materials & build
Face of Hanson's patented Frubber skin-like elastomer over a plastic and aluminium body.
AI & software
Linux (Ubuntu); 2007 demo used Massive Software's decision-making AI; later Robots4Autism versions added NSF-funded CompuCompassion emotion modelling for therapists.
Other details
Sizes differ by version: the 2007 prototype was reported at 17 inches (about 43 cm) and 6 lb.5 cm and 6.5 kg. Styled after Astro Boy. Later commercialised for autism therapy through RoboKind's Robots4Autism programme.
