SDR-3X

Hardware

SDR-3X's measurements are: width = 22 cm, height = 40 cm, depth = 14 cm, weight = 5 kg

SDR-3X has two 64 bit RISC CPUs, each with 32 MB of DRAM. They are split between two enclosures on it's back because of the articulating waist. The upper CPU controls autonomy and video/audio processing, and the lower CPU handles walking and movement.

The battery is a nickle-metal hydride battery.

The head has a 180,00 pixel 1/5th inch CCD color camera, an infrared distance sensor, one microphone where each "ear" would be, and a speaker where the "mouth" would be.

ISA (Intelligent Servo Actuator)

Software

The operating system that runs on SDR-4X is Sony's own custome real-time OS named "Aperios".

SDR-3X uses the OPEN-R architecture that is used in their AIBO robot dogs. It can walk at a speed of 0.9 km/h, and turn 90 degrees per step.

It can also recognize around 20 words.
