Xavier has demonstrated itself as valuable research tool. Using Xavier as a prototype, Real-World Interfaces, Inc developed a complete robot on a B21 base for us.
Amelia has substantial engineering improvements over Xavier.
It has a top speed of 32 inches per second, while improved integral dead-reckoning insures extremely accurate drive and position controls. The battery life is six hours, and are hot-swappable, so Amelia does not have to be powered down to change them. A 75Mhz 486 laptop acts as onboard console. All these are inter-connected by an internal 10M Ethernet, and to the world via a 2MBs Wavelan wireless system. Sonar and infrared sensor arrays ring the robot, mounted on Smart Panels for quick and easy access to internal components.
