Intended for intermediate robot builders with a basic understanding of Java, this hobby book introduces RS-22 serial communication, and provides Java class examples for moving wheel robots, robot arms, and legged robots. The Java architect uses BASIC Stamp to communicate with sensors, describes different approaches to speech synthesis and voice recognition through a PC, and explains how to program a robot to navigate both indoors and outdoors.
