This volume focuses entirely on building the inexpensive, remote-controlled robot, The "Questor". The book is illustrated with step-by-step, detailed photographs of each stage of the assembly process. No advanced electronic or programming skills are required, making the book suitable for first-time experimenters. The emphasis is on the techniques needed to build the robot, rather than on the theory of robot design. Easy-to-read wiring diagrams are included, with beginners in mind, and the book also features a complete parts list, including tips on where to find inexpensive parts and components.
