KSR4 – "ESCAPE" ROBOT KIT

Fig. 1

1. Introduction & Characteristics

Thank you for buying the KSR4! Read this manual carefully before bringing the device into use. The KSR4 works just like an A.I. robot. It never fails to find its way out of a maze. The Escape Robot uses 3 infrared emitting diodes and 1 infrared receiving module to send and receive signals and detect obstacles. The Escape Robot's built-in microprocessor enables it to "think" on its own: it gathers and processes information about its environment, which enables it to avoid any obstacle. The Escape Robot moves around on 6 legs. The Kit comes complete with 2 sets of differently designed legs, which move in their own distinct way. Fun and excitement are guaranteed. The KSR4 requires four 1.5Vdc AAA-batteries (not included). Apart from the batteries, you will also need a pair of long-nose pliers, a soldering iron, a diagonal cutter, a screwdriver, a soldering iron and a length of solder wire.
