Goo. Basic Stamp II powered robot. Uses 4 bit radio control, which is decoded to 8 seperate control functions. FORWARD, REVERSE, LEFT, RIGHT, HEAD RIGHT AND LEFT, and a couple other buttons for various sound effects, schematics are available on web page. A video camera/transmitter is mounted in Goo's head, which allows him to be driven remotely. The receiving 5" black and white TV has the video in, and the robot drive transmitter controls are built inside for a portable hand-held controller unit. Goo can be controlled and driven by TV when he is in another room in the house! Works great! see for more details on construction and programming. Rough cost estimate: $50 for BASIC STAMP II STAMP Controller board - Homemade $24 - 3 model airplane servos, 2 modified, 1 not. $25 - 12v rechargable battery pack - Homemade. $50 - 4 bit radio trans/rcvr $99 - X10 video camera trans/rcvr - modified. $30 - Goo Shell, see web page for details. $7 - Black and white TV, on closeout at AMES. Misc junkbox parts, led's, switches, wheels, etc. Problems encountered: Not much really. Originally did not have enough voltage in main power supply battery (7.2V) to drive everything (mostly camera) had to increase to 12V. Cramming everything into 5" TV was fun. Email:
