My name is Istvan Nagy i am 19 years old,and student currently preparing for university studies. You can see the description of my first robot. It is entirely automatic, operated by buttery power. (without microcomputer) The following is a description of how it works: It continually moves forward until it reaches obstacle, that the opticle sensors sens.Theobstacle can be something standing in front, or it on the edge of the table. After it stops, it moves backwards, turns, and about 1 seconds later continues forward. The sensation happens on repelled signal, which is sensed by phototransistors. The signal is given on a 25KHz frequency. The entire interior i planned and prepared about 2 months. Cost:30$ Parts used: - 31 transistors - 10 diodes - 55 resistors - 18 capacitors - 1 infra LED (200mW/25mW) - 2 DC walkman-motor - 5 AAA-battery Email:
