NI002 by Istvan Nagy

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$
