This is VEGA this is the second robot i made.The first one is called TOMY and there is a very large distance between them. VEGA's body is two hard disks removed from a old hd unit. He uses a IR coded system to avoid obstacles and for this i used a IR receptor from "PHLIPS components" this is because is very dificult to find the same component from SHARP here. VEGA is able to find a candle inside a room this is because he has light sensors very very sensibles. He uses two servos to navegate and these servos are controlled by a PWM usnit. This robot has a special test device
used to breaks the ccts conection to allow test one by one.
This resource is used once that the role circuit is very complex and if something goes wrong several hours will be spent to find the problem. VEGA can be controllled by TVs remote control. Well if doubts pls pls e-mail me i'll be glat in answer :
PARTS :
Two H-bridgs
Two Futaba servos
One PWM controll unit
One IR coded System using IR closed receptor from "Philips components"
Two light sensor ccts.
One optical coupler cct
