DescriptionBack to top
• Designed around the Picaxe 28X1 although many different processors can be used
• Features two standard micro servos for the pan/tilt assembly
• Uses two continuous rotation servos for movement
• No microcontroller is included
The Dagu Mr. General Mobile Robotic Platform does not include a microcontroller. The sensors are simple but effective. The corner sensors are simple voltage divider. The principle is that the phototransistor works much like a LDR (light Dependant resistor). It is based on original LMR robot Bot 08M which was my attempt at a "Start Here" robot using the picaxe 08M processor. More importantly he pointed out that your processor should take two readings, One with the LEDs on and another with the LEDs off. This walkthrough will explain how the sensors work, how the eye works, how the servos work and how the code works.
