Everyone gets busy. Sometimes, our four-legged friends get neglected. Here is a prototype dog walker. It follows your dog and keeps it on the sidewalk and away from water, grass, fire hydrants, and other people.
It is built on an AVR platform. It uses a CMOS camera to detect colors. A potentiometer is used to tell what angle to turn. A ultrasonic range finder detects obstacles. A push-button switch detects forward movement.
