Daisy – an Arduino autonomous obstacle avoidance robot

By | July 13, 2014

Daisy is an old “Discovery Kids” projection alarm clock turned into an autonomous obstacle avoiding bot. The brain is an Arduino Mini. Two small servos, modified for continuous rotation, are used for a differential drive and a combination of 3 infrared sensors (under the “skirt”) and 1 HC-SR04 ultrasonic sensor (the “eyes”) detect obstacles. I used the built in piezo buzzer for the alarm clock to play some basic tunes and sounds when power is turned on.
