Obstacle Avoidance

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. ...

Turns out that rechargeable batteries and the L293D motor controller really slowed things down. Added another battery pack, and with 12 volts the bot actually moves. No smoke coming out of the motors, so all is well….

Batteries almost ran out by the time the bot finally made it trough the obstacle course…Still WIP I guess.

..or rather what is left from a perfectly decent remote controlled tank! http://www.youtube.com/watch?feature=player_embedded&v=ff5dCPZQmjs Comments Comment by Kevin M on 2012-11-14 13:27:13 -0700 Good movement for the tank. Have some questions about fetish’s though… Looks to be a bit of Rubber and Boots to me!

Not really sure why his creator named him “Bad Boy”. There is actually a smiley face painted on the car! Comments Comment by Wagner on 2012-11-18 13:52:25 -0700 He prefers to be called “The Big Boy” to disguise his true personality.

Objectives: Build a robot that is capable of traversing across an obstacle course. The course is configurable to present at least 3 different routes. The Bot has to attempt crossing each of the 3 course setups. The winning Bot will be the one that has completed all 3 courses in the shortest time. ...
