The Magic at your fingertips

Video speaks louder.

LDR

Servo

We had the opportunity to participate n the robotics competition at Cal State Long Beach, where our Robot Sunny showed off his basic skills navigating skills. Although he didn't win first place, we still love our little guy.
He was the only one at the competition to have a servo which rotated the fire sensor we installed on him.

Dizzy Elmo

This is an Elmo Chicken I transformed him into Dizzy Elmo since I programed him to move his head using my Arduino. He lost his skin as the result of a tragic surgery I put him through, yet he still loves to move around specially his head.

 

 

Arduino

This amazing device was the brain of  Sunny, in this tiny chip allowed us to program Sunny so that he was able to move according to the code created n RobotC.

Sonar

An ultrasonic sensor is very useful when you want to be able to identify an object without touching it. This Sonar sensor was used in  our robot Sunny to detect the walls and the candle without bumping into them since it sends out a pulse and waits to hear it back so that it measures how far the object is from it
 .
This was one of Sunny's strongest and reliable sensors, definitely enriched Sunny's performance.

Line Sensor

A line sensor detects the contrast between surfaces like color roughness or magnetic properties. We used a line sensor n our robot Sunny to detect the black line indicating the door of a room in the maze to explore. This sensor enabled Sunny to see the difference between black and white.

Flame Sensor

A flame sensor  is capable of detecting infrared emission of a flame.  A flame emits a low frequency IR light and infrared photo transistors can detect the flame. The output of each detector varies according to the transistor and so the resistor varies accordingly.
