Over the years I have been fascination with robots. Sci-fi authors have been writing about them for years. Many people are working hard to implement robots in everyday life. Their working everyday to make life easier for everyone around. The use of robotics is one way they are doing this. Evidence of robotics are all around us. We have Motion detector lights for our homes, bomb crawlers that save lives, and seekers that seek out injured people in desasters. There are vast amounts of robotic devices in the world. I am going to focus on one kind. IR Sencored and mobile robots.
Today I would like to introduce IR (Infrared) technology. Infrared sensors are playing more intricate parts in everyday life as we turn the century. They are found in remote controls, car sensors, and wireless robots. I built a self-guiding robot equipped with a phototransistor, to show how IR sencors work in robots.
The phototransistor will be triggered by the LED (Light Emitting Diode), when it is near an object. The motors will stop for a second. Then one motor will rotate backwards while the other moter begins rotating forward, pausing every two seconds. The motors will run in the same direction again when the LED no longer reflects off the object in front of it.
My goal is to demonstrate how the robot is built, explain why it works, and give some practical applications for a mobile IR robot.
I would like to bring practical robotics to everyone.
