One of the most exciting aspects of robotics is that you can somtimes see beautifully intricate behaviours emerging out of relatively simple mechanisms. Don't get me worng, I love overcomplicating my designs as much as the next engineer, but it's still nice to appreciate simple, elegant ideas every once in a while.
This instructable will introduce some of the simplest and most elegant robotics conepts I have ever seen. The concept came from a book called Vehicles : experiments in synthetic psycology
by a guy named Valentino Braitenberg, and appropriately, robots based off of this concept have come to be known as braitenberg vehicles.
These braitenberg vehicles can be built using nothing but a pair of motos, a pair of sensors, a battery, and a power opp amp, but they are able to move in ways that seem so biological that braitenberg chose to attribute them to emotions.
"Robots that emote? this is not possilbe" you say, and you're probably right, but I've made a short video to demonstrate the robots and show you what I mean.
