How is a tiny braitenberg vehicle robot made? by Alexander Weber

tiny_robot It weighs 17 gramms, is driven by two pager motors, powered by a small lipo cell and controlled by an 8-pin ATtiny25V. Pretty isn’t it? After reading this post you can build this amazing robot on your own. First, i want to explain what exactly braitenberg robot is?

Braitenberg vehicle : A Braitenberg vehicle is an agent that can autonomously move around. It has primitive sensors (measuring some stimulus at a point) and wheels (each driven by its own motor) that function as actuators or effectors. A sensor, on its simpler form, is directly connected to an effector, so that a sensed signal immediately produces a movement of the wheel. Depending on how sensors and wheels are connected, the vehicle exhibits different behaviors (which can be goal-oriented). This means that it appears to strive to achieve certain situations and to avoid others, changing course when the situation changes.^{[1] Devamını gör…}
