Walking robots are often slower than driving robots, but they have the improtant advantage that they navigate over terrain, while driving robots require a more or less flat surface. The simplest case of a walking robot uses 6 legs, sinve this allows to implement a gait that always lifts up and repositions 3 legs, while the other 3 legs remain on the ground, providing a solid balance. Such a robot does not need to actively balance, as is required for our balancing and biped walking (android) robots. For details see the book "Embedded Robotics".
The mechanics and sensor electronics has been individually constructed around the EyeBot controller.
See walking robot videos.
