Arduino quadruple robot with simple obstacle avoidance system

After more than 10 years without programming anything, this is my first Arduino project.
A 4 legs robot made out of my wife's hairpins (for legs) and plastic scrap from my son's toy (for the body) controlled by Arduino with 8 mini servos and the infrared sensor. The hardest part is how to balance it while lifting one leg. :slight_smile:
