Mech-Dickel Robotics has designed a beautiful quadruped robot dubbed mechDOG, which utilizes a dozen servos for motion. This gives each leg three degrees of freedom, allowing the cat-sized beast to travel a meter in 8.46 seconds. While it won’t break any speed records, creating a walking motion on this sort of unstable platform is an impressive feat in itself.
mechDOG is controlled by an Arduino Uno, while a Lynxmotion Smart Servo Adapter Board interfaces with the servos themselves. The device is remote-controlled via an RF unit, though it does have a pair of ultrasonic sensors that presumably could be used for obstacle avoidance.
You can check it out in action in the videos below, looking sharp in its yellow-finished aluminum sheet metal chassis.
