Abstract: A micro lock valve includes a cylinder forming an air chamber. One part of the cylinder is provided with an inlet port and an outlet port which communicate with each other through the air chamber, and the other part is provided with an exhaust port communicating with the air chamber. The micro lock valve also includes a plunger slidingly traveling in the cylinder, blocking up one of the inlet port or the exhaust port, and formed with a female screw thread in a traveling direction of the plunger. The micro lock valve includes a driving shaft having a male screw thread mating with the female screw thread and a driving motor rotating the driving shaft forwardly and backwardly. Accordingly, the micro lock valve maintains a normally closed state and a normally open state without consuming a large amount of electric power and is driven by low electric power for a long period of time. Further, the micro lock valve needs relatively low electric power to drive a number of the micro lock valves, and decreases noise due to an operation thereof.

It is an aspect of the present invention to provide the walking robot and the method of controlling the same, which reduces development and manufacturing costs of the walking robot and allows non-specialists to easily participate in the development. The walking robot includes a plurality of legs. One or more sensors are mounted on soles of each of the legs to detect whether the soles of each of the legs are in contact with a ground during locomotion. The walking robot performs the locomotion according to a locomotion pattern composed of a plurality of locomotion cycles, and proceeds from a current locomotion cycle to a next locomotion cycle after determining whether the current locomotion cycle is stable using detection results of the sensors.
