Four-legged robot created by Pentagon

Boston Dynamics, which works for Defense Advanced Research Projects Agency (DARPA), has improved its robo-mule. Now it can move faster and quieter.

The robot has built-in surveillance device, which lets it follow a squad's commander like a dog. The new robo-mule doesn't have to be controlled. The new version moves more silently than its predecessor and carries more than 180 kilos of load. It is able to go 32 km without recharge.

It is believed that robot will be used by the military, to carry military equipment and devices. It'll increase squad mobility. The LS3 robot also acts as a mobile charging station for troops to recharge batteries for their radios, tablets or laptops while on patrol. If everything goes well, a full 18 months of tests starting this summer will end with the robot going out on field exercises with the Marines

Robo-mule is not the only robot developed by DARPA. In 2008 this company, which works for Pentagon, created the BigDog, a device that can move in stiff terrain, climb, carry the load up to 55 kg and move with the speed of 8 km per hour. Later on the basis of the BigDog DARPA created Cheetah - the fastest robot in the world. Average speed of the Cheetah is 29 km per hour, and on the special track it can increase up to 80 km per hour.
