Boston Dynamics have come up with an improved version of a robot called AlphaDog that, according to DARPA manager, represents a mix of a pack mule and intelligent animal. It is worth mentioning that the weight an average soldier is able to carry varies between 60 and 100 pounds. In contrast, the AlphaDog, also called L3 (Legged Squad Support System) is able to carry up to 400 pounds and register a range of up to 20 miles before needing refuel. Currently the robot is being tested, but researchers have already managed to teach it a couple of new tricks. Thus the machine is able to autonomously follow a human leader, and understand commands from the user that holds a control pad. The plans for the near future include significant noise reduction and voice command recognition.
