Remember DARPA’s BigDog? You know, the terrifying, four-legged robot that won’t fall over when kicked or when walking on ice and snow. Well, DARPA and Boston Dynamics (the guys who are also working on this) are testing an upgraded version of the dog that will carry 400 pounds of gear for more than 20 miles without a refueling.
The latest version of the robot, called the Legged Squad Support System (LS3), will use “vision sensors” to lock onto dismounted soldiers and follow them in the field (like a loyal puppy, too bad it reminds me of the Terminator) and autonomously navigate around obstacles in its path. Heck, the damned thing is even expected to respond to soldiers’ voice commands, like “come”, “stop” and “sit.” Oh and if that’s not enough, it will serve as a walking battery charger for troops’ electronics.
I will say one thing, it’s going to have to get a lot quieter to accompany some infantry patrols.
Read what DARPA has to say about its new toy and then click through the jump to watch a video of the LS3:
Recently the LS3 prototype underwent its first outdoor exercise, demonstrating the ability to follow a person using its “eyes”—sensors that allow the robot to distinguish between trees, rocks, terrain obstacles and people. Over the course of the next 18 months, DARPA plans to complete development of and refine key capabilities to ensure LS3 is able to support dismounted squads of warfighters.
Features to be tested and validated include the ability to carry 400lbs on a 20-mile trek in 24-hours without being refueled, and refinement of LS3’s vision sensors to track a specific individual or object, observe obstacles in its path and to autonomously make course corrections as needed. Also planned is the addition of “hearing” technology, enabling squad members to speak commands to LS3 such as “stop,” “sit” or “come here.” The robot also serves as a mobile auxiliary power source— troops may recharge batteries for radios and handheld devices while on patrol.
DARPA seeks to demonstrate that an LS3 can carry a considerable load from dismounted squad members, follow them through rugged terrain and interact with them in a natural way, similar to the way a trained animal and its handler interact.
“If successful, this could provide real value to a squad while addressing the military’s concern for unburdening troops,” said Army Lt. Col. Joe Hitt, DARPA program manager. “LS3 seeks to have the responsiveness of a trained animal and the carrying capacity of a mule.”
The 18-month platform-refinement test cycle, with Marine and Army involvement, kicks off this summer. The tests culminate in a planned capstone exercise where LS3 will embed with Marines conducting field exercises.
LS3 is based on mobility technology advanced by DARPA’s Big Dog technology demonstrator, as well other DARPA robotics programs which developed the perception technology for LS3’s “eyes” and planned “ears.”
