LS3 Follow Tight (mobile, semi-autonomous legged robot)

December 21, 2012

For the past two weeks, researchers from DARPA’s LS3 program have been testing the Legged Squad Support System (LS3), a four-legged robot.

They have demonstrated new advances in the robot’s control, stability and maneuverability, including “Leader Follow” decision making, enhanced roll recovery, exact foot placement over rough terrain, the ability to maneuver in an urban environment, and verbal command capability.

This video shows the robot negotiating diverse terrain including ditches, streams, wooded slopes and simulated urban environments. The video also shows the map the LS3 perception system creates to determine the path it takes.

The LS3 program seeks to demonstrate that a highly mobile, semi-autonomous legged robot can carry 400 lbs of a squad’s equipment, follow squad members through rugged terrain and interact with troops in a natural way similar to a trained animal with its handler. The robot could also be able to maneuver at night and serve as a mobile auxiliary power source to the squad, so troops can recharge batteries for radios and handheld devices while on patrol.
