LS3 is a dynamic robot designed to go anywhere Soldiers and
Marines go on foot. Each LS3 will carry up to 400 lbs of gear and
enough fuel for missions covering 20 miles and lasting 24 hours. LS3
will not need a driver, because it will automatically follow a leader
using computer vision or travel to designated locations using sensing
and GPS. The development of LS3 will take 30 months, with first walk
out scheduled for 2012. The development of LS3 is being funded by
DARPA and the US Marine Corps.
