Robots are going to change the way we do everything in the future. Take the LS3 (Legged Squad Support System) robotic cow: it teams up with a squad of marines and carries their equipment and supplies for them. It does not get tired, and you don’t have to feed it either. It can go places that conventional vehicles may not be able to easily. The Marine Corps Warfighting Lab has been testing the LS3 and GUSS. Don’t expect to be able to get your hands on one of these robots anytime soon though.
