These new mini-drones could revolutionize ground warfare
Many researchers are working to create the next revolution in drones for both war and peace. At the University of Pennsylvania, teams of researchers headed by Dr. Vijay Kumar are making progress on autonomous UAVs. Since they’re autonomous, they don’t need human operators, just the command to begin a task.
The robots created at Kumar Labs are designed for disaster relief and agricultural work, but could change the way the infantry operates, assaulting contested buildings and objectives alongside troops and performing a variety of services.
The first step to moving drones from overwatch in the skies to clearing buildings with squads is getting them into the buildings. The autonomous UAVs created by researchers weigh between 20 grams and 2 kilograms, feature a quad-rotor design that allows hovering, and are nimble, allowing them to fly through small windows or openings.
Of course, if multiple drones are needed on a mission, the drones have to be able to enter the building and move around without interfering with each other or the human squad. UPENN researchers have created different ways for the drones to behave around each other. The copters can simply avoid one another while working independently or on a shared task, follow a designated group leader, or operate in a coordinated swarm as shown below.
Once inside of a building or a village, the drones would get to work. They could move ahead of the squad and create 3D maps of buildings the squad or platoon expects to hit soon.
The little UAVs are capable of lifting objects on order individually or as part of a team. Fire teams that are decisively engaged could quickly request more ammo be brought to their position and see it arrive slung underneath the autonomous drones. Medics could designate a casualty collection point and begin combat casualty care as more supplies are ferried to them. Drones could even be used as suicide bombers, moving explosives to a point on the battlefield and detonating their cargo.
The drones can also construct obstacles. While currently limited to cubic structures made from modular parts, the drones build according to preset designs without the need for human oversight. Platoon leaders could designate priorities and locations of simple construction and the drones would begin completing their assignments. Metal frames could be placed inside windows and other openings to prevent enemy drones from accessing structures. Mines or flares could be placed by drones on the approaches to the objective, slowing an enemy counterattack and warning friendly forces.
Of course, the copters are also capable of completing the traditional drone mission: Surveillance. While not as fast as the larger drones already in use, they could extend the eyes of the drone fleet into buildings. Also, since they can follow preset waypoints, the drones could continuously patrol an assigned area on their own, only requiring a human’s interaction when they spot something suspicious. The drone can even perch on an outcropping or velcro itself to a landing spot, allowing it to turn off its motors and become silent.
Dr. Kumar discussed the robots, the science behind them, and where he hopes to take them during a 2012 TED Talk.
