Aggressive Quadrotor Maneuvers Are Totally Nuts

Every once in a while, we get to see a video of a robot doing something that makes us think "OMG WTF THAT’S WICKED CRAZY IMPOSSIBLE!!!" And then, we remember that crazy stuff is entirely possible, because we’re talking about robots, and we have to stop thinking about what is and is not possible in terms of human capabilities.

This is one of those videos:

I don’t have much more info for you than what’s in the video, unfortunately, but it does look like these maneuvers (while obviously autonomous) are currently restricted to an area with a whoooole bunch of sensors that can tell the robot where it is with an accuracy (and frequency) that’s probably pretty impressive.

If you remember, we’ve seen both autonomous acrobatics and autonomous landing on slopes by UAVs, but nothing like this… The precision of these maneuvers is just totally completely nuts.

Robot with threads near a fallen branch

RoMan, the Army Research Laboratory's robotic manipulator, considers the best way to grasp and move a tree branch at the Adelphi Laboratory Center, in Maryland.

“I should probably not be standing this close," I think to myself, as the robot slowly approaches a large tree branch on the floor in front of me. It's not the size of the branch that makes me nervous—it's that the robot is operating autonomously, and that while I know what it's supposed to do, I'm not entirely sure what it will do. If everything works the way the roboticists at the U.S. Army Research Laboratory (ARL) in Adelphi, Md., expect, the robot will identify the branch, grasp it, and drag it out of the way. These folks know what they're doing, but I've spent enough time around robots that I take a small step backwards anyway.

This article is part of our special report on AI, “The Great AI Reckoning.”

The robot, named RoMan, for Robotic Manipulator, is about the size of a large lawn mower, with a tracked base that helps it handle most kinds of terrain. At the front, it has a squat torso equipped with cameras and depth sensors, as well as a pair of arms that were harvested from a prototype disaster-response robot originally developed at NASA's Jet Propulsion Laboratory for a DARPA robotics competition. RoMan's job today is roadway clearing, a multistep task that ARL wants the robot to complete as autonomously as possible. Instead of instructing the robot to grasp specific objects in specific ways and move them to specific places, the operators tell RoMan to "go clear a path." It's then up to the robot to make all the decisions necessary to achieve that objective.
