"But then you have people moving, and the robot gets completely lost because it's using static features in the environment." "A lot of times what will happen is that you can have a robot, and it'll map a building beautifully," he says. All that is usually calculated with the assumption that things won't move, Singh says. But mapping an object in constant motion is a robot's Achilles heel.Įngineers who work on autonomous drones often come up against this challenge, since robots need to scan and map their environments to move effectively and autonomously. To get a concrete idea of the rate of melting, accurate measurements of the shape and surface of an iceberg need to be compared over time. "The icebergs move, and they're moving fast, some 10 kilometers a day."
"That's very poorly understood," he says.

Singh, a professor of electrical and computer engineering at Northeastern, says the problem is figuring out how to measure large pieces of ice that are in constant motion. Scientists know icebergs breaking from the Greenland ice sheet are melting fast in response to climate change, but the specifics of how quickly they are melting are still unclear. Or at least that's what Hanumant Singh factored into the robot's algorithms in order to render sharp 3-D maps of icebergs in Sermilik Fjord, a 50-mile inlet into the shoreline of Eastern Greenland.
