Ocean robot plans its own experiments

AUV (MBARI)Scientists in the US are using an underwater vehicle that can “plan its own experiments” on the seafloor.

The “Gulper AUV” is programmed to look for the information that scientists want and plan its own route, avoiding hazardous currents and obstacles.

The research team described this advance at the Ocean Sciences meeting in Portland.

The group explained how it could “train” the robot to bring the best science back to the surface.

Thom Maughan from the Monterey Bay Aquarium Research Institute (MBARI) in California was one of the engineers on the project.

He explained how the autonomous underwater vehicle (AUV) used a piece of software called “T rex”, which operates in a similar way to the software used to control Nasa’s Mars Exploration Rovers – helping them to avoid obstacles on the surface of the Red Planet.

One main difference between the two pieces of software is that for the Mars rovers, the software ran in the control centre on Earth. With this marine vehicle, it runs onboard the robotic vehicle.

“You can tell it what to do before you put it in the water,” Dr Maughan said.

“We tell it, ‘here’s the range of tasks that we want you to perform’, and it goes off and assesses what is happening in the ocean, making decisions about how much of the range it will cover to get back the data we want.” …
