As iRobot and University of Washington Team Up, Robotic-Sub Competition Heats Up
This week, iRobot made a splash with the news that it has signed a sole licensing agreement with the University of Washington in Seattle to commercialize UW’s “Seaglider” underwater robot. The specific terms of the deal with UW TechTransfer were not disclosed, but the announcement marks the Bedford, MA-based robotics company’s first foray into the autonomous underwater vehicle (AUV) market.
Best known for its Roomba vacuum cleaners and military PackBots, iRobot is diving into a field that includes local competitors like Cambridge, MA-based Bluefin Robotics and Hydroid in Pocasset, MA. The company sees oceanographers and military planners as the main potential buyers of the technology—anyone who wants to monitor the properties of the ocean environment accurately and over long periods of time.
“We’ve been looking at entering the underwater space for a while,” says Helen Greiner, cofounder and chairman of iRobot (NASDAQ: IRBT). She says her team was impressed by the Seaglider technology, and earlier this spring, after talking with UW, she sent MIT roboticist and iRobot CTO Rodney Brooks (an Xconomist) out to Seattle. “He bridged the gap between the academic community and the company, and was a really good ambassador,” Greiner says. “Universities exist for scientific reasons, for doing research, while at the same time they want to get their baby out into the world.”
What impressed Greiner most about the Seaglider was its efficiency and durability. Developed by researchers at the UW Applied Physics Lab and School of Oceanography, each Seaglider is about the size of a person (1.8 meters long, 52 kilograms) and is shaped like a torpedo with wings that allow it to “glide” through the water. It can travel distances of several thousand kilometers—going out to sea for six or seven months at a time—diving to depths of up to 1 kilometer and surfacing periodically to get a GPS fix or transmit data. (You can even track in real-time where the 70-odd Seagliders are deployed in the field, including one off the coast of Washington, here.)
It does all this with no moving external parts, which is key—most AUVs out there use propellers, which allow them to move much faster than the Seaglider’s 25 centimeters per second, but they don’t last very long in the field (just a few days, for instance). With Seaglider, “you don’t need a ship in the area to pick them up and drop them off,” says Fritz Stahr, head of the Seaglider Fabrication Center at UW, which builds the vehicles for research groups. “You deploy them and go away.”
The iRobot deal should benefit the University of Washington’s development teams in terms of reach and exposure. “We can’t build very many at the same time, so we’ve usually had a year-long backlog,” says Stahr. “So it’s always been in the university’s plan to do a license. This will allow the vehicle to see uses far beyond academia, to make it to markets heretofore unseen.”
