Smart robots to advance science, perform rescue missions

The team has also built a prototype underwater submersible (called Proteus, after one of Poseidon’s sons known for adaptability) with which to test its novel control systems in aquatic environments.

The UConn research has captured the attention of the National Science Foundation’s National Robotics Initiative (NRI). In September 2012 the NRI awarded Cao’s research team a 4-year, $1.2 million grant to develop a cooperative underwater robotic network that could be used to enhance underwater discovery and rescue. Cao is the principal investigator on the project. Kazem Kazerounian, dean of the School of Engineering, whose background is in robotics and design optimization; and Jun-Hong (June) Cui, an associate professor of computer science and specialist in underwater communication networks, are co-principal investigators.

“The primary purpose of this … initiative is to provide U.S. leadership in science and engineering research and education aimed at the development of the next generation of robotics,” Farnam Jahanian, the NSF’s assistant director for the Computer and Information Science and Engineering Directorate, said last year when the agency announced the NRI initiative to promote novel robotic systems. NASA has been pursuing advanced robotic technologies for more than a decade.

UConn’s project is a prime example of the kind of collaborative research initiatives that the NRI is interested in funding. Cao’s research team is a diverse group, with representatives from the electrical engineering, computer science, and mechanical engineering departments all pitching in.

“We want to have robust and adaptive vehicles that can handle all types of situations and uncertainties,” says Cao. “Our ultimate goal is to have a vehicle like a helicopter that will work in very complex environments such as urban areas with multiple large buildings, or a submersible that can traverse a complex ocean floor. That is currently a challenge to an autonomous system.”

UConn’s Igor Parsadanov, a trained remote control pilot, is assisting the research team with design and trial applications. He sees great advantages in creating autonomous vehicles that can perform dangerous tasks like deep sea rescue, wilderness firefighting, and underwater exploration without the need for human life support systems or the risk of casualties.

“These vehicles use global positioning systems, cameras, advanced sensors, and light detecting and ranging (LIDAR) technology to navigate through their environment,” Parsadanov says. “In this way, the system allows the vehicle to adjust its course by itself. I don’t think it will be too much longer before people are going to start trusting a vehicle they see operating without a person controlling it.”
