The robot moved through pipes, open valves, and inside various types of vessels.
From the press release:
"Our robot can go places people can’t, particularly in areas of power plants that are radioactively contaminated,”
“It can go up and around multiple bends, something you can’t do with a conventional borescope, a flexible tube that can only be pushed through a pipe like a wet noodle"
The robot is 37 inches long, made up of 16 modules that have two half-joints each, giving the robot a total of 16 degrees of freedom.
It can emulate the gaits of a natural snakes but can also configure itself in unique ways not possible for a biological snake.
