Swimming snake robots

A bio-inspired solution for subsea inspection and intervention

Swimming snake robots are motivated by the long, slender and flexible body of biological snakes, which allows them to move in virtually any environment on land and in water. The swimming snake robot is a highly flexible and dexterous manipulator arm that can move underwater by itself. This highly flexible snake-like mechanism have excellent accessibility properties; it can for instance access virtually any location on a subsea oil and gas installation, move into the confined areas of ship wrecks, or be used for observation of biological systems. Furthermore, not only can the swimming manipulator access narrow openings and confined areas, but it can also carry out highly complex manipulation tasks at this location since manipulation is an inherent capability of the system. By incorporating the propulsion system and the manipulation capabilities in the same mechanical structure, this vehicle becomes highly compact and is able to bring inspection and intervention capabilities to locations where ROVs today cannot operate. In the longer term, this may enable reduced size and cost of subsea production systems.

In this talk, I will present swimming snake robots as a new solution for subsea inspection and intervention, and I will present recent research results on swimming manipulators, including both theoretical and experimental results.
