Snake-arm robots to aid working in dangerous, confined, and cluttered spaces

Snake-arm robots are flexible robotic arms without elbows to get in the way of operating in confined spaces. Snake-arm robots are flexible and compliant, like endoscopes, but they are controllable like a robot and can be precisely positioned, company officials say.

OC Robotics already has developed a snake-arm robot for Airbus in Toulouse, France, for assembly and inspection tasks within aircraft wings -- an area previously inaccessible to automation. The robot for Airbus is capable of sealing, swaging, and inspection inside a mockup of an aircraft wing rib bay. The robot now is set to begin testing.

The snake-arm robot moves its tip around obstacles with a tip-mounted camera. OC Robotics officials say it is effectively a controllable endoscope able to snake into awkward or cluttered environments.
