Continuum Robot with Self-Sensing and Coiling Capability for In-bore Robotics Delivery
The RAIN-Snake is a flexible delivery system for in-situ inspection and repair, composed of a flexible delivery arm and an actuation pack (analogous to a small drum). The RAIN-Snake can navigate into hard to reach, hazardous environments for inspection and in-situ repair, and can be used in gloveboxes, and other complex areas. A range of tooling options makes the RAIN-Snake adaptable and suitable for a range of applications. Some examples of tools that have been integrated into the system include:
Soft Gripper: A soft gripper (vacuum) developed by Rolls-Royce was integrated with the snake robot. The RAIN-Snake can be controlled using an on-board camera to navigate narrow spaces. The RAIN-Snake arm carrying the gripper in this instance was used to catch a workpiece.
Raman Spectroscopy: A sensor was attached to the end-effector of snake arm to analyse unknown materials inside a narrow space, using Raman spectroscopy.
