A recently granted patent (Publication Number: US11964388B2) discloses a robot system that includes a continuum arm robot with at least one ferromagnetic section and an external controllable electromagnetic device. The ferromagnetic section on the robot can be attached to the external device through magnetic attraction. The system allows for precise positioning of the robot within a workspace by activating the electromagnetic device, which can be controlled by an operator or another robotic device. Additionally, the system can be retrofitted onto existing continuum arm robots, enhancing their functionality.

The method outlined in the patent involves inserting the continuum arm robot into a workspace, positioning it as needed, and activating the external electromagnetic device to lock the robot in place against the workspace wall. This allows for the robot to perform tasks effectively within the workspace before being released by deactivating the electromagnetic device. The method can also involve using multiple electromagnetic devices to pull the robot through the workspace to a desired location. Overall, the patented robot system and method provide a versatile and efficient way to manipulate and control continuum arm robots in various work environments, offering potential benefits in tasks requiring precise positioning and manipulation capabilities.
