Patent attributes
Systems and methods for a robotic system capable of carrying out operations in a hazardous or confined space. The system comprises a manipulator arm, a plinth, a trolley, an end effector, and a control system. The plinth and trolley each comprise one or more locking pawls for securing the system to mounting levels along a length of the manipulator arm. The system is capable of maneuvering between mounting points in an inch-worm-like fashion. Motion starts from a fixed position where both the trolley and plinth locking pawls are secured to a first mounting level along the length of the manipulator arm. The trolley locking pawls are then released and the trolley runs along the manipulator and secures locking pawls to a second mounting level along the length of the manipulator arm. The plinth locking pawls are then released and the plinth is drawn to the second mounting level along the length of the manipulator arm where it is secured via locking pawls. When both the plinth and trolley are secured, operations can be carried out.
