Two mobile teleoperated systems developed for accident recovery activities at Three Mile Island Unit 2 offer essential perspectives for future remote system developments. The remote reconnaissance vehicle (RR V) set precedence for remote operations logistics, tested system philosophies, and clarified recovery objectives. The remote work vehicle (RWV), a subsequent development for cleanup activities, overcame limitations of its predecessors, evolved and integrated design philosophies adopted from related disciplines, and achieved functionality for decontamination and demolition tasks. The features and capabilities of the RR V and RWV as well as issues that influenced their development are discussed.
