Add to ORKGIn a feasibility study the potentials of learning energy-autonomous mobil robots for waste water channel maintenance have been investigated. From an analysis of the state of the art the feasibility of auonomous channel robots with improved mobility and radius of action is concluded, and the required additional research and development activities are outlined. A robot prototype for selected experiments has been constructed, and a conception for the design of a channel robot platform has been derived.
