ABSTRACT:
Methods and tools for cleaning pipes or pipe networks based on characteristics of pipes and debris in the pipes. A mobile platform includes a cleaning head and a sensor head. The platform implements a cleaning plan and senses characteristics of the pipe and debris. The cleaning plan is incrementally updated based on the sensed characteristics, and can be automatically updated using software. Many different cleaning tasks can be accomplished using the present platforms including agitation of sediment, pulverization of large debris, and movement of debris to facilitate removal.
