Abstract: An assembly and method for detecting cross bores and the location of underground pipe system assets includes an acoustic generator placed within an interior of the sewer system and an acoustic receiver placed within proximity of the lateral(s) of the pipe system. The acoustic generator generates an acoustic signal to transmit through the interior of a sewer pipe of the sewer system. A controller detects, in response to the acoustic receiver hearing the acoustic signal, a location of the underground pipe.

Abstract: A robotic system is configured to autonomously or semi-autonomously rack a circuit breaker from an electrical cabinet or other electrical-connection station. The robotic system may perform work on circuit breakers, ground-and-test devices, or other electrical equipment.

Abstract: A pipe rehabilitation system and/or robot can be used inside a pipe to measure characteristics of branch conduits, install plugs into branch conduits before the pipe is lined with a liner, remove portions of plugs and liners after lining to restore fluid communication between the pipe and branch conduits, and/or install fittings into the branch conduits to connect the liner to the branch conduits. A probe can measure characteristics of a branch conduit. A tool can install plugs and/or fittings into the branch conduits. A linkage can connect a tool to a robotic tractor so that the connected elements can navigate through a main pipe. A visualization system can aid in aligning a robot with a branch conduit. Height-adjustable braces can support robotic tools in a pipe. A plug can include integrated locating features and/or movable parts that enable expanding the plug to seal with the branch conduit.
