Abstract: A robot sized and shaped for reception in a pipe, the robot including a chassis configured for movement of the robot in the pipe, a plurality of sensors including an inertial measurement unit (IMU), an encoder and a stereo vison camera associated with the robot, and a sensor fusion system operable to combine readings from the IMU, the encoder and the stereo vision camera to determine a position of the robot within the pipe, and wherein the sensor fusion system is operable to use machine learning in creating a digital twin of the pipe.

Abstract: A method includes creating a digital map of an environment, loading the digital map on a moveable robot, wherein the robot is placed in the environment, generating a trajectory path plan from a current position to a desired position using the digital map, the trajectory path having a plurality of waypoints, causing the robot to traverse within the environment in accordance with the trajectory path plan, collecting sensor data in real time while the robot is traversing within the environment, detecting, based on the collecting step, at each waypoint, whether an anomaly is present between an existing waypoint and a subsequent waypoint, and performing a corrective action of the robot based on the detecting step.

Abstract: A method and system for re-establishing fluid communication between a main pipe and a branch conduit extending from the main pipe following lining of the main pipe with a liner includes moving a robot supporting a cutting tool down the lined main pipe to a location proximate to the branch conduit. The cutting tool is selectively extendable from the robot for cutting the liner. The cutting tool is extended from the robot toward the liner at a location where the branch conduit has an opening into the main pipe on an opposite side of the liner. The liner cuts at the location with the cutting tool. The cutting during said step of cutting the liner is monitored and the operation of the cutting is adjusted based on information acquired by monitoring the cutting tool.

Abstract: A robot sized and shaped for reception in a pipe includes a chassis configured for movement of the robot on the pipe, a tool supported by the chassis for movement relative to the chassis, a plurality of sensors including an inertial measurement unit (IMU), an encoder and a light detection and ranging sensor (LIDAR) associated with the robot, and a sensor fusion system operable to combine readings from the IMU, the encoder and LIDAR to determine a position of the robot within the pipe.

Abstract: A method for assessing, by a robot, a feature of an environment based on data from one of the plurality of sensors, wherein the robot is positioned in the environment includes comparing, by the robot, the feature of the environment to an expected feature of the environment; creating, by the robot, a feedback loop based on the comparing step; and adjusting an operational condition of the robot based on the feedback loop.

Abstract: A robot and method of controlling a tool carried by a robot in a main pipe where the tool is operable to extend into a branch conduit extending from the main pipe. The robot can be moved to a location in the main pipe corresponding to a branch conduit opening location where the branch conduit opens into the main pipe by referencing a digital map of the main pipe. The tool can be extended from the robot toward the branch conduit opening at an angle corresponding to an angle the branch conduit makes with the main pipe so as to reduce the likelihood of contact of the tool with a wall of the branch conduit.

Abstract: A method for controlling movement of a robot in an environment, wherein the robot has a plurality of sensors associated therewith.
