Systems and methods for robotic inspection of above-ground pipelines are disclosed. Embodiments may include a robotic crawler having a plurality of motors that are individually controllable for improved positioning on the pipeline to facilitate image acquisition. Embodiments may also include mounting systems to house and carry imaging equipment configured to capture image data simultaneously from a plurality of angles. Such mounting systems may be adjustable to account for different sizes of pipes (e.g., 2-40+ inches), and may be configured to account for traversing various pipe support structures. Still further, mounting systems may include quick-release members to allow for removal and re-mounting of imaging equipment when traversing support structures. In other aspects, embodiments may be directed toward control systems for the robotic crawler which assist in the navigation and image capture capabilities of the crawler.

A work machine may include an idler wheel, a drivable track engaged with the idler wheel, and an actuator configured to move the idler wheel to adjust the tension in the drivable track. A controller may actively instruct the actuator to adjust the tension in the drivable track based on the pressure in the actuator and variables associated with the drivable track and the work machine.

A work machine may include an electric motor, an idler wheel, a drivable track engaged with the idler wheel, and an actuator that is electrically powered by the electric motor and configured to move the idler wheel to adjust the tension in the drivable track based on the torque output of the electric motor. The work machine also includes a controller configured to automatically control the electrical current input to the electric motor based on one or more monitored control factors associated with the work machine.
