Provided are a deformable tracked pipeline robot, and a differential turning method thereof. The deformable tracked pipeline robot includes a robot main body. Three tracked foot modules in a circular array are arranged on an outer side surface of the robot main body, each tracked foot module is connected to the robot main body through a center variable-diameter module. A spacing between the tracked foot module and the robot main body can be adjusted through the center variable-diameter module, making all three tracked foot modules in contact with an inner wall of a pipeline. According to a differential turning method based on space curve measurement, the pipeline robot can pass through pipelines with various curvature radii. A pipeline axis is measured by a Charge Coupled Device camera module as a bending curvature of a space curve. The accuracy of space curve fitting is improved by a recursive algorithm.
