Controllers for inspection robots traversing an obstacle are described. In an embodiment a controller may include an obstacle sensory data circuit to interpret obstacle sensory data provided by an obstacle sensor of an inspection robot, an obstacle processing circuit to determine refined obstacle data, and an obstacle notification circuit to generate and provide obstacle notification data to a user interface device. The controller may further include a user interface circuit to interpret a user request value from the user interface device, and to determine an obstacle response command value in response to the user request value; and an obstacle configuration circuit to provide the obstacle response command value to the inspection robot during the interrogating of the inspection surface.
