Abstract
A device for transporting a sensor assembly down a bore of a known diameter comprises a pair of wheels offset in a radial direction by a first radial distance from a longitudinal axis of the sensor assembly and at least one eccentric weight. The first radial distance and a lateral distance between the wheels and a diameter of the wheels configures the device so that, in use, a longitudinal axis of the sensor assembly is substantially coincident with a longitudinal axis of the bore when the wheels are in contact with a wall of the bore. The at least one eccentric weight is positioned so that a centre of mass of the combined device and sensor assembly is offset in the radial direction from the longitudinal axis of the sensor assembly by a second radial distance that is greater than the first radial distance to orient the device and sensor assembly by gravity in a most stable position with the rotational axis of the wheels and the centre of mass below the longitudinal axis of the sensor assembly with the wheels in contact with a low side of the wall of the bore.
