ABSTRACT:
A circular robotic device has retractable extendible surface engaging drives controlled by linear actuators. A pressure transducer indicates the pressure exerted by one such drive on the surface if the pressure is to high the drives are retracted, if the pressure is too low the drives are extended. A more sophisticated version controls the pressure exerted by each drive independently. In a pole centering version this providing a tight clamp allows the device to climb and descend the typically tapered poles. The device can prime and paint poles to predetermined thickness, as well as sandblast the poles. In a pipe cleaning version the drive engage the internal surface of a pipe. The pipe cleaning version carries pipe cleaning and/or X-ray equipment. A microprocessor monitors the device and provides status information to a remote control unit.
