It is important to inspect pipes used in nuclear power plants and reactors. A number of studies have investigated various locomotion mechanisms of robots controlled by electric cables in pipes. A cableless actuator capable of movement in narrow pipes of less than 15 mm has not yet been developed. The present paper proposes a novel cableless magnetic actuator with a propulsion module that exhibits a high thrusting force. The effect of the magnetic forces generated by two different propulsion modules on the movement of the cableless actuator was investigated theoretically and experimentally. The proposed actuator includes an electrical inverter that directly transforms DC from button batteries into AC. Experimental results indicate that the proposed actuator can move vertically at a speed of 225 mm/s, using the power provided by 10 button batteries when pulling no load mass. This cableless magnetic actuator has several possible applications, including inspection of small pipes.Index Terms-Cableless magnetic actuator, magnetic force, pipe inside mover, propulsion module, vibration.

“…There are several potential problems in the design, however, with regard to extending the range and avoiding tangling of the electrical cable, and thus it is clearly desirable to adopt a cable-free system. However, little research has been conducted on cableless robots (Fukuda et al, 1991;Tsuruta et al, 2002) and electromagnetic vibration type (Yaguchi et al, 2009;Yaguchi et al, 2011;Izumikawa et al, 2012) proposed by authors. Experiment results were compared to analytical results and the validity of the novel motion principle was completely verified (Yaguchi et al, 2013).…”

This paper proposes a cableless In-piping magnetic actuator capable of locomotion over long range of 1,000 m within a pipe having an inner diameter of 10 mm. The cableless magnetic actuator is moved by using resonance energy of a mass-spring system excited by using an electromagnetic force. The proposed actuator incorporates a new type of an electrical inverter that directly transforms DC from button batteries into AC. The electrical DC-AC inverter incorporates a mass-spring system, two reed switches and two curved permanent magnets that switch under an electromagnetic force. The conventional DC-AC inverter and the newly proposed inverter were compared, and the effect of the inverter on the motive properties of the cableless magnetic actuator was examined. The influence of the consumption current of the battery on the range of the actuator was examined. Experimental result demonstrates that the cableless magnetic actuator was able to move horizontally at 1,588 m, and horizontal speed at 176.5 mm/s when two reed switches were used.

“…A number of studies have investigated the mechanisms of an actuator having an attached electric cable to provide locomotion in the pipe using devices such as piezoelectric elements [1,2], shape memory alloys [3,4], and electromagnetic motors [5][6][7][8][9]. However, little research has been conducted on cableless robots [10][11][12]. In general, the design of cable type robots is quite simple compared to the design of cableless robots.…”

The present paper proposes a novel cableless magnetic actuator with a new propulsion module that exhibits a very high thrusting force. This actuator contains an electrical inverter that directly transforms DC from button batteries into AC. The electrical DC-AC inverter incorporates a mass-spring system, a reed switch, and a curved permanent magnet that switches under an electromagnetic force. The actuator is moved by the inertial force of the mass-spring system due to mechanical resonance energy. The experimental results show that the actuator is able to move upward at a speed of 19.7 mm/s when using 10 button batteries when pulling a 20 g load mass. This cableless magnetic actuator has several possible applications, including narrow pipe inspection and maintenance.
