“…An actuator combined with an electromagnetic force and mechanical vibration was previously proposed by the authors [15][16][17][18][19]. However, robots capable of inspection in a pipe with an inner diameter of 25 mm have not yet been developed except in a small study [20]. It should be possible to create a micro-motor which generates torque and then transforms it into movement through the complex pipe in the same way as standard actuators, but the torque produced by micro-motors is quite small.…”

This paper proposes a magnetic actuator using multiple vibration components to perform locomotion in a complex pipe with a 25 mm inner diameter. Due to the desire to increase the turning moment in a T-junction pipe, two vibration components were attached off-center to an acrylic plate with an eccentricity of 2 mm. The experimental results show that the magnetic actuator was able to move at 40.6 mm/s while pulling a load mass of 20 g in a pipe with an inner diameter of 25 mm. In addition, this magnetic actuator was able to move stably in U-junction and T-junction pipes. If a micro-camera is implemented in the future, the inspection of small complex pipes can be enabled. The possibility of inspection in pipes with a 25 mm inner diameter was shown by equipping the pipe with a micro-camera.

This paper proposes a simple reduced-order model for a general flexure-guided piezoelectrically actuated nanopositioner and employs it to derive the upper limit of achievable bandwidth for a specified travel range. It is shown that flexure-based motion amplification enables achieving higher bandwidth than that obtained when they are used for guiding motion alone. The optimal amplification and the corresponding maximum bandwidth are studied as functions of the mass carried by the positioner and the stiffness of the flexure. Simple analytical expressions are derived for the two in case of stiff flexures carrying small mass. The proposed reduced-order model is validated by means of finite element analysis.
