A legged mobile robot, a legged mobile robot controller and a legged mobile robot control method are provided to perform a loading operation to load a gripped object in parallel on a target place having a height where a stretchable range of arm portions of the legged mobile robot is enhanced with no operator’s handling. The label holder includes a rearwardly extending leg adapted to be captured by the lower lip of the C-channel, a portion of which is resilient and arcuate, extending first upwardly and then downwardly to provide a spring-like element, the effective length of which can vary depending on the spacing between the lips of the C-channel. An example carrier in the system may include a first part and a second part. A corrosive agent is applied to the portions of the solid surface material exposed by the design of the mask to engrave the surface of the solid surface material. Also provided are layered articles comprising a first layer having the described fluoropolymer blend and methods for making the layered articles. The coil has first and second coil parts 15 and 16 arranged circumferentially in front and back of the permanent magnet 13, and a frequency of an alternate current applied to the first and second coil parts 15 and 16 is made to accord with a resonance frequency of the capsule device 10 generated by a back and forth vibration of the permanent magnet 13.
