A modular radio includes a chassis holding a network infosec unit module; a power amplifier module; and at least one transceiver module. A plurality of flanges or wings are spaced apart longitudinally at an opposite and free end of the body and define flat laterally extending anchoring surfaces. The moving amount that can be set by the operation of the manipulator lever has a relatively small moving amount that the robot may be moved by performing a liftinglanding action once for each of the legs of the robot, and a relatively large moving amount requiring multiple walking steps of the liftinglanding action for each leg of the robot. The authentication apparatus also acquires biological information from a part of the living body selected by a user, and then generates personal authentication information based on the biological information acquired. The distal end of each pin includes an engaging clip enabling the distal ends of each pin to fixedly engage and secure the roll within the dispenser.
