A method of manipulating a brush relative to a brush-arm assembly of an end-effector comprises locating a carriage in one of a first position or a second position relative to a stationary component. The method also comprises, with the carriage in one of the first position or the second position, different from the first position, relative to the stationary component, locating the brush-arm assembly of the end-effector with respect to the stationary component so that the brush-arm assembly is in contact with the stationary component. The method further comprises moving the carriage in a second direction toward the stationary component, from the first position to a third position, to load the brush onto the brush-arm assembly, or moving the carriage in a first direction away from the stationary component from the second position to the first position to unload the brush from the brush-arm assembly.

A system and method for removing and replacing fire-tubes. The system can include a powered system, a fire-tube puller coupled to said powered system. The fire-tube puller has a puller back which is coupled to a plug rest. A plug rest is approximately perpendicular to the puller back, and the fire-tube will rest upon the plug rest when the fire-tube is being removed or installed. The system can also include a stack adjuster which is coupled to the plug rest. The stack adjuster can couple to a stack so as to reposition the stack.

A robot 140 includes a control unit 160 configured such that a reference line L connecting a root portion of a first arm (upper arm 143) and an end portion of a second arm (forearm 144) is assumed on a main plane determined in a space where the robot 140 is installed, an angle β formed by the first arm (upper arm 143) and the reference line L is decreased while increasing a crossing angle α between the first arm (upper arm 143) and the second arm (forearm 144) on the side facing the reference line L, the end portion of the second arm (forearm 144) is moved in a work pressurizing direction (F direction) which is determined to be along the reference line L, and a work pressurizing unit (push-in unit 153) is pressurized in the work pressurizing direction (F direction) by the end portion of the second arm (forearm 144).

A method of delivering a glutinous substance from a cartridge to an applicator comprises receiving the cartridge inside a sleeve through an inlet of the sleeve when a pressure cap, coupled to the sleeve proximate the inlet, is in an open position. The method additionally comprises moving the pressure cap into a closed position to sealingly couple the pressure cap with a trailing end of the cartridge. The method also comprises selectively causing an automated coupler to automatically sealingly couple the applicator with a leading end of the cartridge when the cartridge is inside the sleeve and the pressure cap is in the closed position. The method further comprises applying pressure to the glutinous substance in the cartridge through a first pressure input of the pressure cap to urge the glutinous substance from the cartridge into the applicator.

Provided is a manufacturing method for a stator coil in which end portions of one-side conductor segments inserted into slots from the side of one end in an axial direction of a stator core and end portions of other-side conductor segments are connected to each other through coupling members inside the slots. The method includes: pressing in the one-side conductor segment or the other-side conductor segment in an insertion direction in a state where the end portion of the one-side conductor segment or the end portion of the other-side conductor segment, or an end portion of the coupling member has been moved toward the inner circumferential side of the stator core; connecting the end portion of the one-side conductor segment and the end portion of the other-side conductor segment to each other; and executing the pressing in and the connecting sequentially from the outer circumferential side of the stator core.
