Abstract:
A method inspects a conveyor (10) having opposing sides (34, 35) and a length. The conveyor includes an endless belt (16) and a plurality of roller structures (24) disposed in spaced relation along at least a portion of the length of the conveyor and under a top flight (17) of the belt for supporting the belt while material is being conveyed on the belt. Each roller structure includes at least one roller (12, 12′) constructed and arranged to rotate about an axis as the belt is conveyed with the material. The method orients an unmanned vehicle (22), having sensor structure (28) thereon, at one side of the conveyor, and causes the vehicle to travel along the portion of the length of the conveyor while the sensor structure obtains data regarding a state of at least a portion of the belt and of rollers of the plurality of roller structures while the conveyor is operating.
Abstract:
There is set forth herein an articulated arm, the articulated arm comprising a first rigid link assembly and a second rigid link assembly. The articulated arm can be configured so that the second rigid link assembly rotates in relation to the first link assembly about a rotary axis. The articulated arm can include an actuator for causing rotary movement of the second rigid link assembly in relation to the first rigid link assembly about the rotary axis. The actuator can include a first fluid chamber, and a second fluid chamber. The articulated arm can include a fluid supply assembly for moving fluid into and out of the first fluid chamber and the second fluid chamber.
