The present invention is directed to a x-y-axis device and a x-y-z-axis device for micro-manipulating or positioning a crystal for x-ray diffraction. More specifically, the devices which may be placed on the head on a goniometer have small footprints (small in size). The sample may be moved and recorded in step resolutions of 1 micron over an extended range of motion.

A manual quick-release latching system includes a first component and a second component. The first component includes a first component mating surface, a socket recessed into the first component and having an opening on the first component mating surface; and a first component retaining structure. The second component includes a second component mating surface, a second component retaining structure, and a latching mechanism. The mating surfaces are juxtaposed when the first component is slidingly engaged with the second component. The retaining structures slidingly engage one another in a first direction and interlock one another in a direction perpendicular to the first direction. The latching mechanism includes a part that can partially extend from the second component and enter the socket of the first component, to latch the first component with the second component by preventing the first component from sliding with respect to the second component in the first direction.

A manipulator joint includes an encoder having a body and shaft. The encoder body may be fixed to a first housing and the encoder shaft may be fixed to a second housing. The second housing is separate from, distal to, and rotatable with respect to the first housing. Rotation of the second housing may be about a common axis shared with the first housing. A hollow driveshaft, rotatably coupled to the second housing, extends across the joint from the second to the first housing. A torque limiter may be fixedly coupled to the second housing and releasably coupled to the driveshaft. The encoder may be configured to output an absolute angular position of the first housing with respect to the second housing. A method of detecting an over-torque condition of the manipulator joint includes transmitting commands from a processor to the drive motor and receiving data from the encoder.

An articulated manipulator is disclosed, comprising a first arm segment; a second arm segment; an elbow joint disposed intermediate the first arm segment and the second arm segment; and an arm drive sealingly disposed in a drive housing, the arm drive adapted to provide controllable motion of at least one of (i) the first arm segment and the second arm segment. The manipulator may further comprise an azimuth joint rotatably connected to the first arm segment and a dynamic seal disposed intermediate the first arm segment and the azimuth joint. The manipulator may be constructed using lightweight materials and use dynamic seals to afford protection in harsh environments. The manipulator may be constructed to have a total weight of between around twenty pounds to around forty pounds while achieving a reach of around forty inches with a payload capacity of around twenty five pounds. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope of meaning of the claims.
