'The step from micro-technology to nano-technology requires more than a reduction of size by a factor of a thousand. If you want to move precisely in the nano-world, you don’t succeed by perfecting proven techniques.' Handelsblatt. This quotation shows a new approach to Nanotechnology that is somehow unusual. Exactly this new approach is realised in a new system of Nanorobotics. It allows the development of a production system that is by orders more precise than classical production lines. Moreover, it includes the adhesive bonding technology which oftentimes is the preferred joining technology on this scale. The described system is the result of an industrial demand to solve the actual problems of micro production technology.
The aim for a spectrograph feed from the Subaru prime focus is to have 400 fibers. Since the are of the field is only approximately 1/10 that of the 400 fiber two degree field system on the Anglo-Australian Telescope, placement of magnetic buttons by a robot, as done for 2df, was not considered applicable. Instead, a concept has been developed in which each fiber is held on a spine which can be tilted to position its tip anywhere within a circle. With targets randomly scattered over the field and the radial range for each spine equal to the spine pitch, the success rate in reaching targets is acceptably high. At the f/2 focus, a spine tilt of 1/20 radian is just acceptable and requires the spines be 140 mm long. Two basic mechanisms for tilting and holding such a spine have been investigated experimentally. The first uses three commercial miniature linear actuators set parallel and linked to the base of the spine through simple flexures. A prototype has been built and demonstrated to perform satisfactorily. Another approach is to mount the spine ona ball joint and drive it directly in tip and tilt using a bending piezo impact drive. A prototype of this from has been built; initial test are promising.
