A prototype micro-autonomous positioning system for mirror deployment within multi-object instruments

Abstract

The complexity and size of instruments for next generation telescopes demands innovative approaches to existing problems. Within this framework, we present MAPS; a Micro Autonomous Positioning System for mirror deployment in an E-ELT instrument such as EAGLE. The micro-robots have a 25mmx25mm footprint and utilise RF communications and small rechargeable batteries to be completely wireless. Coarse positioning and fine alignment is achieved through the use of miniature gear motors and gearheads. Positional information is determined externally and corrective motions relayed to the robots. This paper reports on the challenges which such a system presents, current developments, and areas of expected future research.
