Segment handling system prototype progress for Thirty Meter Telescope
2016
Segment Handling System (SHS) is the subsystem that is planned to be permanently implemented on Thirty Meter Telescope (TMT) telescope structure that enables fast, efficient, semi-automatic exchange of M1 segments. TMT plans challenging segment exchange (10 segments per 10 hours a day). To achieve these, MELCO develops innovative SHS by accommodating Factory Automation (FA) technology such as force control system and machine vision system into the system. Force control system used for install operation, achieves soft handling by detecting force exerted to mirror segment and automatically compensating the position error between handling segments and primary mirror. Machine vision system used for removal operation, achieves semi-automatic positioning between SHS and mirror segments to be handled. Prototype experience proves soft (extraneous force ~300N) and fast (~3 minutes) segment handling. The SHS will provide upcoming segmented large telescopes for cost-efficient, effortless, and safe segment exchange operation.
