WEAVE是位于西班牙加那利群岛拉帕尔马的威廉·赫歇尔望远镜（WHT）的下一代宽视场光谱学设备。它是一个多目标“拾取和放置”纤维馈送光谱仪，有超过1000根纤维，在概念上类似于澳大利亚天文台的2dF1仪器，有两个观测板，其中一个观测天空，而另一个由机器人纤维定位器重新配置。它将能够在一个晚上获取超过10000颗恒星或星系的光谱。WEAVE定位器概念使用两个机器人串联工作，以便在仪器预期的1小时停留时间内重新配置一个完全填充的区域（由于差折射的影响，所需曝光时间与给定配置的有效性限制之间的良好匹配）。这给确定从一种配置到下一种配置的最佳路径的软件带来了额外的限制和复杂性，特别是考虑到1000根光纤多路复用所隐含的大量光纤交叉。本文描述了现场组态工具的原型实现中使用的算法和编程技术，以及为支持WEAVE的详细设计而开发的纤维定位机器人控制器。
WEAVE is the next-generation wide-field optical spectroscopy facility for the William Herschel Telescope (WHT) in La Palma, Canary Islands, Spain. It is a multi-object "pick and place" fibre fed spectrograph with more than one thousand fibres, similar in concept to the Australian Astronomical Observatory's 2dF1 instrument with two observing plates, one of which is observing the sky while other is being reconfigured by a robotic fibre positioner. It will be capable of acquiring more than 10000 star or galaxy spectra a night. The WEAVE positioner concept uses two robots working in tandem in order to reconfigure a fully populated field within the expected 1 hour dwell-time for the instrument (a good match between the required exposure times and the limit of validity for a given configuration due to the effects of differential refraction). This presents additional constraints and complications for the software that determines the optimal path from one configuration to the next, particularly given the large number of fibre crossings implied by the 1000 fibre multiplex. This paper describes the algorithms and programming techniques used in the prototype implementations of the field configuration tool and the fibre positioner robot controller developed to support the detailed design of WEAVE.
