so shiona mccallum has been taking a look at how robotics and 56 could help improve site safety.tjust on any construction site. i am on one in a remote and barren part of the world. shetland. where an internet connection is a luxury. situated at the top of scotland in the middle of the north sea, shetland is exposed to some of the most extreme weather conditions in the uk. there is rain, hail, snow and sometimes there is sunshine. but, crucially, there is also wind. a lot of wind. only one quarter of the renewable wind energy produced on shetland is used to power the island. so here at kergord, the teams are building an electricity converter station and substation. it will connect shetland to the national grid and allow wind farms to export energy south. it is notjust manpower, but new technologies that are making it happen. it is a big project! bosses at bam nuttall thought a private 56 network would be a good idea. faster internet speeds and better connectivity. we've got a fibre—optic connection that runs in the road just down the valley, we have a microwave link that takes th
