Regarding the two robots handling batteries, they are in fact Fanuc not ABB robots. Fanuc robots are manufactured in Japan and have a UK sales / integration office in Coventry. Fanuc robots are predominantly yellow – their new slogan " Welcome to the Yellow World ". I was Engineering Manager there before starting my own robot installation business.
The full video can be seen at Fanuc USA Web Site – you need to scroll down the page to " LR Mate 200iD and M-1iA/5L Intelligent High Speed Battery Grouping " in the video section ( hope the link works ).
The explanation of the operation of the robots is spot on – the upside down spider looking robot being the M-1iA/5l and the human arm shaped robot being the LR Mate 200iD.
There are some fascinating videos on the website including some of a robot handling a railway wheel set. Robots are always attention grabbers – I've been fascinated by them and working with them for the last 41 years !
