We first came across Ziphius when Rob Bishop went to do some talks and workshops in Portugal. Ziphius is a Pi-powered aquatic drone, equipped with cameras, who displays autonomous behaviour and can also be controlled from your phone or tablet. I say “who” rather than “which” because despite the lack of a face, arms or legs, Ziphius has a very singular character and, once powering through the waves, seems oddly cheerful and friendly
