Rybot is a heavyweight robot from Swindon, Wiltshire, that attempted to enter Series 8 of Robot Wars. It ultimately did not appear in the series, as its owner Krissy Knee could not get it ready in time for it to compete. In response, John Findlay of Team Roaming Robots allowed Knee to enter his new robot Halo into Series 8 in Rybot's place, but it too was not selected to compete. On 16th May 2016, it was revealed by his son George on Facebook that Krissy had died aged 56 after having cancer for the past seven years, in his lung, his kidney, his heart and his brain.
