Inventor says robo-vaccination machine could be used to combat bovine TB

Tony Cholerton created Robovacc to inoculate a timid tiger at London zoo - but says it could administer jabs to badgers

It began with the tiger who wouldn't come to tea. Cinta was so shy that she refused to feed when keepers at London zoo were around, and staff wondered how they would ever administer the young animal's vaccinations without traumatising her.

So Tony Cholerton, a zookeeper who had been a motorcycle engineer for many years, invented Robovacc - a machine to quickly administer vital jabs without the presence of people.
