Never work with children or (robot) animals! Watch the moment Boston Dynamics' robot dog falls down a flight of stairs and breaks at Jaguar Land Rover's battery testing facility in Coventry

This is the moment a 60,000 robot dog takes a catastrophic fall down a flight of stairs and breaks during a botched demo. MailOnline caught the dramatic event on camera during a visit to Lyons Park, Jaguar Land Rover's battery testing facility in Coventry. Small parts scatter the floor and sparks fly as the industrial helper robot – sold by US firm Boston Dynamics – struggles to get back up. Gonzalo Ejarque-Rinaldini, technical project manager at JLR, told MailOnline that the poor pooch would need replacement parts installed before it could walk again. 'My trust in Boston Dynamics is as high as always – these machines are top class,' he told MailOnline.
