Father Christmas looks to be giving Rudolph and his reindeer pals a night off this year after upgrading his sleigh.
American engineering firm Boston Dynamics has created a group of robot reindeer that are capable of dragging Santa's sled, as revealed in its Christmas message.
The firm, which develops technology for the US military, posted the festive video on YouTube, featuring a female member of staff dressed as Mrs Claus driving the automated animals.
