Mark Zuckerberg is planning to build himself a robot servant in 2016.
The Facebook founder said in a status update that he had set himself the goal as a challenge for the new year.
His plan is to build a "simple" artificial intelligence (AI) which would help run his house and his work – "kind of like Jarvis out of Iron Man".
In the films, J.A.R.V.I.S. is an intelligent computer with a posh British voice which controls Tony Stark's house and equipment.
A lot of the technology Zuckerberg needs to make his robot butler already exists. For instance, voice recognition software is already widely available.
He said: "I'll start teaching it to understand my voice to control everything in our home – music, lights, temperature and so on."
