Would you rather figure it out on your own or let a robot do it for you?

If you’ve ever been frustrated trying to solve the Rubik’s Cube, this might be the solution for you.

A YouTube video posted under the username Human Controller in Japan appears to show a robotic Rubik’s Cube that can solve itself — in less than a minute.

The colourful puzzle was invented in the 1970s by a Hungarian architect as a way to help his students think in three dimensions.

People use an algorithm — or a standard set of moves — to solve it.

According to the official website for the Rubik’s Cube, it took the original inventor more than a month to solve the puzzle the first time he tried it.

Now people can do it in less than 10 seconds.

They hold competitions to see who can do it the fastest.

The World Cube Association held a speed cubing competition in Winnipeg earlier this month.

Thirteen-year-old Owen Boyko said he can solve the puzzle in 12 seconds.

Calgary is hoping to break the record for largest Rubik’s Cube, which is on display at the local science centre, Telus Spark.

It’s 1.68 metres tall and actually works.

Staff at Guinness World Records have yet to confirm the win.
