For us? About a week.

For this ungainly robot? Between one and 1.2 seconds.
The creation of software engineers Jay Flatland and Paul Rose, this robot scans a cube with web cams before working out the exact moves it needs to perform in order to complete it.
There's one important caveat: the robot can only solve cubes that have had special holes drilled into it to provide grip.
We wonder if they could make one to solve this monster...
