In Pictures: 15 amazing tech feats and world records

Not to be outdone by athletes at this summer’s Olympic games, techies have been setting some world records of their own of late.

Rubik’s master

English computer scientists used LEGO building blocks to construct CubeStormer II, a four-armed robot that set a world record for solving a Rubik’s cube in 5.27 seconds, demolishing the previous robotic world record of more than one minute. The robot uses a Samsung Galaxy S II smartphone, which analyzes the cube and transmits the moves needed to solve the cube to the robot. Humans aren’t far behind at 5.66 seconds.
