It’s amazing how far robotics has come throughout the years. From simple robots that could only do menial tasks to advanced robots like the CHARLI-2 that can do the Gangnam style, I guess you can say that roboticists themselves have come a long way.
An example of the latter group of robots is the iRobot. What you see above is just a part of it though. Specifically, that’s the robot’s hand, and it’s about to be ‘smashed’ by a baseball bat. It sounds brutal, but I assure you, it’s not what you think. You’ll understand when you see the clip where the researcher does the actual smashing. You’ll probably come off amazed at how they managed to build such a thing in the first place.
