This is Norwegian engineer Kåre "Zenta" Halvorsen's MorpHex, a hexapod robot that can transform and roll out in a ball. You may actually recall MorpHex from this post back in 2012, this is just the new and improved version. Or maybe it's the exact f***ing same, I'm not sure. Whatever the case, when reached for comment about the transforming ball, Optimus Prime just laughed and told the little shit to go join the Decepticons.
Keep going for a video of the bot in action.
Thanks to Luke and viscouse, who agree that would be great fun to run around smacking with a shovel while it tries to roll away.
