Gesture-controlled robot arm enables civilization's most meta high five

This video, criminally, doesn't actually show any high fives, but we're sure the students at the University of Tsukuba have sustained endless LOLs over the past few months, pushing their gesture-driven robot arm system to the limits of human-robot high five interaction. The system itself is relatively simple: it uses two cameras to track a hand's movements, including specific finger gestures, which are then processed and translated into robotic movement in real time. The end result is basically the world's most elaborate claw machine game, as demonstrated above.
