Our pal Rollin' Justin proved the old adage about teaching old robots new robo tricks wrong back in April, when he learned to catch balls by tracking moving objects, calculating their flight paths and then snapping shut his cold metal claws at the moment of impact. Now he's besting himself, thanks to a handful of improvements imparted upon him by way of his fleshy masters at the German Aerospace Agency. Among the upgrades are are an improvement to old Justin's dynamic performance -- he's now 1.5 times faster in his arms, thanks to new gear ratios, helping to make his game of robo catch two-sided, with the ability to actually throw. He's also adopted the more flattering moniker Agile Justin and likes to play catch with his older, similarly named sibling. Video evidence of his new-found skills after the jump.
