This week's SlashGear Science Week in Review is all robot. We always try to include at least one robot story in each edition, but this week, there were so many robot stories to choose from, we decided to feature all of them. These robots range from robotic arms engaging in an epic lightsaber duel, a cute and cuddly robot toy, a jumping robot (kind of) named after a famous frog, and one robot that seems to be channeling Rosie from the Jetsons. Then, those crazy German engineers who brought us the Rollin' Justin robot are back and this time, they're coming out swinging, as in gleefully whacking a robot with a baseball bat. Also, a couple of robot concepts that we encountered at Google I/O this week. And last, a rolling trash can that isn't a robot, but plays one on TV. Of course, there are lots of videos included as well. Read on for all the robot goodness.
