Video Friday: Robot Roller Skating, BonsAI Tree, and Thor's Hammer

Video Friday is your weekly selection of awesome robotics videos, collected by your Automaton bloggers. We'll also be posting a weekly calendar of upcoming robotics events for the next few months; here's what we have so far (send us your events!): Let us know if you have suggestions for next week, and enjoy today's videos. It's nearly as fun to watch when it's working like it's supposed to, on flat surfaces: Not only can BonsAI seek out sunlight when it needs it, it can also tell you when it's thirsty, and provide sage advice when asked. According to the website, "BonsAI is a bit smarter than a man, because it lives longer than a human being."
