We’ve seen Android hacked together to accomplish some pretty wacky and zany things, and often times those “things” involve an Android handset being the “brain” of an actual robot. I’m not sure anybody does it better than cellbots, who just added voice commands to their bot. Your signficant other won’t listen? Boss around a bot – they always behave!
New additions to the Arduino Truckbo t include compass direction shifting and responding to voice commands: fetch me a rack of ribs in Northern Baltimore! Somehow I don’t see that happening.
Want to build your own? Cellbot even has a little site helping folks like you out on Google Code. Ready, Set, BUILD ME A PESONALY ASSISTANT/TRAINING ROBOT.
