Singularity Hub – Singularity Hub is the main place I check for crazy new robots. They also have news about other stuff including artificial intelligence and biotech.
RobotNext – Kind of like Singularity Hub but just robots.
Make Magazine – Make is geared toward inventors and DIY-type people. There’s also a thing called Maker Faire that’s held annually in Austin, Texas.
LEGO Mindstorms – I have the LEGO Mindstorms NXT 2.0 and it’s pretty awesome. I also have this book which goes well with the kit.
Arduino – I haven’t used Arduino myself but it looks like the next step up from Mindstorms.
iRobot Corporation – This is the company that makes Roomba. The other robots they make are pretty cool, too. Their government and industrial robots are especially terrifying.
This article to be updated as I find more robotics resources.
