Not so long ago it was very difficult to build a hobby robot capable of interesting behavior, because you had to design and build almost everything yourself. Today, robotics can be a fantastic hobby for almost everyone because the technology has advanced to the point where most of the complex things you need can be bought at reasonable prices. Unfortunately, even if you've purchased the necessary sensors and motor controllers, you still need to pair them with a microcontroller and write sophisticated drivers to handle all the messages, time and interrupts before you can even start building robot apps. At least that's what they've done so far. The RobotBASIC Robot Operating System (RROS) provides the hardware interface and all the low-level software required for various sensors and motors in a single 24-pin chip.
