Web controlled Wireless Robot
This robotic platform can be driven from the web. It uses an ioBridge IO-204 to link things together.
“The robot uses a pair of serial bluetooth adapters to form a wireless link with the ioBridge IO-204. The serial levels of the IO-204 are TTL and a circuit using the MAX-232 was required to allow the serial interface work properly. On the robot is a set of serial servo drivers that control the steering and speed.”
