I plan on building a small robot as a hobby. There will be a desktop computer to direct it and at least one microprocessor on the robot itself to perform a number of tasks - certainly movement, the proximity sensing , etc. Its not clear how many sensors will be managed on board the robot and how much will be sent back to the desktop for processing. Video will be sent via a wireless webcam.
To start, I want to make sure that there is a simple and reliable solution to the wireless communications between the robot and the desktop, and in the future between robots. What is available - any suggestions?
