Hi ppl, I am working on a project that involves building multiple small and cheap mobile robots. These robots are semi-autonomous in the sense that they take instructions from the main computer, while also doing some local processing. I need to get instructions across to the mobile units from the main computer.
I plan to use a radio link for this. I cannot use an analog, limited-channel radio link, instead I think digital will be better suited to this project.
I do not want to spend a lot on each robot. So I cannot go in for those fancy radio control sets that are available with toys. Can you guys tell me where I can find a low-cost single chip radio transceiver ic and the circuitry to interface the same with a microcontroller? Has anybody worked on a digital radio controlled robot before? (coz most of the rc robots i've seen use some form of an analog radio link)
thanks a lot in advance ppl, Prashanth Ellina snipped-for-privacy@gmx.net
