Re: Robot to robot communication
 

well yea, I wouldn't go out and buy a FCC license to use a certain frequency, I dont know why someone was even thinking of that

I don't mean that in a mean way, I just don't why you would even need something like that for a hobby project, if you know then please share. Unless it is an air based frequency I know bout all that.

Re: Robot to robot communication
 

Actually, you wouldn't buy a frequency liscense, you would use an open frequency (like 900 MHz) and then need to get FCC part 15 approval by a registered lab. It isn't actually that hard, it just costs a fair amount.

Re: Robot to robot communication
 

There are various FRS frequency bands that don't require licensing as long as the power remains below a specified minimum level. Walkie Talkies are avaiable from various manufacturers for the 27, 49, 900 MHz bands, etc. Various services use these bands, i.e. modeling, experimentation etc. If you are using a n FCC type approved device to begin with you don't need to go through all the goverment paper work as long as it is in band, doesn't interfere with other services and stays below the max. power levels. For devices in an enclosed space in close proximity to each other, you should have no trouble finding transceivers to fit you needs.

does anyone have ideas about the actual problem I posted. It isn't a project i am working on, just something i would like to work on with a few friends

Re: Robot to robot communication
 

With the robots you could get a coded walkie talkie(the ones that have a chanel then a code on it) and rig them so that whenever a robot needs to send a signal to another it can send a series of beeps to that robot on its frequency code, you can then have a base station which uses the uncoded chanel and can "read" all input sent by all the other robots
