Must have been a real stinker ;@}.
Obviously only conventional R/C stuff is power limited in the way you describe. The op stated Ham radio gear,from which I assume SW, and not subject to the same limitations power wise. However first problems he needs to solve are probably getting a high enough data rate to know what the robot is doing. Video is doable, but pretty hard over SW, I don't know what bandwidths Hams are allowed. Integrating to any micro is simply a case of converting data into a format that the micro can understand, ie NRZ serial, or pulse length coded. I would start by looking at something like the FX929 from CML. it handles the micro to radio interface, and includes FEC etc, it is designed for short packets. failing that packet radio, which, as a Ham you should probably knwo more about than I do, is designed explicitly for data comms like this. You can then choose to implement your own direct control scheme of the robot, ie PWM motor controol or what have you, or read up on R/C servos. these are pretty simple, IIRC 20ms between pulse, and pulse of from 1-2ms to set the 'position' of the servo. Use the micro to convert complex instructions into servo control signals. Al Active8 wrote: boy, i must have had a bad day. |
