hey guys, first of all i would like to wish you all a happy new year. i have a couple of questions regarding the feather weight robot i am building. as its a uni final year project, i have to write a source code for the pic im using. im not sure how the remote control communicates with the robot. What frequency the remote gives out for each command? and finally will each basic command i.e left turn, right turn, etc will have separate frequencies? many thanks guys.

Your remote control has a frequency that is determined by the transmitter and receiver crystal. on that frequency a order of signals is being transmitted, called channels.

Typically you have 2 channels for drive. 1 channel for left and right, and 1 channel for forward and reverse. If you use tank style steering it is motor 1 on one channel, and motor 2 on the second.

How many channels you have is determined by the Transmitter. On a third channel you can control your weapon.

This is a good site explaining the RC signal.

Hi all,

Decided to hi-jack an old thread than start a new one.

Ive been interested in robotics for a long while now, and have always intended to build one myself. Now i have the money to build one so I am planning to build myself a simple featherweight. A pic of my design is on my profile.

My design is basically pusher/lifter using drill motors for drive, and with an electric lifter (to avoid pneumatics, spinners etc for my first bot). Im aiming to make a cheap but effective bot.

Ive read through most of the pages on this forum - and most of the links too- but would still be appreciative of any advice people can spare. My contact details are on my profile.

Thanks

Chris
