I want to make many 1 DOF robots (Maybe 7, 8 or more). They should be as light as possible! So I can't use many parts for each of them. Just a battery, a servo, a wheel and some kind of reciever.
I do not know what sort of remote controll is best for them. Maybe WiFi is good but I guess the robots will get heavy. I can not use the multichannels Transmitter/Receiver because they have just one receiver which can not be pluged into many bots away from each other. I need a receiver for each.
