Hi
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.
It comes to mind that each robot can have a RF reciever and there is a RF transmitter. Each reciever has its own frequency to control. The frequency on the transmitter should be adjustacle for each robot. I am not sure about the weight of the robots in this structure. and does such RF transmitter exist?
And even IR Transmitter/Receiver is posible but again I am worry about the weight. what other elements should I use if i use IR?
It will be very good if i could control robots simultaneously.
Any comment or recommendation is appreciated, ;-)
Thanks
You haven’t mentioned anything about range.
Based on you consideration of IR, I am guessing you are not talking about great distances. That said, what is wrong with using IR? The mass of an IR receiver is negligible. After that you just need enough storage space for the code to be able to decode whatever is sent. Multiple robots just require that your code supports multiple addresses. Admittedly, your transmitter might actually require brains as well, instead of just using an off the shelf remote control. It really depends on how you write your code, I suppose.

they are going to move in a room about 5*4 meter!
Where can I find more information on IR? I did not understand the mean of addresses.I am beginner in the field.
And can I control multiple bots simultaneously by IR?
IR should work just fine.
IR should work just fine. All you need is a IR receiver sensor (PNA-4601 or TSOP4838) and use the Sony protocol in what ever microcontroller you chose. Just google these terms and you’ll find lots of examples. The remote needs to be strong enough to reach in the whole room, but the walls and ceiling also reflect the light. A universal TV remote programmed for a Sony TV will do the trick. Or, you can have a high power IR LED connected to a microcontroller through a transistor to have it all automated.
I could not find the
I could not find the receivers you suggested in the shops here! but they recommend me to use RYS1838T. There is no English written datasheet for it on the net! I found a chinese one and translated by Google translate, It was mentioned only that the supply voltage is 3 V! But there are some questions.
There are three leads! What are these leads? and Are ther any ristrictions in current flow ot something else?
