Radio Transmiters

FIRST General Forum
#1

Does anyone know were I could maybe find a Radio Transmitter for our teams Edu Bot? I’m my teams new programmer, and I could use some practice programming an Edu Bot with a controller. So far I have a basic little program set up with it. It just goes around in a square. Anyway, If anyone could maybe give me a good website URL that has some transmitters that are relatively cheap that I could order for my team, that would be cool.

~Thanks!

You can get it from IFI. Good luck.

This Futaba Ground radio is a little bit cheaper and as a bonus you get a couple or servos. http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXBCP2**&P=0

I cant seem to find any hobby raidio transmitters on here for an EduBot. Could you maybe supply an exact URL? Thanks.

#5

Thanks Sanddrag. Would this controller work on a standard EduBot?

If it is the 2004 Mini-RC (programmed in C) as in the IFI link above, then yes it will definitely work. We use that exact radio with ours. There are some more radios here http://robotcombat.com/marketplace_rc.html but the one I lined to earlier at Tower Hobbies is the cheapest I have found. It is 4 channel. You can use two radios, or get one radio with more channels if your project requires more functionality than four channels can provide. You can think of the 4 chanel radio as two dual axis (x and y) joysticks with no buttons.

Ok. Thank you very much. Like I said, this is just a practice robot. Once the rest of my team gets most of it finished, we are going to make a mini Omni Bot. That will prove to be interesting to program as my first real program.

On the serial port for the FIRST transmitter/receivers pin 1 is +5 volt power right?

If you just want to be able to supply some inputs to the robot controller you can use the application available for download here: members.cox.net/seanwitte. The RC must be connected to the PC via a serial cable, but its good for basic testing. The UI has four “virtual” joysticks and 8 switch inputs and received 8 bytes, 16 bits, and 6 ints of feedback from the RC. You can also capture and plot up to ten of the channels.
