Xbox remote and IR receiver?
I am making a robot (maybe a battlebot)(not for competition) and I was thinking perhaps I could connect an xbox remote to it.

There are 2 ways I am making 2 robots, 1 will use an IR receiver with an Arduino and the other will use just an average receiver/transmitter.

How can you control the speed of the 2 robot options(it needs to be done wirelessly A few solutions could help.

Is it also possible if I manage to connect an xbox remote to 1 of the robots I could use some of the buttons (e.g.a, b, x, y, rt etc)

Also, ow to control the speed of a dc motor in the robots mentioned above. I have looked at h-bridge and am unsure on how to connect the parts and whether it will work.
If there is any other way please help or help on H-bridge
Please help.
