WiFi - how can I talk to my bot with it?
March 28, 2009
I don't know much about networks and communications but most laptops and routers these days are wireless. Can we use this to interface with our bots?
A quick google on WiFi protocol told me that it is technically referred to as the 802.11 protocol.
The Xbee transceivers can also form a wireless network using the 802.15.4 protocol.
Is there some way of connecting a robot via WiFi using an Xbee? Rik has a blog on the subject. Unfortunately the router is too big for what I want and I still didn't understand how to use it.
As all of you have been offering ideas and showing me products I did not find in my initial search I wonder if the answer hasn't been staring me in the face the whole time.
This is the WiFi / USB adapter I bought for my PC when I got the wireless router.
It is small, low powered and relatively cheap. I suspect that once the network settings have been entered from the computer it would only need dirvers for communication.
Unfortunatly I have no idea how to implement this idea. Even if I can plug it into the PC to enter the network settings and then plugged it into a robot with say an Arduino or Picaxe brain. How would I then communicate with it?
And the winner is!
Thanks for all your input. It is apparent to me that if I really want to use the 802.11 protocol that my computer and laptop use then the module found at Sparkfun by Robologist is probably best value for money. It is also very small and should interface well to any microprocessor.
For now, the Xbee Pro is nearly half the price and has much better range. I can still communicate with my robots from the PC or laptop using a USB adaptor available for the Xbee modules.
