Recommendations for WiFi components

Hi guys,

 

I'm thinking of using WiFi as a mode of communication with my robot from my laptop.

 

So far, I'm only able to find three modules by Roving Network on SparkFun:

what are the specs to lookout for in selecting the right module?

General help Needed - Desiging next robot

Hi. I am making a robot that runs like a car but has a camera on it and runs over wifi. Sort of an city explorer bot. Does anyone have any suggestions on the parts I need (based on my framework), or any other parts? Or any other recommendations whatsoever? any help isgreatly apprieciated.

Routerbot (Without hacking the router)

I am intending to build a routerbot. This is my design idea. This is my first major robot so please comment and suggest if even the slightest urge arises.

I will call the robot flat friday.

Design brief so far...

WiFi - how can I talk to my bot with it?

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.

This is the very popular 2.4GHz XBee module from Digi (formally Maxstream). These modules take the 802.15.4 stack (the basis for Zigbee) and wrap it into a simple … Read more

wrt54g as robot brain

Andrey Mikhalchuk demonstrates how to hack a popular wifi router to have an rs232 interface (or two). The openwrt project allows us to actually use that powerful hack. Andrey did what few people did before: he added a micro servo controller and TING robot's done!

How can I add Wifi to my robot?

I'm new to robotics but have dabbled in Microcontrollers the last few years and develop software for a living. One thing I've been dreaming of doing for awhile is builting a blimp robot that is controlled over wifi, but I can't seem to find information on is how to connect microcontrollers to some sort of wifi interface. I'm hoping there's some sort of module somewhere that I can interface with.

Here's the plan:
