Bot Bench I'd Rather Be Building Robots
The mailman brought some shiny new toys this morning, one of which included the all-new Dexter Industries WiFi sensor. I don’t have all the technical details for this one yet, but like the NXTBee, it uses the NXT’s RS485 port for high-speed communications.
It has a clip to hold a 9V battery on the back, the red and black wire you see is for the 9V battery connector.
This module has a lot of very cool features:
- Radio Protocols: 11b/g/n (pretty much all of them)
- Security: All the standard crypto methods, including WPA/WPA2 and WEP and many more.
- Network Protocols: on top of the standard UDP and TCP, it can also act as both a web client and server; your robot can go online!
I will reveal more details later (I simply don’t have any more), for now the somewhat blurred out picture above will have to do.
Don’t you mean the NXTBee?

Thanks, Tim, I’ve fixed the article!

So, are you planning to connect it to the NXT’s battery (I use rechargeable) via some wire, or an external power source? I would like a comparison, drivers, and Wi-Fi on-brick! Not sure what it would take to host a site, though.
I am not sure what you’re looking to compare. As for the power source, I will just use a 9V battery.
Couldnt’ you use the extra power on port A to power it

Sure I could, anything is possible. I am currently working on a very small treadmill for my hamster George. I am hoping to harness his running energy to power the sensor. Currently my main focus is on the driver, power is an issue for another day 🙂
So could it make the NXT surf the internet? Like facebook or online data logging? Or is it just the other way around?
Either, i presume
Maybe @Xander knows more
You could. I daresay implementing a full-blast API for browsing Facebook would be very cumbersome. The sensor has a built-in HTTP client that you can tell to go to specific URLs, that includes FB 🙂
