I'm starting to play with the opcodes. I'm not hw hacker at all and btw since the vacuum cleaner is new i need to stay on the "reverse hack" side of the force. Are there any wireless ip camera around that could work with batteries? Is there a way (a passtrough the serial port) that could drain enough power for a usb wireless webcamera? thanks! Hi,

I know the bump sensors use an optical interrupt switch which is mounted on the mainboard, i'm wondering if there is a way to modify that to work with a IR or ultrasonic sensor any input would be appreciated thanks Jeremy(P.s love the book way cool) hi has anyone replaced the bump sensor on the romba with non-contact sensor, with out using a external microcontroller.

I hope it will work and not drain the battery too much in practice. I still have no clue on the question on connecting up the router and Roomba serial lines; some people put resistors on the RX/TX lines and I don't understand why...

I'm sorry for the double posting; there is another question I have, how to power the router? It is supposed to take in 5V at up to 2A, is it safe to draw this from the Roomba battery (14.5V) using a DCDC voltage converter? AIUI, that would be putting 0.7A through the two miniDIM pins, not sure if that's safe, and how well the battery will take it either. If one would use an extra battery to power the computer, what is the best choice? Hi! I’m sorry for the double posting; there is another question I have, how to power the router?

I realize that you probably elaborate on this in the book, unfortunately I was unable to find a seller shipping it to Europe (I'll be glad for any tips). I want to control my Roomba 505 over WiFi, so I'm buying an Asus WL500Pv2 now - it seems that both the Roomba's serial port and the router serial port have TTL RX/TX, so is it fine to just connect them directly without any middleman electronics? What should I do with the UCC/GND pins, just leave them unconnected? Thanks in advance! Hi!

I have finished this year my electronics engineering and I have been working in the robotics department the whole year. My last task before leaving is prepare some exercices for the next years students using a Roomba. I would like to know what exactly the serial port sends to the roomba, just to try to do the same with a PIC or an FPGA, to be able to put a code into the roomba and not control it with the PC. Another great thing it is if there is someone using visual c++ instead of Java because we don't do anything with Java. Thanks a lot! Hi, I am a 23 years old guy from Barcelona.

I have an older Roomba model 4275 that I want to use for a project for mobility-impaired elderly people. I want to adapt the return-to-charging-base system to work on a small electric cart. The user would press a button on the base station and the cart would drive itself over to the base station. Does anyone have experience doing this or know where to point me? Thanks!

But fortunately, Asus has been producing an even better router called the Asus WL-500gU, which I think is basically the same as the WL-500GP, but is fully functional. <a href="http://mightyohm.com/" rel="nofollow">MightyOhm</a> has written up a great set of articles on <a href="http://mightyohm.com/blog/2009/05/building-a-wifi-radio-part-10-building-the-box/" rel="nofollow">how to get the Asus WL-500gU working with a custom OpenWrt Linux distro and with serial drivers for things like Arduino and Roomba</a>. He was building a WiFi Radio, but all the techniques he uses work great for adding a WRT-based Linux box to your Roomba. Hi Cordell,

I wanted to connect a webcam and USB missile launcher to a wireless router and make an internet connected patrolling robot to shoot my cat when I'm in the office. However, I never even got started because of the limited choices in wireless routers out there with USB ports. i cannot find the one from the book the WRTSL54GS, after a year searching on ebay. So I tried buying an Asus WL-500gP but the wireless firmware doesn't work once you install linux, there are tons of posts on this. You can replace the wireless board but I didn't want that hassle. Do you know of anyone that has successfully hooked up Wireless Roombacam with a modern router? and if so I would love to know what version or model. Thanks, great book I can't wait to get started.

Perhaps it got set to a different baud rate? What version of Roomba do you have? Hmm, I’m not quite sure. Perhaps it got set to a different baud rate? What version of Roomba do you have?
