For our robot we will need the following parts and tools:
(If you haven’t read the project outline you can do it here)
- Parts
- WRT54GL router or similar. Since our “routerbot” OS is nothing else then a bit modified OpenWRT Linux you can find the list of compatible models here: http://wiki.openwrt.org/TableOfHardware. I was using exactly WRT54GL that is available for $50 AR here: http://www.newegg.com/Product/Product.aspx?Item=N82E16833124190 . This would be the most expensive part, but hopefully you already have compartible model.
- 1 x SSC-32 servo controller $40 - http://www.lynxmotion.com/Product.aspx?productID=395&CategoryID=. This is the second most-expensive part
- 2x continuos rotation servos, $13 each - http://www.lynxmotion.com/Product.aspx?productID=429&CategoryID=38
- Self-locking nylon bands of different sizes. $1-2 in Target.
- Two-sided really good adhesive tape. I’m using the one made by 3M I bought in Target. $3-5
- Rubber bands – I got mine in Whole Foods on register. You’ll need approx 10 of those. FREE
- 2 x CD disks. I personally prefer Verbatim for burning backups, so for this project I used Memorex. AOL disks you can pick up in Best Buy would work great too. FREE
- 2 x continuos rotation servos $14 each
- 9.6 1600 mAh rechargeable battery pack – get one in Warmart or find it in one of your kids’ R/C toys. They typically power the engines in the toy itself.
- Coaster wheel – I had one at home, you can get one from Home Depot or Target for instance. See the pictures for approximate wheel size
- Data cable, $2 - http://www.lynxmotion.com/Product.aspx?productID=256&CategoryID=44
- 1x Battery Quick Connect cable, $2.50 - http://www.lynxmotion.com/Product.aspx?productID=65&CategoryID=. Actually this one may be better: http://www.lynxmotion.com/Product.aspx?productID=497&CategoryID=44
- 5mm jack connector exactly the same your router power supply is connected to the router with. I don’t remember where I got mine. If don’t have one just solder the wires from battery directly to the power connector of the router.
- Video system (optional)
- Video camera – get one on ebay for $20
- 2x servos, $13 each - http://www.lynxmotion.com/Product.aspx?productID=78&CategoryID=38
- 1x servo bracket, $8 for pair - http://www.lynxmotion.com/Product.aspx?productID=326&CategoryID=87
- 1x servo hinge, $6 for pair - http://www.lynxmotion.com/Product.aspx?productID=261&CategoryID=75
- Bunch of wires
- Optionally you may want to use 10-pin header and 10-pin connector (I made mine from IDE cable)
- Tools
- Soldering iron. If you plan to do more electronics later better get rework station. (I personally like Aoyue 968 for its great price/performance ratio)
- Glue gun. This tool is optional, but it will help you a lot, so I’d recommend getting one. It is just $2 in Michaels + $1 for clue sticks in a dollar store.
Order all the stuff you’re missing and proceed to the next part.

Very good article! I plan to start building one of these very soon. It should be noted that people may not want to buy a new router for this because they are likely to get a newer version which will not accept an OS flash/change.
I’ve got my router ready and about to order servos, can’t wait!
