1. Get the Parts and tools
One of the project goals was keeping it in a very tight budget. So before you actually order anything please look around, possibly you already have the parts or can borrow them from your friends. But first please make sure you have read the Routerbot v1 project outline. For our robot we will need the following parts and tools:
- 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 you can find via Froogle WRT54GL search or on eBay. I’ve bought mine for $40 after rebate on Newegg.com, for instance. This would be the most expensive part, but hopefully you already have compatible model.
- 1 x SSC-32 servo controller $40 available from LynxMotion.com. This is the second most-expensive part and it is unlikely you have it at home already.
- 2x continuos rotation servos, $13 each available from LynxMotion.com
- Self-locking nylon bands of different sizes. $1-2 in Target.
- Double-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
- 9.6 1600 mAh rechargeable battery pack – get one in Warmart or find it in one of your kids’ R/C toys. If you have kids most probably you already have one.
- 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. Borrow it from your friend’s office chair – they typically have 5 of those, he won’t notice one missing
- Data cable for $2, again from LynxMotion.com. See, I’m trying to save on your shipping charges.
- 1x Battery Quick Connect cable, $2.50, LynxMotion. Actually this one may be better
- 5mm jack connector exactly the same your router power supply is connected to the router with. I don’t remember where I got mine, most probably from RadioShack. If don’t have one just solder the wires from battery directly to the power connector of the router.
- Video system. It is actually optional because it will transmit to your TV. If you want to see what your routerbot sees in a web browser proceed directly to Routerbot v2 project.
- Video camera – get one on ebay for $20. You can pay more and get one with night vision. The performance of those cameras is much better then regular ones.
- 2 x regular servos for $13 each to pan&tilt the camera available from LynxMotion.com
- 1x servo bracket, $8 for pair from LynxMotion.com
- 1x servo hinge, $6 for pair from LynxMotion.com
- Bunch of wires. If you don’t have them open a piece of radio electronics you no longer need and you will find lot’s of them inside. RadioShack is another provider of this kind of stuff.
- Optionally you may want to use 10-pin header and 10-pin connector (I made mine from spare IDE cable and an old computer mainboard)
- Soldering iron. If you plan to do more electronics later better get rework station. (I personally like Aoyue 968 for its great price/performance)
- 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 glue sticks in a dollar store.
- Rotary tool like Dremel will make your life alot easier and creativier. I highly recommend having one in your household.
Order all the stuff you’re missing and proceed to the next part.
