What better way to start experimenting with open source micro-controllers ( Arduino ) then by building your very own open source robot ( CC (SA -BY) )?
What to do with your SERB?
Features:
- Fully programmable using an Arduino Duemilanove micro-controller (or another micro-controller of your choosing).
- No need to solder.
- Choice of cutting options for acrylic pieces. (scroll saw, access to a laser cutter, purchasing pre-cut pieces)
- Easily expandable and modifiable with extra bolt holes and included breadboard.
- Dual ball bearing rear wheel.
- Up and running in 1-2 hours. (from kit)
- Open source design (build as many as you like)

Step 1: Parts & Tools
All bolts can be found at your local Home Depot. The other parts can be found online (I have included a link to my favorite source for each).

Step 2: Cutting Pieces
Please chose which steps to follow based on the cutting option you have chosen.
Option 1 (Purchasing Pre-cut Parts)
- Purchase a pre-cut chassis from oomlout.com’s store ( here ) ($60 including shipping to the USA and Canada)
Option 2 (Digital Manufacturing (ie. Ponoko ) / Access to a Laser Cutter)
- Download the laser cutter layout ( “03 SERB Ponoko Cutting Layout P2.eps” or “03-(SERB)-Ponoko Cutting Layout (P2).cdr” )
- Cut the files using Ponoko or on your own Laser Cutter (using 3mm, .118″ acrylic (sometimes sold as .125″)
Option 3 (Scroll saw and Drill)
- Download and print the PDF pattern (please choose the file corresponding to your paper size) 03-(SERB)-ScrollSaw Pattern (letter).pdf 03-(SERB)-ScrollSaw Pattern (A4).pdf(it is important to not scale the drawing while printing)
- Measure the ruler on the printout against a ruler you trust, if they do not match the pattern has been scaled and you need to look at your printer settings before reprinting. If they do match up, onwards.
- Glue the pattern to the acrylic sheet (3mm, .118″ (sometimes sold as .125″).
- Drill holes.
- Cutout pieces using a scroll saw
