Arduino Controlled Servo Robot (SERB) using arduino

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?

• (here) – How to Add Obstacle Detecting Whiskers to Your Robot
• (here) – How to make 30 kits (Open Manufacturing)

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).

Parts List:

A bundle containing all hardware items can be purchased at oomlout.com’s store ( here ) ($120)

Nuts and Bolts:

• 3mm nut (x34)
• 3mm washer (x12)
• 8mm x 25mm bolt (x2)
• 8mm nut (x2)
• Skate Bearings (x2) ( VXB ) (these are standard skate bearings so they can be salvaged from a pair of roller-blades or a skateboard)

(all wire is 22 AWG solid I purchase mine through McMaster-Carr )

• 15 cm Purple (x2)
• 15 cm Black (x1)
• 5 cm Black (x2)
• 5 cm Red (x2)

Tools

• Screwdriver (x1) (Philips)
• Needle-nose Pliers (x1)

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
