Up for sale is an awesome little open source robotic arm! Just add an Arduino or other controller and you have a fully functioning mini factory robotic arm! Open source code is available for Arduino, Beaglebone Black, and Raspberry Pi.
This kit includes: 1ea - Wood kit containing all of the pieces that make up the main structure of the robotic arm 4ea - High Quality & Torque 10 Gram Digital Servos, not the cheap, blue, analog 9 Gram servos that others provide in their kits 4ea - Servo Extensions 9ea - M3 x 6mm Screws 10ea - M3 x 8mm Screws 5ea - M3 x 10mm Screws 7ea - M3 x 12mm Screws 4ea - M3 x 20mm Screws 10ea - M3 Hex Nuts 4ea - Rubber Feet 1ea - Printed list of links to websites containing the assembly instructions, example source code, and other resources to help you make the most of your meArm.
The items that you will need to supply are a micro controller of your choice such as an Arduino, Beaglebone Black, or Raspberry Pi, wiring, power supply (batteries), and possible a prototyping board.
The material thickness is 1/8" Baltic birch plywood. Fully extended, from the back of the base to the tip of the clamp is about 13-1/2" long. At it's tallest point, the arm is about 6-1/2" tall and the clamp reaches a maximum of about 5-1/2" high. The width of the base is about 3-3/4" wide. The clamp is about 3-1/2" when open and about 1" wide when closed.
Before laser cutting the arm, we cover the wood with a layer of protective masking tape so the wood doesn't get smoke damaged. The result is a spectacular looking and functioning robotic arm once fully assembled!

Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.
To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzed reviews to verify trustworthiness.
The product comes with assembly instructions for the mechanical parts, and they are fairly straightforward. It also comes a link to the arduino code. The mechanical parts are made of wood - they smell like a mesquite BBQ until you take off the tape.
However, there is no information on how to set up the circuitry. In the product image there's a circuit, which I assume corresponds to the given arduino code.
I made a question on this product asking what joystick module SpierceTech uses in the image, and they answered by linking to their website, which was deleted by amazon (can't link to other websites). I bought some joystick modules and hooked up the circuit as per the image but it didn't work.
There are a couple tutorials online and that's how I got mine working. Of course, there is no information on how to calibrate the servos, so you will have to look online too. Also, one my servos died.
Good product. Crap instructions. Doesnt tell proper calibration methods. Could have been documented much better. After i built as directed i tested with minimal success. Required complete disassembly to properly calibrate.
