The Robot Quartet is an art installation by Andres Wanner that features four marker-equipped 3pi robots working together to create drawings. The robots receive identical commands and draw repetitive patterns on the same surface.
You can see more pictures of the completed artworks on Andres’s website.

The node-pololumaestro project is a module for the Node.js platform that allows you to control a Maestro USB Servo Controller over its serial interface from a Node.js program. This module provides functions like
maestro.setTarget(0, 1500) and internally takes care of assembling the bytes of the serial command for you. The module was written by Owen McAree and was recently expanded by achingbrain. We always like to see our customers helping each other through projects like this!

In this video, Brian Patton demonstrates how to program an animatronic robot using a Maestro Servo Controller. He covers basic configuration using the Maestro Control Center and shows how to sync voice with servo motion using software from his company Robodyssey.

Customer Mike Kohn recently wrote to us about two of his projects that use Pololu parts:
This paper disk is marked with black and white patterns spread across four distinct rings and can store a total of 16 bytes of data. Mike decodes the data with one of our QTR-1RC reflectance sensors. Read more about “PAPER-ROM”…
This balsa wood airplane uses an ATtiny85 to interpret signals from a Syma S107 helicopter remote controller, and it uses our 5:1 micro metal gearmotor HP to spin its propeller. Read more about this airplane project…
Mike has documented many of his other software and electronics projects on his web site.

Shahmir Javaid tweeted about a tutorial he wrote that describes how he used a Raspberry Pi to control a Maestro servo controller in C. His tutorial documents the steps he took, including setting up the Raspberry Pi for UART, wiring, and programming. The setup is simple, and the code is provided.
A customer sent us a link to this instructable that shows how to make an automated XY table that can be controlled through the internet. It is constructed from T-slotted aluminum extrusions and uses an Arduino and jrk 21v3 motor controllers to drive the axes using a pulley system.
You can interact with this XY table by going to TeleToyland, which has a browser based interface that allows you to draw an image and watch the XY table reproduce your image in a sandbox.
