Wirelessly-controlled robot with PIC and nRF24L01+

Posted by Jamee on 10 September 2013

In this video, Amjad Al-Ahdal demonstrates his wirelessly-controlled robot with multiple modes that he programmed in C. The robot contains a PIC18F2455 microcontroller, an nRF24L01+ transceiver, a SN754410 motor driver IC, a Pololu wheel and encoder set, and two 100:1 Micro Metal Gearmotors. Its controller has a homemade keypad, another transceiver, a 9DOF sensor, and a serial 16×2 LCD screen.

The Robot Quartet

Posted by Kevin on 10 September 2013

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.

Node.js module for Maestro servo controllers

Node.js module for Maestro servo controllers

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!

Paper ROM and balsa wood airplane

Posted by Jon on 26 August 2013

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.

Dagu Rover 5 controlled by a Raspberry Pi

Posted by Zeeshan on 23 August 2013

Pololu forum user chrisptx posted this video of his Dagu Rover 5. He is using a Raspberry Pi as the main controller and sending signals to a TReX Jr Dual Motor Controller for drive control.

This rover is controlled by a Samsung Galaxy S3 smartphone, which uses its web browser to send commands to the Raspberry Pi in Javascript.

Controlling a Maestro in C using a Raspberry Pi

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.
