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.

Internet Controlled T-Slot XY Table

Posted by Grant on 22 August 2013

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.

Tron Suit Costume

Posted by Kevin on 19 August 2013

Swap_File posted a write-up of this Tron-inspired costume on the Adafruit forums. A pair of Wixels — one in the disc and another in the jacket — helps to enable wireless control of the suit’s lights and displays.

The costume was featured in a Wearable Wednesday blog post on the Adafruit blog.

Brute Force Car Radio Code Solver

Posted by Jon on 19 August 2013

Forum user Christian, writing from Germany, posted this video of an automated system he built that pushes buttons on a car radio (Becker Mexico CD 876) as a brute-force method to determine its radio code. In his system, he uses our Mini Maestro 12-Channel USB Servo Controller and 10 servos to extend rods of wood to press the numbered buttons on the radio console. You can read more about his system in this forum post.

The setup had already run for 3 days straight, but Christian expects it to take another 30 days to finish entering all 10,000 codes. We look forward to hearing back from Christian once it finishes.

Pololu Wixel with SD Card as USB Mass Storage Device

Pololu Forum user VolAnd, writing from St. Petersburg, Russia, posted about an app that turns a Wixel into a USB SD card reader. The Wixel identifies itself as a mass storage device, and basic read/write operations are working. His goal is to create files with the Wixel that he can then read from a PC. You can read more or get the app from his forum post.

This Wixel app and many others are available in our listing of community-contributed apps on the forum.

Robotic Car - A Simple Way to Build a Model

Posted by Jon on 15 August 2013

In this video, Brian Douglas uses our MinIMU-9 and Zumo Robot to show how to build a control system model for a robotic car without first knowing all of the different internal workings of the car.

Brian hosts a YouTube channel where he uploads various control system videos that are intended to supplement first year classroom instruction. You might also be interested in some of his other videos: This video demonstrates closed loop control of a robotic car, and the videos in this playlist explain how to use a gyro with MATLAB/Simulink and Arduino.

Lunokhod, which means “Moon Walker” in Russian, was built for a space museum in Prague and is a miniature version of the first remote-controlled moon rover. It is uses 8 of our 298:1 Micro Metal Gearmotors and an Arduino Nano and can be remotely controlled by museum visitors.
