Arduino Robot

Some days ago RS Components published the 5th and last video in a series of 5 video tutorials about Arduino Robot. After learning how to get started, to remotely control the robot, avoid obstacles and follow lines, you can now learn how to use the TFT screen to deal with images and how to make music and listen to it with the Robot.

In the video below David  and Xun show examples and give your tips on how to navigate through these features: (more…)

Following lines, going to the rescue with Arduino Robot – Video Tutorial

ArduinoRobot

 

Once again Xun and David in this fourth video tutorial on the Arduino Robot released by RS Components, are exploring one of the most used techniques in Robotics: following a line, just like factory robots do to get an orientation when they carry objects from one place to another without human intervention.

Watching the video you’ll learn how to create a racing track drawing a black line over a white surface and understand how the different sensors read data that will be used to feed a PD algorithm: (more…)

Playing with sweets, photoresistors and Twitter

Thursday, November 7th, 2013

TweetSweet
Martin sent us this fun project called TweetSweets, inspired by Labby’s twitter-enabled candy machine

How does it work? Easily explained:

- User1 sends a tweet with #givejacksweets
• Processing searches for the hashtag, sends a tweet thanking them and passes ‘sweets’ to Arduino
• Arduino activates sweet dispenser for 0.5 seconds
• Photoresistor detects when User2 collects them, and passes to Processing
• Processing takes a photo of User2 and tweets this to the User1
• User1 and User2 both smile :)

I’ve also cobbled together bits of code from other sources, including: (more…)

Controlling water heater with Arduino Yún

Thursday, October 31st, 2013

SmartBoiler

This week I’m going to introduce George Koulouris who loves playing, testing, making with others  especially at the ‘Petit Fablab de Paris’ where he thinks is a  great place to do exactly that!  He’s been experimenting with the Arduino Yún focusing on his main interest: the integration of technology to everyday objects. The following post was originally posted on his blog Read  other guest posts on Arduino Yún.

——————
The Motivation
I have two small problems in my house. An ever-increasing electricity consumption bill and a girlfriend which likes to take hot baths at unpredictable times during the day.

Until recently, we left our water heater switched on, 24/7. But then we took a look at our electricity counter readings. Needless to say, we switched it off immediately! An old water heater can indeed make the electricity counter wheel spin fast, very fast…!

So we started switching it on and off whenever we needed to take a bath. The problem was that we weren’t always at home and the water took almost an hour to heat-up! So I decided to connect it to the internet! (more…)

Avoid obstacles, create strategies with Arduino Robot – video tutorial

infraredRobot

In this third video released by RS Components, Xun and David are going to show you how to deal with ultrasonic range finders, infrared range finders and a trick using ultrabright white LEDs and LDR sensors and in general how to use different technologies to detect obstacles in the way of the Arduino Robot.

In some way ultrasound and infrared operate in the same way: a signal is sent, it bounces on objects and the received echo is used to estimate the distance. With ultrasound, the speed of sound and the time difference between the sent signal and the received one is used, while infrared is more direct as it gives a stronger or weaker reflection depending on how far the signal travels. The estimation of the distance is done via software.

Logo and Remote control your Arduino Robot – Video tutorial

Mbanzi_robot

 

RS Components released the second video focused on the first steps with the Arduino Robot with Massimo Banzi, David Cuartielles and Xun Yang:

In this video you will see where to find code examples on the IDE. The robot library comes with two folders named “learn” and “explore” with examples on how to use the software to program the top board – this is the board you will mainly interact with while the motor board runs its original firmware.

One of the first examples of coding on the Arduino Robot is called “LOGO” which is very similar to an early educational programming language that controlled a virtual turtle moving across the screen with simple instructions. This time however, instead of having a small virtual turtle running on a screen, we have a robot that can respond to commands demonstrating a basic example of movement.

“LOGO” invites users to interact with the robot using the keypad to tell the robot whether to move forwards/backwards or to turn left/right. The program can store a series of commands that will then be executed one at a time. (more…)

RSComponents - ArduinoRobot

Last year, Arduino and RS Components, collaborated in the creation of 10 video tutorials focused on the Arduino Starter Kit. Some months ago they were released in Creative Commons and are available also on our Youtube channel.

During Maker Faire Rome, at the beginning of October, RS Components together with Massimo Banzi and David Cuartielles, unveiled the release of other five exclusive video tutorials introducing the Arduino Robot and exploring various characteristics of this new open-source hardware on wheels.

Getting started with Arduino Yún video tutorial

Getting Started with Yún

 

The Arduino Yún is an Arduino board unlike any other. While programming it is very similar to the Arduino Leonardo and uses the same processor, the Atmel ATmega32U4, it also has an additional processor, an Atheros AR9331, running Linux and the OpenWrt wireless stack. Programming the 32U4 via USB is identical to the Arduino Leonardo. Once you’ve configured the Yún to connect to your WiFi network, you can program the 32U4 via WiFi as well.

We prepared a video to explain how to take the first steps with the board, you can watch it below and then keep reading the Getting Started Guide:

 

 

Hands on: the Arduino Yún’s Bridge

Thursday, September 5th, 2013

arduino yun - handson

The other day, we gave you an overview of the Yún’s hardware. Today, we are going to talk about the Bridge library, describing how it facilitates communication between the two processors. The Arduino Yún has two different processors on-board: an Atheros AR9331 running Linino (a customized OpenWRT GNU/Linux distribution maintained by Dog Hunter) linked through its serial port with an Atmel ATMega32U4 (the same processor as the Leonardo).
The Bridge concerns itself with communication between these two parts of the Yún.

The Bridge is made of two different parts
One part, written in Python, runs on the GNU/Linux processor and has three functions:

  1. it executes programs on the GNU/Linux side, when asked by Arduino.
  2. it provides a shared storage space, useful for sharing data like sensor readings between the Arduino and the Internet
  3. it receives commands coming from the Internet and passes them directly to the Arduino

The other part of Bridge is the library that runs on the 32U4. The library allows you to access the Linino parts of Bridge through your sketches. (more…)
