The Internet is a vast resource for robotic applications while the communication is centralized around an Ethernet module designed for direct access to the Internet. This article covers the case when the robot is based on Arduino board integrated with an Ethernet shield designed for an easier setup and configuration.
We live in a world of communications and in a constant process to transfer communication technologies to other platforms that can be used by intelligent machines like robots. In three steps can be built a powerful communication system by plugging the Ethernet module into the Arduino board, create network connections, and building the application for data transfer.
In this article, I make an overview of Ethernet shields Arduino compatible with different features including here standard shield, WiFi module already integrated in the shield or a combo pack with an Arduino board and Ethernet shield.
Arduino Ethernet Shields
With only few instructions a robot based on the Arduino board and Ethernet shield can be connected to the Internet.
A robot based on Arduino board can be connected directly to the Internet using a so-called Arduino Ethernet shield. With a minimum effort the TCP/IP connectivity is ready in minutes, while the shield is generally designed to support up to four socket connections at the same time. In the following are available a series of Ethernet shields with different features including here WiFi connectivity or used as a combo pack with an Arduino board included.
- Arduino Ethernet Shield R3 – the Ethernet Shield R3 allows development of TCP/IP applications Arduino board compatible for Internet connection. The shield includes a MicroSD card connector;
- Ethernet – collection of Ethernet shields Arduino compatible and with a wide range of features;
- Arduino Uno R3 + Arduino Ethernet Shield R3 Combo Pack – all in one kit with Arduino UNO and Ethernet shield for a fast connection to Internet;
- Arduino WiFi Shield – a shield that requires only a few instructions to start controlling your robot through the Internet;
- WiFi Shield V2.1 For Arduino – compatible with the Arduino board, the shield is a low-power WiFi all in one piece including here support for IEEE 802.11 radio and with full access to functionalities;
Tutorials and Guides
Tutorials and guides for a better understanding how a robot can be controlled remotely using an Ethernet shield.
The Ethernet shield is in the center of this article and together with Arduino board we can build an application for sending commands to a robot and receive feedback through a WiFi router. In this section of the article I made an overview of tutorials and guides prepared to understand and build the first application that uses Arduino board, Ethernet shield and Android, iOS, or a simple computer and an IP address for remotely connecting to a robot.
