Some projects that we build fulfill a genuine need for a new piece of hardware or software that will make life easier or fix a common problem. Other projects, on the other hand, we do just because it’s possible to do. [Gilchrist] has finished work on a project that fits squarely in the second category: a web browser that runs exclusively on an Arduino Uno with an ethernet shield.

The Arduino can serve plain-text web pages to an attached LCD and can follow hyperlinks. User input is handled by a small joystick, but the impressive part of the build is on the software side. The Arduino only has 2KB of RAM to handle web pages, and the required libraries take up 20KB of memory, leaving only about 12 KB for the HTML parser/renderer and the LCD renderer.

The Arduino browser is a work in progress, and [Gilchrist] mentions that goals for the project include more robustness to handle poor HTML (the Hackaday retro edition loads flawlessly though), a terminal, and WiFi capabilities. To that end, maybe a good solution would be using the new ESP8266 chip to keep things small and inexpensive?

Another Robot, another App(lication) of Arduino. The user [shreks7] built up an Android App for controlling the robot wirelessly and stream live video off an android phone placed on the robot.

The robot has an inbuilt wireless router and two brush-less DC motors and runs on a power source of 26-30V(depends on the requirement) power supply.

The robot streams live video back to the app and can be used for navigation.
Also there is a console for Windows to control the robot and debug it .

It uses Arduino Mega 1280 + Ethernet Shield + Pololu Motor Driver (It is by far the best one i have used) + Belkin Router & Two Android Devices .

There is also a [video] where you can see the robot in action.
