Arduino is very rich in its shields so there is another fast and great project – WiFi controlled Arduino robot. The platform is pretty simple – mainly made of wood. Interesting part is that Arduino is equipped with WiShield from AsyncLab’s that allows controlling bot remotely via TCP.
Robot platform can be controlled via Zipit or joystick. And of course it can perform standard movements autonomously. Project may be a great start to get used to programming WiShield that may push projects to a new level.
