Robotics is the Magnum Opus of Engineering, It combines Electronics, Mechanical, Computing and also the toughest science know to mankind.... Wireless Networking!
Ethernet Networking itself is complex, A self healing, hack proof and plug-play Wireless Router has to be the first step to make safe robots.
Just imagine a Wireless Router or even a Internet Router as easy to tune as a FM radio, no entering numbers, no admin with browser. Just keep it in a room and all gadgets and computers form a fuzzy network, all by themselves. The very idea of technology is to make things simple, cost-effective and efficient.
The real need of robots now is to avoid Humans in Hazardous Environment. Right from Outer Space to working in a Plant with Toxic Chemical Gases, Even machinery and equipment that injures the limbs or damages the eyes.
