A smaller robot is the Wifibot 4G, a miniature 28x30x20 cm robot weighing only 4.5 kg, running on 9.6V NiMH batteries for 1.5 – 3 hours. The Wifibot uses four independent motors to control its movement. This robot employs various networking capabilities to support advanced operational capabilities, including autonomous or tele-operated functions, relay (utilizing client or mesh networking and routers) or swarm, deploying ad-hoc or mesh networking.

Fitted with an integral 32 bit PowerPC 405EP processor running Linux operating system, WifiBot uses embedded Ethernet, USB, I2C bus and RS232 interfaces. Built-in networking support include WiFi 802.11b/g link with seamless roaming capability, mesh network support, wireless LAN client, and router.
