This robot doesn’t look too good, but it servers its purpose, it proves that it can be done at home. The bot its based on Qwerk, a robot processor board very popular these days. The Qwerk is made to control myriad robots; it can control up to four motors and sixteen servos, while interfacing to sensors with eight analog ports, sixteen digital I/O, and an i2c bus. It also has two USB sockets so that robots may include a USB webcam and a wireless 802.11 network adapter.
