Design and implementation of a robotic vehicle with real-time video feedback control via internet

This paper illustrates on an approach to control a robotic vehicle using internet as communication medium between user and robotic vehicle. Conventionally wireless robots have the drawbacks of limited working range, limited frequency range and limited control. But internet can overcome these limitations with the help of DTMF decoder IC and a preprogrammed microcontroller IC that control the movement of the robotic vehicle according to output sent from DTMF decoder. The outstanding feature of this implemented robotic vehicle is use of tilt sensor that keeps controlling of the robotic vehicle unaffected upon tilting more than 90 degree.
