Abstract
The Video Capturing Vehicle (VCV) is a robotic video capturing vehicle with full ground mobility. The
control of the robotic vehicle is achieved using Dual Tone Multi Frequency (DTMF) technique. The VCV is controlled
by a Remote Control System (RCS) which consists of a Personal Computer (PC) with a Graphic User Interface (GUI)
application interfaced via Universal Serial Bus (USB) to a DTMF generating circuit and an FM transmitting circuit that
sends DTMF codes via Radio Frequency (RF) link to the VCV robot. The robotic vehicle consists of an FM receiver, a
DTMF decoding circuit, a microcontroller circuit board and an Internet Protocol (IP) camera. Using the DTMF codes, the
direction and motion of the VCV, as well as the viewing angle of the VCV’s camera is controlled by the RCS. The robot
while moving, simultaneously captures video feeds using the IP camera attached to it and sends captured video feeds via
Wireless Local Area Network (WLAN) to which the PC at the RCS is initially connected to. The received video feed is
displayed on the GUI. This system finds application in diverse areas such as surveillance, viewing of human inaccessible
area, experimentation (monitoring health hazardous areas remotely), military applications as well as other industrial and
security pursuits
