The current work reports of an obstacle avoidance and object tracking algorithm integrated and tested on robot. The system is designed with high torque geared DC motors and it has a payload capacity of up to 3 kg. The robot is fully autonomous and it is designed to patrol high security/hazardous zones and dynamically report any suspicious activity which when observed initiates an alarm to the security for further action whiles it continues to track and report the suspect. This has a major advantage over conventional CCTV systems in terms of cost and memory requirements and would not require constant human supervision. The robot proposed hereof uses wheel-encoders, ICbased Gyroscope, IR Line Laser, and spy camera as the basic sensing elements. It also has a smart charging feature which makes it energy efficient.
