Dynamic map generating Rescuer offering surveillance robotic system with autonomous path feedback capability

This paper presents an efficient design and implementation of a map integrated Surveillance-cum-rescue robotic system which can provide assistance during the accidental occurrences like earthquakes and structural collapses. When destructive events like quakes and mine collapses happen, often the victims do not get instant help to communicate with the outside world. An automated as well as manually operated robotic framework can be proven very useful in rescue operations and disaster management. The explicit design of the robot proposed here is meant to provide a definite map of the traversed area dynamically and it can also follow a specific map to reach a destination. Consequently, an HMI (Human Machine Interface) has been developed to control the substantial movement of the navigator from a moderate distance. Effective sensory modules and a stable control mechanism have been developed with the provision of consistent video feedback. In addition, the system is provided with an intelligence to detect human existence based on audio-visual feedback and an efficient self-protective design. The most unique feature of the system is if in any case the communication link with the host breaks down, the robot would return to the initial place following the traversed pathway which avoids the risk of losing the device. The system has been tested in different set-ups under several challenging environments and the results obtained affirm its reliability.
