Multi-robot systems are reliable and faster at searching and retrieving targets in times of crises as compared to single-robot systems. They are also better compared to manned missions as they are more resistant to hazardous conditions. In this work a method to deploy a swarm of robots to scan and retrieve the targets stuck in a disaster situation is deliberated. The multi-robot system developed is fault tolerant and follows a complete decentralized approach. In the proposed work, the basic elements in a real time search and rescue mission such as exploration of disaster area, target and obstacle detection, path-planning to reach the target in a coordinated way and tolerance for a few possible faults are accomplished using the 'weights based algorithm' and the prototype testing done mimics the real time scenario. Communication among the robots in the swarm is implemented by using X-bee modules. The robots search the arena till either all the targets are found or the entire arena is explored and update a common map which renders the approach a decentralized behavior.

The control methods for DC-DC converters should consider wide input voltage ranges and load variations to guarantee stability under wide operating conditions. The switching action of DC-DC converters makes them variable structure systems. Sliding Mode controller is a robust nonlinear controller that can be used for such variable structure systems. The general idea of the SM controller is to create a non-natural stable point by studying the system dynamics and then create conditions to turn on or off the switch. In this work, a forward converter topology that retains the features of a buck converter has been designed and developed. The converter output voltage is maintained constant by using a sliding mode controller under load variations. A systematic design procedure for continuous conduction mode of forward converter has been implemented. The converter and the sliding mode controller was simulated and analyzed under PSIM and MATLAB/SIMULINK environments. Hardware implementation of an analog SMC controller has also been developed for a 30W forward converter model.

Swarm robotics is based on the characteristics displayed by the insects and their colony and is applied to solve real world problems utilizing multi-robot systems. Research in this field has demonstrated the ability of such robot systems to assemble, inspect, disperse, aggregate and follow trails. A set of mobile and self-sufficient robots which has very restricted capabilities can form intricate patterns in the environment they inhabit

Ka Manickavasagam, M. Nithya, Priya, Ka, Shruthi, Ja, Krishnan, Sa, Misra, Sa, and Manikandan, Sb, “Control of distributed generator and smart grid using multi-agent system”, in 2011 1st International Conference on Electrical Energy Systems, ICEES 2011, Chennai, Tamilnadu, 2011, pp. 212-217.[Abstract]


The electric power system is an enabling infrastructure that supports the operation of other critical infrastructures and thus the economic well being of the nation. It is therefore very important to design a smart grid for resiliency and autonomous re-configurability in the electric power grid. For the operation of any power system, its control architecture consisting of hardware and software protocols is very essential for exchanging system status and control signals. This is accomplished by Supervisory Control and Data Acquisition (SCADA) systems. Current trends to control and monitor the operation of electric power systems are however moving towards the use of an automated agent technology using a multi-agent system which replaces SCADA system. The objective of this paper is to design and model a multiagent system which consists of Distributed Energy Resource (DER) agent, Data Base agent, Control agent and User agent. DER agent is modeled using MATLAB/SIMULINK. The simulation results presented in this paper show the seamless transition from grid connected to an island mode when upstream outages are detected. This denotes the capability of a multi-agent system as a technology for managing the microgrid operation.
