UNDERWATER AUTONOMOUS VEHICLE
Autonomous Underwater Vehicles (AUVs) are programmable, robotic vehicles that, depending on their design, can drift, drive, or glide through the ocean without real-time control by human operators. Some AUVs communicate with operators periodically or continuously through satellite signals or underwater acoustic beacons to permit some level of control. AUVs allow scientists to conduct other experiments from a surface ship while the vehicle is off collecting data elsewhere on the surface or in the deep ocean. Some AUVs can also make decisions on their own, changing their mission profile based on environmental data they receive through sensors while under way.

BRAIN CONTROLLED UNMANNED VEHICLES
Unmanned Vehicles (UV) are becoming promising means both for military and civilian applications to provide more accurate, inexpensive and durable information than ground surveillance systems. Human thought commands are acquired using Electro-Encephalogram (EEG) cap or head set. Firstly, EEG signals are very hard to track. To control the UV, EEG and Eye-Blinking signals are needed. In this system, we have planned to use simple unipolar electrode to record EEG signal from the forehead and the Brain-Computer Interface (BCI) acquires, processes and classifies the signal to primarily control a robotic car and a quad copter UAV. The two signals like meditation and attention along with the eye-blinking signals are extracted by BCI. We propose to develop Unmanned Aerial Vehicle flight control system with different brain signals, since controlling of UAV is faster by mind than by controller(joystick)and provides easy maneuvering in dangerous environments. Here, our thoughts are quickly converted to actions. It is chosen to be a Quad-rotor system because of its total controlling capability to facilitate from take-off to landing in regions with space constraints. Thus, we are implementing our custom quad-copter controlled by the Human Brain.
Experimental Setup of BCI Drone
High Altitude Ballooning (HAB) is one of the rising and internationally accepted Space Activity. Ever since its development for the use in weather reporting, the HAB have find their usefulness for scientists/educational Institutes, Independent Researchers, Science & technology groups etc to get the real time exposure of working in Near Space Region. Being a Low-cost activity, the project marks its flexibility by allowing scientists to design their own payloads. Ranging from Basic Sciences to study the upper atmosphere and earth’s topography, its usefulness can be stretched in biomedical applications as well.
MULTI ROLE COMBAT ROBOT
The aim of our project is to design and fabricate a motorized operated multipurpose device. With this device several operations can be performed. They are as follows:
- Unmanned defence (gun shooting)
- Bomb detection
- Pick and place
- Video analyzing
The analysis of the flight of insects, birds and ornithopters is difficult because there is limited aerodynamic theory applicable for the large amplitude unsteady wing motions. Furthermore, the complex wing shapes and wing motions encountered in insect and bird flight entails complex aerodynamic interactions. A systematic theoretical and experimental study has been pursued by the senior author for the past several years to gain a better understanding of the aerodynamic, dynamic and mechanical problems of flapping wing flight.The primary intent has been to establish a strong technical base necessary for the development of the ornithopter as an alternative to the helicopter. The helicopter is best suited for hovering flight and suffers greatly reduced efficiency as forward speed is increased. On the other hand, the ornithopter can achieve hovering flight, albeit with much more mechanical complexity, but promises high efficiency in forward flight. The method of attack for this study of the ornithopter has been to depart gradually from the conventional aircraft configuration so that the large body of knowledge accumulated in the development of the airplane could be applied to the study of the ornithopter. In future we are going to be used drones for security and surveillance purpose. But the main idea is that to make the concept of Bi-wing flapping mechanism which can be used for surveillance and security purpose. The advantage of Bi- wing mechanism is that over the drone is that it will fly like a bird so human can’t able to detect easily but the drones can easily detect by humans.
GESTURE CONTROLLED MICRO AERIAL VEHICLE (MAV)
The use of natural gestural interactions for communications with an autonomous Micro Aerial Vehicle (MAV).They could be inspired by human interactions with other people and the environment to understand the user needs (For example, hand signals for marshalling helicopters and directing infantry personal, or just natural reactions like putting arms around the head to protect from an immediate danger),or be inspired by human and animal interactions in the relationship between a human and a autonomous Unmanned Aerial Systems UAS.
HYBRID PARA MOTOR GLIDER
Paramotor is the generic name for the harness and propulsive portion of a powered paraglider ("PPG"). There are two basic types; foot launch and wheel launch. Foot launch models consist of a frame that combines powerplant, caged propeller, and harness (with integrated seat) attached with quick release buckles to the operator's back. Wheel launch units include some type of cart, usually having 3 or 4 wheels, with seats for one or two occupants. Two attachment points connect the left and right risers of a paraglider. Paramotoring is not to be confused with the similar, but different, Powered Parachute which is generally much heavier, more powerful, and has different steering. Jet Paramotor when done for scientific purpose requires proper mission planning and execution. Based upon the objective, the guidelines are defined.

MULTI TASKING UNMANNED AERIAL VEHICLE
Its an unmanned aerial vehicle autonomously controlled by a pilot within his ARDUPILOT 2.8 popularly known as APM 2.8 flight controller in the market which is an open source software. The APM flight controller is connected to GPS system which has home locking system in it. It also has a TELEMETRY connected simultaneously to the UAV or any USB controlling device knows as ground module and air module. It has GESTURE CONTROL in it as well as BRAIN CONTROLLED. The gesture setup is controlled by human hand. Brain Control is controlled by human brain in which the concept of neurology is used in it.
MODELING AND CHARACTERIZATION OF FLIGHT SIMULATOR – future work
In the field of simulation work, it could proceed to an extent that, simulate with arbitrary values of the Pitch, Yaw and Roll rate in aircraft equation of motion. The simulation results recorded various strategic points in the simulation indicate and validate the fact that the simulation is working in the expected environmentregarding the desired flight situation in the expected flight pathregarding the given arbitrary values. Also, in this proposed experimental work, it is observed that for an arbitrary value, the flight path obtained is agreeing with the theoretically computed flight situation.
CLUSTER UAV FOR STEALTH – future work
Quadcopters are a useful tool for university researchers to test and evaluate new ideas in several different fields, including flight control theory, navigation, real time systems, and robotics. In recent years many universities have shown quadcopters performing increasingly complex aerial manoeuvres. Swarms of quadcopters can hover in mid-air fly in formations and autonomously perform complex flying routines such as flips, darting through hula hoops and organizing themselves to fly through windows as a group. There are numerous advantages to using quadcopters as versatile test platforms. They are relatively cheap, available in a variety of sizes and their simple mechanical design means that they can be built and maintained by amateurs. Due to the multi-disciplinary nature of operating a quadcopter, academics from several fields need to work together to make significant improvements to the way quadcopters perform. Quadcopter projects are typically collaborations between Aeronautical Engineering, computer science, electrical engineering and mechanical engineering specialists.
PASSENGER DRONE (DRONE TAXI) – future work
The future of passenger drones remains uncertain since this technology is so new.Innovation in aerial drone technology, and in aerial traffic coordination, control, and collision-avoidance could result in rapid proliferation of passenger drones for civilian travel. Several companies are exploring the use of passenger drones as air-taxis and for air-ambulance services. Passenger drone developers are working to overcome many challenges,including noise,small useful load,short flight times,airspace regulations,and scarce data on both safety and general operations.
MINE DETECTION ROBOT – future work
Many precious lives are lost in war field due to bombs and landmines thus we develop a robot that can autonomously detect landmines and bombs and diffuse them and attack enemies, drop medicines and for search and rescue operation. These robots are controlled either by remote control or semi-autonomous or fully autonomous by computer. Some such systems are currently in use, and many are under development. Defence, Security and Surveillance Robots are much more robust than their hobby grade or educational counterparts.
SOLAR POWERED UAV – future work
Unmanned solar powered aircraft offer a unique set of advanced capabilities and have set general aviation records for longest continuous flight and greatest sustained altitude. However, the application of solar powered flight to small scale solar powered unmanned aerial vehicles (UAVs) has seen sparse research activity and is only partially explored. The use of solar power as an energy resource allows small scale UAVs to carry heavier, more powerful sensor payloads, and can extend flight times to over 24 hours, thereby achieving multi-day flight. This work focuses on recent developments by the Centre for Distributed Robotics on a four meter wingspan solar UAV designed for low altitude aerial sensing applications. Highlighted in this paper are aspects of airframe, propulsion, and electronics hardware design as well as experiments that quantify the solar power system and airframe performance.
