1. This paper presents a feasibility analysis of developing an ultra-small bio-mimetic flying machine using the most advanced engineering technologies that exist today.
2. The core part of this project includes leading edge technologies such as MEMS, IC’s and wireless technologies.
3. Here aerodynamic theory and forces explains how things should fly according to their characteristic length scale. 4. MEMS actuators can be made in the same scale of insect wings and “flap” at >100Hzat very low power input.
5.This flapping frequency is within the range of wing flapping frequency of many common insects in the millimeter dimensions.
6. This paper explains the use of micro battery, simple CPU, wireless receiver.
7. MEMS actuators can all be fitted onto a Si chip of ~1mm2 area, which weight around ~1mg, which is the typical weight of millimeter scale insects, a bio-mimetic flying machine can be realized.
8.our contribution towards this project is done with the help of IIT researchers.. Here we are using the
chemical reaction as a source of energy to make a robot to fly(spyro).. The SPYRO is powered by a chemical reaction. A monopropellant is injected into the body, causing a chemical reaction that releases a gas.
9.The gas pressure that builds up pushes a piston in the fuselage. This piston is connected to the pivotally coupled wings, causing them to flap rapidly.
10.Some of the gas is exhausted through vents (holes) in the wing and can be used to change the lift on either wing so the vehicle can turn.
11.The main application of this Spyro is for defence purpose ie, as a bomb detector ,use of wireless camera ,as an agent to help in naturaldisaster area, and to detect the illegal immigrants(terrorists) and to attack them etc….
A ‘Flying Insect Robot’ can certainly be realized if sufficient funding is available
Keywords -micro aerial vehicle; thermal actuators; flapping Wing. INTRODUCTION:-
Bio-mimetic robots have recently gained much research interest due several new technology advancements that will eventually make them functional and useful to the general public:
1) “smart materials” such as artificial muscles and PZT which will offer new alternatives for actuation of mechanical mechanisms;
2) much more precise, efficient,
and lower cost servo motors which will allow the control of robotic movements with more precision and accuracy;
3)IC chips that allow advanced control algorithms to be implemented in a much smaller footprint than 10 years ago;
4) micro/MEMS sensors that could be embedded in robotic systems with much more functionality at smaller footprint, and with lower power consumption.
Research on such robots is aimed at the advancement of ordinary robots to adapt the natural environment. On the other hand, the advancement of MEMS technology has allow engineers to fabricate much smaller mechanical actuators, gears, and systems than 15 years ago. This has led to some interest for various groups world wide to develop millimeter to centimeter scale bio-mimetic robots, e.g., a bio-mimetic swimming fish or a bio-mimetic fly. Another interesting example of a bio mimetic flying robot is the flapping wing Micro Air Vehicle (MAV), which has been an exciting research topic since a few years ago . MAVs are projected to find applications in surveillance, rescue, and military missions. Currently, many researchers in both biology and engineering fields have great interest in...
