INTRODUCTION:Ø Biomimesis is the scientific method of learning new principles and process basedon systemic study, observation and experimentation with livings animals andorganisms for practical solutions to future technologies.
Ø Fromthis class I become familiarize with some of the methods like hydrophobichydrophilic glass, bullet train in japan of establishing principles through observations,experimentation and constructing model of living organisms.Ø Becauseof this class I became confident enough to tackle scientific problems. Now I amconfident enough to capture ideas from biological species and to project itinto technological ideas.Ø So,from this study I can now identify basic principles hidden within complexbehaviours. The basic conjecture is that evolution identifies in the long runoptimal solutions, hence animals have achieved a perfection of function thatcan be studied and replicated.
Ø Varioustopics like material science, biomimicry of different things like Shinkansentrain of japan like king fisher, hydrophobic glass like lotus leaves was reallyinteresting. Ø Fromthis course some general knowledge like how japan reduced the noise ofshinkansen was really great.Ø Fromthis course I also learned about different materials and its types.
The mostimportant thing is that the implantations of biology into technology in spiteof being a science student which was unknown to me. Now I can figure out thingsin and around us which are biomimicry of natural things.Ø Whilesearching the web I found different things which we know that exists but wedon’t know that is a biomimicry like whale wind turbine, bionic car, Velcroetc.
which are actually very interesting.Ø So,this class really help me to identify the beauty of nature and its applicationinto technology. MERCEDESBENZ BIONIC CAR:In the mid 1990s,mercedes benz planned to design a car that have some special charecteresticslike-· Aerodynamic · Safe· Efficient · Maneuveravle · Overaching theme Manyresearchers have done various research to found the concept of box fish whichis a small topical coral reef fish.
Just like other fish box fish also havesome charectersetics like entirely encapsulated in a squarish or traingualr,lightweight,rigid,bony shell which looks like a honey comb. It also locked eyes withmedusa.Boxfishhave a unique carapace and shape.
Because of that uniqueness engineers startlooking at its charecterstics. Box fish thought to have important andimpressive hydrodynamic charecterestics. Boxfish are blocky, broad, roundedshape box fish.
But it was reported to have exceptionally low drag. Thecarapace supposedly had unique,inherent,self correcting stabilizationproperties which directs the flow of water in such a way that the swimming fishis kept on course even in high force waves. Because of all these chrecteresticsbox fish was choosen as model. STRENGTH OF BIONIC CAR:Boxfish has low flowresistance though it has a cubersiome appearnce.
it has drag cofficient of 0.06.Penguins have coefficient of 0.
19.Some specificcharecterestics includes:· Great rigidity· Low weight· Lower fuel consumptionthan traditional cars.· Diesel engine of 103kw· 140hp engine· Torque is around 1600rpm· 0-60 in about 8 sec· Top speed of 190km/hr.· Rear wheel partially fitted with plastic tomreduce weight.WEAKNESSOF THE CAR:Ofcourse, just because something seems like the perfect design in the naturalworld, doesn’t necessarily mean it works out that way in industrial design. Youmight have noticed the distinct lack of Bionic Car-shaped vehicles on the road,which is probably because a 2015 study found that the shape of theboxfish didn’t reduce drag at all and actually made it more unstable – great for a box fishwith 50 million years of evolution to perfect the art of being a boxfish, lessgood for a people carrier.Mercedes Benz completely fails to understand the concept of box fish.
Interpretation about the fundamental hydrodynamic profile of the fish waswrong. Some researchers contend that the boxfish body shapes do notparticularly excel at drag reduction. Instead of minimizing instability itactually promotes. Because of this the car concept was contradictable.Boxfish swimming paradox was successfully solved by some researchers. There was aconflict between the supposed flow patterns influenced by the boxfish’s bodyshape and day to day needs of a fish living in a coral reef system.
The shapeof the body molded by bony carapace was thought to function as a built-instabilizer. Box fish works on the mechanism of vortex lift which is the samemechanism responsible for stabilizing the insanely dynamic flight of delta wingair craft.POSSIBLE APPLICATION OF HUMAN:Possibleapplication of this technology is MICRO UNDER WATER VEHICLE. It is aelectromechanical devise with rigid body propelled by a oscillating tail finand steered by a pair of independent side fins. The oscillating motions of thefins are independently controlled by PZT biomorph.
It is actually driving fourbar mechanisms for motion amplification. The researchers want to build amicrobotic fish. The fish must have the capability of sustained autonomousswimming. the researchers thought to use this in marine organism sensing, underwater shipwreck explorations, in pipe inspections, and in forming underwatersensor networks.
CONCLUSION:a) So, bionic carconcept may be a failure but it bought a new era in the history of biomimetics.Bionic cars have may be lots of weakness but it has some exceptional strengthwhich can easily beat up the modern car. In this era where there is hike ofpetroleum price we need some vehicles which are fuel efficient. Moreover, thisidea can be implemented in making marine vehicles which consumes lots ofdiesel. Navy can use this as under water vehicle to spy underwater.o So, concept of biomimicry is really a boon to thesociety.
