ACKNOWLEDGEMENT

At the outset we would like to thank the Management of Jodhpur EngineeringCollege and Research Centre, Jodhpur

For the wholehearted Co- operation and guidance extended them, which made our

Project possible Words often fail to express ones inner feeling of indebtedness toones benefactors. In fact words are not proper media for this purpose. The some

difficulty hunts which he owes to his reverend and kind guides and number of

other persons.

We wish to express my heartfelt thanks to Mr.Prema Ram Chaudhary( Asst.

Professor) for his support and guidance during our project we would like to thankthe Mr. S.N. Garg (Chairperson of the Mechanical Department) and

Mr. O.P. Garg(Co-Chairperson of Mechanical Department).

Last but not the least we are indebted to in valuable support of our family and

friends who were always there for our help.

ABSTRACT

The Unmanned Rovers of future are being designed for the warfronts andresearch purposes for the terrains where human access is remote anddangerous. These are used to maneuver rough terrains and are controlledby satellites. To help them in this advent gyroscopes are employed on themsuch that these rovers are balanced in all aspects of maneuvering and cansped off without stopping or getting stuck. The gyroscope not onlymaintains the balance but also helps rovers to get off the ditches or bumps.RUDRA is a concept for such an application of the gyroscope.

INTRODUCTION

RUDRA is designed on the concept of gyroscope is designed for helpingthe rovers getting out of ditches or uneven roads just by applying a simpleconcept of conservation of angular momentum.

Inphysics,angular momentum, moment of momentum, orrotational

momentum is aconservedvectorquantity that can be used to describe the

overall state of a physical system. The angular

momentum L of a particle with respect to some point of origin is

where ris the particle'spositionfrom the origin, p = mv is itslinear

momentum, and X denotes thecross product.

A mechanical gyroscope is essentially a spinningwheelor diskwhoseaxleis free to take any orientation. This orientation changes muchless in response to a given externaltorquethan it would without the large

angular momentum associated with the gyroscope's high rate of spin.Since external torque is minimized by mounting the device ingimbals, itsorientation remains nearly fixed, regardless of any motion of the platformon which it is mounted.

MATERIAL

The chassis will be manufactured in wood as wood is the cheapest materialavailable and easy to process according to the use. Its availability in themarket is no problem at all and its available in various qualities.

The tools required for it are easily available and a low cost.

MANUFACTURING

Carpentry will be employed to process the wood into the requireddimensions and fevicol will be used as the adhesive for binding the intricateparts manufactured separately.

TYRES

Tyres will be supporting the chassis and help the rover to freely roll on the

surface whenever required.

The tyres will be 6 inches in diameter and 1 inches thick in order to supportthe light weight chassis.

GYROSCOPIC DISC

It is a wheel which will rotate by gyroscopic motors and revolve around theaxis of precession, with the help of horizontal shaft welded with the vertical

shaft which acts as the precession axis. The horizontal shaft on which thegyroscopic discs are mounted act as spin axis.

The top most horizontal disc will rotate anticlockwise and the bottom discwill rotate clockwise and need to be parallel to each other.

These both act together to produce required couple.

GYROSCOPIC MOTORS

The gyroscopic motors will be attached to the horizontal shafts to which thediscs will be attached. It will give 5000 RPM at 12V to the discs.

TORQUE MOTORS

They will be attached to the vertical shafts which the will rotate in its ownaxis the top torque motor will rotate in anticlockwise direction. And thebottom torque motors will rotate in clockwise direction.

They will provide 30 RPM at 12V.

CONCLUSION

Uses for gyroscopes are increasing with the number of devices that require

guidance and control. Although the basics of the gyroscope are grounded in the

laws of physics and can never change, the technology is evolving. Mechanical and

electrical methods for providing the spinning mass that makes the gyroscope work

are gradually being replaced by ring lasers and micro technology. Coils of thin

optical fibers hold the key to compact, lightweight gyroscopes that might have

applications in navigation systems for automobiles. The gyroscope is such a simple

but sophisticated instrument for keeping so many tools in transportation,

exploration, and industry in balance that, seen or unseen, it certainly has a place in

the future.
