Rocker bogie mechanism (mars rover) final year mini project final review paper BIRENDRA KUMAR PANDIT
The Rocker-Bogie Mobility system was designed to be used at slow speeds. It is capable of
overcoming obstacles that are on the order of the size of a wheel. However, when surmounting a
sizable obstacle, the vehicles motion effectively stops while the front wheel climbs the obstacle.
When operating at low speed (greater than 10cm/second), dynamic shocks are minimized when
this happens. For many future planetary missions, rovers will have to operate at human level
speeds (~1m/second). Shocks resulting from the impact of the front wheel against an obstacle
could damage the payload or the vehicle. This paper describes a method of driving a rockerbogie vehicle so that it can effectively step over most obstacles rather than impacting and
climbing over them. Most of the benefits of this method can be achieved without any
mechanical modification to existing designs – only a change in control strategy. Some
mechanical changes are suggested to gather the maximum benefit and to greatly increase the
effective operating speed of future rovers.

A gyroscope, not to be confused with gyrocompass, is a spinning wheel mounted on gimbal so that the wheel's axis is free to orient itself in any way. When it is spun up to speed with its axis pointing in some direction, due to the law of conservation of angular momentum, such a wheel will normally maintain its original orientation to a fixed point in outer space (not to a fixed point on Earth).
The relevance of this project is to determine the effect of gyroscopic reaction on bearings. We determine the reactions on bearing due to different spinning angular velocity of rotor and at different precision angular velocity of the system . This concept is useful in selection of bearing during particular application where extra load due to gyroscopic effect occurs on any system.
A device consisting of a wheel or disc mounted so that it can spin rapidly about an axis which is itself free to alter in direction. The orientation of the axis is not affected by tilting of the mounting, so gyroscopes can be used to provide stability or maintain a reference direction in navigation systems, automatic pilots, and stabilizers.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202
3. Gyroscope
DEFINITION :
A gyroscope is a device for measuring or maintaining
orientation, based on the principles of conservation of
angular momentum.
4.
5. History of Gyroscopes
1817. Johann Bohnenberger created the first know
gyroscope, calling it simply the “machine”.
1820. Pierre-Simon Laplace recommended the “machine”
be used as a teaching aide.
1852. Leon Foucault coins the name “gyroscope” when he
uses Bohnenberger’s “machine” in an experiment involving
the earth’s rotation.
1905 – 1908. The first gyroscope for marine navigation was
developed by German inventor Hermann Anschutz-
Kaempfe.
6. 1917. The “Chandler gyroscope” toy was invented by the
Chandler Company in India. It is still considered a classic
American toy.
During World War II, the gyroscope became the prime
component for aircraft and anti-aircraft gun sights.
1991. Charles Stark Draper Laboratory demonstrated one
of the first MEMS or “Vibratory” gyroscopes fabricated in
silicon.
7. Principle of Gyroscope :
Whenever a body is rotating in a plane(plane YZ) about an axis(axis
Ox) and a couple is applied on the rotating body across the axis of
rotation or spin in an another perpendicular plane(plane XY), the
rotating or spinning body starts processing in a third mutually
perpendicular plane(plane XZ).
8. Applications of Gyroscopes
A. In Aeronautics :-
1. Remote control flying devices, helicopters, some
hovercraft, some planes, etc. rely on gyroscopes to
prevent them from flipping over or going into a spin.
9. 2. Spacecraft rely on gyroscopes for orientation while
in space.
3. Aircraft and aircraft autopilots rely on gyroscopes to
account for changes in direction & altitude
10. B. In Naval field
1. Gyroscope are used in ships to maintain stability as
the effect of gyroscopic couple is on:-
(a.) Steering
(b.) Pitching
(c.) Rolling
11. C. In automobiles
1. Gyroscopic behaviour is used in the racing car
industry. This is because car engines act just like big
gyroscopes. Because of the gyroscopic forces from the
engine depending on whether the engine is spinning
clockwise or anti-clockwise the cars nose will be forced
up or down.
12.
13. 2. Wheels on motorbikes act as gyroscopes and make
the bike easier to balance (stay up right) when moving.
14. D. In electronics and gadgets
1. Gyroscopes are used in various fields nowadays such
as in smartphones, video game controllers, computer
mouses and presentation mouses.
