than using it alone. 2.1 Motion in of a land vehicle In most of the cases, navigation system is used to detect the position of an object. The general motion of a land vehicle is typically calculated by the values that are given by accelerometer and gyroscope. 2.2 Principle of inertial navigation sensors The principle of inertial navigation system is mainly related to Newton’s 1st and 2nd law of motion. The 1st law of motion is described that “changes in motion are caused by outside forces” and
Despite what some people may think, motorcycle roadracing is not only a highly strenuous sport, but there is much more involved than just twisting the throttle and turning the handlebars. There are a number of powerful forces working on the bike and the rider. There is, of course, the downward pull of gravity, friction between the tires and the track, and centrifugal force which acts to the outside of the turn. The key to cornering at high speeds is to perfect the lean angle of the motorcycle so
A student with a compulsive longing for the explanations of why and how things work is a science professor’s dream student. Thus, it would make sense for the first few steps within the science building to intensify that essential characteristic of its students by its very construction. The foyer of the science building evokes this sense of scientific wonder and rational thought through its methodical design, which is embodied at its center by a Foucault pendulum. The Foucault pendulum is named
Angular momentum and its properties were devised over time by many of the great minds in physics. Newton and Kepler were probably the two biggest factors in the evolution of angular momentum. Angular momentum is the force which a moving body, following a curved path, has because of its mass and motion. Angular momentum is possessed by rotating objects. Understanding torque is the first step to understanding angular momentum.Torque is the angular "version" of force. The units for torque are in
The Kallang River is the longest river in Singapore and it flows via the Marina Channel into the Marina Barrage a dam (Cornelius, V., 2008). According to the researchers from the (National Parks Board, 2009), the Kallang riverside park located on the side of this river which holds many recreations and sports activities such as fitness equipment and jogging and cycling tracks marked with distance markers. This cycling tracks leads down towards the Esplanade Park which is one of the oldest parks in
enemy miles away. It was the first drone of its time, using an onboard gyroscope that guided the drone to its location. The first test flight for the drone was on October 2nd 1918. The test failed because the drone flew too steep in the air, it stalled and eventually crashed. In 1916-1917 Elmer Sperry and Peter Hewitt developed an unmanned aircraft, known as the Hewitt-Sperry Automatic Aircraft. It was also piloted by gyroscopes and also with a barometer that could measure the altitude. The first
birds. The incidence VTOL UAVs was also during the same era, it was merely a stick with feathers, that when spun strongly enough, generates enough lift to go into vertical flight. Towards the end of the 15th century, Da Vinci developed the ‘air gyroscope’. This is regarded by many as the ancestor of today’s helicopter. Its principle of operation was turning the shaft to generate a force strong enough which enables it to spin, and eventually fly. In the 19th century, VTOL UAVs were the hottest and
left or right simply lean in that direction. When the Segway was first unveiled in 2001 it was the first ever self balancing electric vehicle.To remain upright the segway uses five gyroscopes, a built in computer, and tilt sensors which monitor the users center of gravity 100 times every second! For the record, a gyroscope is a device consisting of a wheel or disk mounted so that it can spin rapidly on an axis that is itself free to alter in direction. The segway has such good balance that it doesn’t
Einstein’s Theory of General Relativity originally came to him in 1907 while he was sitting in a chair in the patent office in Bern. Lost in thought, he began wondering what it would be like to drop a ball while falling off the side of a building (James Overdunn, Stanford Edu) Granting all this, he realized that the person who was falling would not be able to detect the effect of gravity on the ball whereas an observer could. Hence, he figured out the principle of Equivalence, that gravity pulling
Apple computer, Inc. is one of the largest tech companies in the world. The company was established on April 1, 1976, and incorporated on January 3, 1977. Apple computer had been using this name for the first 30 years then removed the word “computer” on January 9, 2007. Apple has produced a lot of innovative products and has successfully become one of the top leaders in the field of technology. Apple itself produces hardware which includes Macintosh computers, iPods, iPhones and iPads. In order to
Microelectromechanical Systems (MEMS) are systems that are designed on a micro metre scale and have become more popular as the demand for devices to get smaller has increased. The main uses of these systems are for sensors, such as accelerometers and gyroscopes and other such devices like microscopy and inkjet nozzles for example. There are many materials that can be used for MEMS as the cost of the material is almost eradicated due to the micro size of the systems being produced. This brings materials
at reducing physical demand, restoring the ability to generate basic movements in daily life and/or amplifying the human abilities of the user [1-3] Improvements in microprocessor capabilities, high-power electronics, multi-axis accelerometers, gyroscopes and advanced power systems has extended the use of these devices from clinical to real-world circumstances [1, 2] Earlier technologies focused on augmenting the abilities of able bodied users for industrial or military purposes. However, the intended
After this recent decade of advancement in robots, the question of how efficiently a robot makes decisions is still debated. Robots have various sensors that it takes into its central processing unit that influences its decisions. The development of gyroscopes allowed for the development of self-balancing robots and have given rise to modern day humanoid style robots. Robotic engineers can now design and teach robots various intelligent thought programmed patterns and skills to solve problems similar
The Hubble Telescope is the world’s first space-based optical telescope. The Hubble telescope received its name from American astronomer Dr. Edwin P. Hubble. Dr. Hubble confirmed an ever expanding universe which provided the basic foundation of the Big Bang theory. The first concept of the Hubble telescope came from Lyman Spitzer in 1946 who at that time was a professor and researcher at Yale University, Professor Spitzer believed that Earth’s atmosphere blurs and distorts light and a space orbited

are crucial to the underlying mechanisms of a driverles vehicle. The first and most recognizable would be a GPS unit, used to find the route the car would take. This technology would be enhanced with readings from tachometers, altimeters, and gyroscopes to provide a more accurate positioning of the vehicle. Lidar sensors would be used to identify lanes and the sides of the road by bouncing light off of the vehicle’s surroundings. Cameras would detect signs, pedestrians, and other possible obstacles
WWII, one of the bloodiest wars in history. The Germans and the Axis Powers were combating the English and US with the other Allied Powers. From 1939-1945 war raged on in Europe and in the Pacific. In 1939 proposals were made (not approved until later) by the Nazi’s to create two of the most destructive and advanced weapons of the time (Gatland). Thus, the V-1 and V-2 rockets were put into production. The V-1 and V-2 rockets were important to the German’s because they believed that these weapons
Uranium was discovered by Martin Heinrich Klaproth, a German chemist, in the mineral pitchblende (primarily a mix of uranium oxides) in 1789.Klaproth, as well as the rest of the scientific community, believed that the substance he extracted from pitchblende was pure uranium, it was actually uranium dioxide (UO2). After noticing that 'pure' uranium reacted oddly with uranium tetrachloride (UCl4), Radioactivity was first discovered in 1896 when Antoine Henri Becquerel, a French physicist, detected
CHAPTER 2 LITERATURE SURVEY 2.1 Falls : Fall is the major problem that causes death to the elderly people . it has became a major challenge to the public health care system for tackling these falling events. The world is ageing. People aged 60 and older make up over 11 percent of the global population, and by 2050, About one third of every person aged above 65 is affected by the fall and related health issues.. 2.2 Causes of fall : Falls are a manily causes due to psychological
In 2011, TED Talk released a remarkable video of a man named Dennis Hong designing a car for the visually impaired using robotics. As strange as this concept sounds, the advanced age we live in can make that possible eventually. According to the CNIB, about a half a million Canadians alone are either blind, partially blind, or lost vision over time due to natural decline. In Ontario alone, about 186,954 people are either blind or partially sighted. With that said, this is a problem for people in
