...DARPA Challenge The define problem in this challenge is building an autonomous vehicle capable of traversing 175 miles off road in the desert in less than 10 hours. There are many major problems and obstacles in this challenge that could happen. There can be over heating in the electrical equipment and the engines, and also traction control. Also some obstacles that could be faced are some landscape problems such as all the sand and dirt in the desert, also traction control can be an issues. The group thinks that speed limit you would need to go to complete the course in the allotted time would range from 20mph to 30mph. In consideration you would also have to think about the course and its problems. Such as all the wild life that the vehicle would come across, also anther thing to think about is all the stops and turns in the route and the conditions of the landscape. In this challenge the vehicle wouldn’t be going a constant speed, so you would have to keep that in mind. Some strategies to avoid problems and obstacles that you can take to mind is modifying your vehicle by putting four wheel drive, cooling systems for all the electronics that produce heat, putting in a GPS system, putting in sensors and cameras also reducing the weight of the vehicle. The disadvantages of the route information that we would be receiving would be no exact route. The route would be in the middle of the desert so there for there are no roads. Anther disadvantage is the vehicle is only limited...

...Unit 1 Assignment1: DARPA Challenge 1. How would you define this problem? What are the major problem components, and what obstacles do you foresee? -Finding a way to operate through an unknown course with no interaction by the builders. Weather, equipment failure and unknown terrain changes could all become obstacles that will hinder the ability to finish the race on time. 2. How fast do you need to go to complete the course in the allotted time? -An average speed of 17.5 MPH would be acceptable. Top speed should be somewhere around 50 MPH if conditions are good enough to do so. 3. What is the fallacy of considering the above average speed – what do you need to consider? -Exceeding above a nice steady speed of 17.5 MPH places more risks with unknown weather and road conditions. You would need to consider the forecast for the day and road conditions to match. 4. What strategies can you use to avoid obstacles -Radar, GPS, cameras to detect obstacles around the vehicle and Ladar. 5. What are some disadvantages of the route information you receive, in terms of the vehicle driving the route? -Not knowing the distance between 1 GPS location and the other, and not knowing if the coordinates given are going in a straight path or curving off to one side or the other. 6. What strategies can you use to prepare your vehicle for the route once you receive the information? -If possible the best thing to do would be to try and pre-determine what path the vehicle is taking...

...called the Advanced Research Projects Agency (ARPA) within the Department of Defense to compete with the USSR’s advancements in technology. Soon the Advanced Research Projects Agency became the leader in science and computer technology. Later, in 1962 Paul Baran of the RAND Corporation was hired by the U.S. Air Force to do a study in order to find a network that could be used as a military defensive strategy in response to a nuclear military attack. Baran's finished document described several ways to accomplish this. His final proposal was a packet switched network. Between 1968 and 1972 the BBN had control of a contract awarded to them by the Advanced Research Projects Agency later renamed the Defense Advanced Research Projects Agency (DARPA). BBN had hubs in 4 relatively close University on the west coast including University of California Santa Barbara, University of Utah, University of California Los Angeles, and Stanford University. These schools were all connected with a...

...Defense Advanced Research Projects Agency (DARPA), U.S. government agency administered by the Department of Defense. It was established in 1958, in reaction to the successful launch of Sputnik by the USSR, as the Advanced Research Projects Agency. Although DARPA is only one of many military agencies administering research and development funds, it has been crucial to the development of several important technologies, especially military computers and the Internet. It funds a high percentage of all artificial intelligence research in the United States, as well as significant projects in microelectronics, materials, and behavioral science.[1] DARPA's mission is to maintain the technological superiority of the U.S. military and prevent technological surprise from threatening our national security. DARPA programs focus on high-risk research with that will have payoffs that could provide dramatic advances in military capabilities. Each DARPA office manages a large portfolio of programs.[3] DARPA’s original mission, inspired by the Soviet Union beating the United States into space with Sputnik,[2] was to prevent technological surprise. This mission has evolved over time. Today, DARPA’s mission is to prevent technological surprise for us and to create technological surprise for our adversaries. [2] By focusing on high-risk research that could provide dramatic advances in military capabilities, DARPA maintain its mission which is to prevent any new technological attack from any...

...THE INTERNET Although you may already be familiar with its popular designation as the “information superhighway”, the Internet is usually a collection of computers, connected to a variety of means, to share information across vast distances. The Internet is what called a metanetwork, that is, a network of networks that spans the globe. It's impossible to give an exact count of the number of networks or users that comprise the Internet, but it is easily in the thousands and millions respectively. The Internet is also what we call a distributed system; there is no central archive. Technically, no one runs the Internet. HISTORY & DEVELOPMENT • In early 1970 – Defense Advance Research Project Agency (DARPA) of United States sponsored a research project that will design and develop an advanced mechanism for facilitating the flow of information between distributed computers. • Advance Research Project Agency (ARPA) funded the initial creation of the packet-switched network called the ARPANet. • Several other universities started joining the ARPANet and it reached a point when it had to be divided into two parts: 1. MILNet – for the military 2. ARPANet – for the non-military • By mid 1980’s – ARPANet had grown to more than 200 linked network with thousand of computers. • Recognizing the potential of ARPANet, a major network of research, education, and communication, the National Science Foundation (NSF) developed the NSFNet. • Different backbone...

...Darpa Challenge When creating a vehicle such as the one mentioned in this challenge, a lot of thought and consideration has to be accounted for. First the vehicle has to be able to travel at least 175 miles in 10 hours, the first thing that should be noted is the gas mileage. There are no gas station in the dessert so it has to have a fuel efficient way of traveling. The next obstacle established in the challenge is the terrain the higher-quality graded dirt with winding rocky-mountain passes and a tunnel. So, there’s loose dirt mountains and a tunnel all things that can cause the vehicle to lose grip of it terrain, lose control of the direction it wishes to go and also one’s sense of direction as though the location is a dessert and everything better much looks the same for miles. The last major obstacle pointed out in the challenge is the various speed limits which in turn could hinder the time of arrival if too many mistakes are made during the race. With using a combination of speeds ranging from 5-50mph the driver would have to travel at the least 17.5 miles in one hour using those speed limits. The fallacy of considering the average speed posted in the challenge is that there could be lots of wind the day of the race that is one does not carefully drive could easily be blown of track driving on that loose dirt. Ways of preparing the vehicle for this race would be to if possible find shortcuts or detours that guide us around the dangerous obstacles and also help us to...

...1. This problem is hard to define because with today’s technology it would not be that difficult to complete. Major problem components would be not knowing the GPS way points, the RDDF, or the speed limits until two hours prior to the start. It will be a definite obstacle to make sure that during that two hour period that the information is correctly entered into the computer to guide the autonomous vehicle. 2. On average the vehicle would have to travel at seventeen and one half miles per hour (MPH). Although, at times that speed will have to be adjusted to a higher rate of speed for times when slower speeds are necessary. 3. Considerations for the average speed would be the narrow roads, the cliff drop off, as well as other landscape obstacles. Whenever possible, the speed would need to be adjusted to more than seventeen and one half miles per hour (MPH) to allow for the times that the average speed cannot be achieved. 4. Strategies to avoid obstacles would include large all terrain tires and a computer monitoring system which would include views of the outer vehicle. An over- ride system would be in place to allow a person to operate the vehicle, by remote, in case of emergency. 5. The disadvantages of this vehicle driving the route are numerous. This includes, but is not limited to, narrow roads, sharp turns, and dangerous cliff drop offs. The biggest disadvantage will be the loss of the GPS signal. 6. Strategies to prepare...

...Darpa Challenge The problem is creating a vehicle with good handling on dirt and in heat without compromising speed and gas efficiency. I will not know how many way points there would be, and the degree of mobility that would be needed or weight/ height limits we may encounter. We have a general idea of the terrain but we do not have full information on it. I am looking at a speed limit of 20-25 miles per hour. It is assuming that the majority of the course does not happen on trails with set speed limits below 15 miles per hour. When considering the speed limit, I took into account possible tire changes, rest room breaks, breaks to re hydrate and eat, and slower portions of the course such as turns or unstable terrains and unexpected stops. Keeping a smaller vehicle design will help with turns, gas consumption, weight/height/width restrictions on the course, Using a general all terrain tire will help with most terrain that maybe encountered. Learning strategies for driving in a dessert such as, releasing a certain amount of air from a tire helps with traction in sand. Having a spare set of tires, as well as specialized tires for extreme terrain. It will be hard to fully prepare the vehicle for maneuverability and driver safety if we are unsure of what kind route the driver has to take. A straight route with few turns would not need a roll cage, where as tight turns or going along side a plateau would require one which adds weight. We can prepare tires accordingly, adjust...

...Essay A driverless car, also known as a self-driving car is an autonomous car which can perform the actions of the human being, as if a man were driving a traditional car. We can say that the car is independent of the human as the car only needs to be programmed with the destination. The mechanical part of the vehicle is held by the car its own. Moreover, to function, the car has some specific technology, for example laser, radar, GPS and computer vision. An example of an approved case of self-driving cars can be Google’s. In 2011 the state of Nevada was the first jurisdiction in the United States to pass a law concerning the operation of driverless cars. This law was turned into effect by March 2012 and the Nevada Department of Motor Vehicles gave the first license for a self-driven car in May 2012. This license was given to Google’s car which was in this case a Toyota Prius. Google got involved with this issue as it is trying to develop technology for driverless vehicles. In addition, the project is currently being led by Google engineer Sebastian Thrun, director of the Stanford Artificial Intelligence Laboratory and the co-inventor of Google Street View. To develop this system, Google also had to hire 15 engineers. This topic about self-driving cars involves also other issues such as hardware and software, social and ethical issues and the social impact. As regards hardware and software involved, it integrates Google Maps with various hardware sensors and artificial...

...Accidents happen every day, which consists of terrifying situations in an individual’s life and there are hundreds or thousands of accidents involving automobiles. A known fact is that most number of people has no survivals as they do not get to hospital in time after their car accident. The 2010 national Automobile census, mentioned that more than 90% of reported accidents were caused by driver and less than 10% was due to outside or car problems. As the advances of technology increases, so does the danger to people. This is due to there being production of faster cars that are more powerful, therefore increasing the chances of danger. The famous futurist Norman Bell Geddes said that “Your grandchildren will snap across the entire continent in 24 hours on a new kind of highway and in a new kind of driverless car that is controlled by the push of a button," Some say his idea was what inspired the creation of the Interstate Highway System. Few years ago, the driverless cars were seen as just science fiction, an imagination that was only accomplished in movies and novels. However it is close to being a reality that will be soon experienced. Currently, technology is so close, as our cars are technologically advanced enough to be able steer themselves. Moreover, the cars can also accelerate and brake to sustain a safe driving distance from any cars ahead and also detect and avoid crashes with other cars on all the sides. With this much technology advancement, making the cars...
