  3. IntroductionProblem Statement • So many advances have been made daily to vehicles in order to increase the demand of vehicle buying and trading. • Some vehicle features include power locks, keyless entry, tracking systems, and even headlight curvature for the road. • In addition to that, the car will also be used as a military intelligence device. • It will allow the death toll for car bombings to decrease, due to the fact that the car will be able to direct it’s own path and not need someone to physically drive it. The goal of this project is to build, design, and field demonstrate an autonomous vehicle that will navigate through a preprogrammed course while avoiding obstacles. The car will automatically follow the given path, with the use of global satellite positioning, and without human maneuvering reach the desired goal.

  4. IntroductionObjectives 1) The car should follow a given path. 1.1 The car should follow the programmed path. 1.2 The car should follow any path with the use of GPS. 1.3 The car should reach a desired destination. 1.3.1 The car should reach the end of the course. 1.4 The car should avoid all obstacles. 1.4.1 The car should avoid unforeseen objects in it’s way. 1.4.2 The car should adjust accordingly when avoidances in the road are reached. 1.5 The car should be able to operate without the use of human maneuvering. 2) The car must be a reliable source of transportation. 2.1 The car must be durable. 2.2 The car must be safe. 2.3 The power consumption must be low. 2.4 The car must be user friendly.

  5. Introduction ConstraintsAssumptions and Limitations Constraints • The project budgeted must be under $600.00. • The project must be completed in time. • Software limitations of the OOPic Assumptions and Limitations Assumptions The device will be retrieved and acted upon by the OOPic controller. Limitations It can only work in an open space where the GPS module can pick up a signal. It can only travel along the programmed obstacle course.

  6. IntroductionOperating EnvironmentIntended Use and Users Operating Environments This project is intended for outdoor use only. When driving through tunnels, advanced sensors will be used as tracking devices such as GPS may not work. Intended Use and Users This project was designed to be operated by anyone who owns a vehicle, driver’s license. For military use, military officials will program the car to travel a given path.

  7. Feasibility Analysis

  8. IntroductionNeeds Analysis

  9. IntroductionStandards K. Standards and Considerations Standards for Remote Control driven Toys at 27Mhz. (2) • radio services operating below 30 MHz are permitted to operate on any frequency except for certain designed restricted bands within the 30MHz spectrum • frequencies below 30 MHz where wavelengths are greater than 10 meters, the long stretches of electrical wiring can act as very efficient antennas permitting the RF energy to be radiated over the airwaves • The FCC conducted emission limits for radio services below 30 are reduced by 13 dB for comparison to the limits Sec. 97.307 Emission standards (3) • Emissions resulting from modulation must be confined to the band or segment available to the control operator. Emissions outside the necessary bandwidth must not cause splatter or key click interference to operations on adjacent frequencies. • No amateur station transmission shall occupy more bandwidth than necessary for the information rate and emission type being transmitted, in accordance with good amateur practice. • No angle-modulated emission may have a modulation index greater than 1 at the highest modulation frequency.

  10. End Product Description

  11. Concept Adjustments • The base vehicle is already designed and working. • The steering will need to be reworked for better range of motion. • We may need another microcontroller. • We may need to lighten the vehicle by reducing the amount of battery packs or reducing the size of the battery packs. • We will need to test the usability of the Sharp IR sensors as compared to other, maybe better sensors. • Sensor placement will be a key factor. • We will need to move breadboard components to a pcb to ensure proper connections are made between the various circuitry.

  15. The Project Ethics Ethical Issues • The first ethical issue for having autonomous vehicles that are monitored by GPS is safety, accuracy, and the loss of human employment. • Automated vehicles, controlled by GPS, impose a safety issue. Humans must rely on the use of GPS to maneuver them throughout traffic. • They must gain a sense of trust for the GPS system to get them to and from there homes safely. • In addition to that, there lies an ethical issue of the accuracy of the system. • If the GPS system is affected in some way due to weather conditions or a loss of informational data, this could cause the use of the GPS to be ineffective. • The system must be detailed and have a route of the city that must be updated according to new highways and roads, as well as an internal map of short cuts and back roads. • Creating a vehicle that is hands free could impose a problem for human jobs. • It could increase the number of jobs that a lot of Americans use as their source of income. • Creating the autonomous vehicles could also decrease the need for people in the military if the car advances military intelligence.

  16. The ProjectEthics B. Determine the Stakeholders The stakeholders are everyone who has a driver’s license, active men and women in the military, the families and friends of people in the military, and people who drive cars as their occupation daily. C. Determine the Options • Best Extreme – Create automobiles that only have a monitoring GPS system. • Worst Extreme- Create an automobile with GPS that incorporates all the driving functions needed to go anywhere in the United States. • Compromise – Create an autonomous vehicle with a GPS monitoring system that is for personal and military use only. Use will be restricted to work vehicles unless owner is self-employed. In addition to that the car will incorporate a self drive mechanism.

  17. The ProjectEthics D. Application of Ethical Theories • Utilitarianism supports the best extreme, as it would generate the greatest benefit for the greatest number. If there was just an automobile with a monitoring GPS system, a lot of people would not have the concern of losing their jobs, the safety issue, and accuracy of the system. They will rely on GPS tracking to get from one place to the next, but use their sight to maneuver the car accordingly. The people that have driving jobs will love the idea of using the GPS system, but they will have job security with this choice and it will make their job a little easier. Instead of following a map they can rely on the GPS system. • Ethical egoism supports the worst extreme, because it does not take into consideration the people who drive for a living. It supports the interests of the organization and takes no thought into the concerns of the issues of safety that Americans may encounter. If the car is fully autonomous and controlled by GPS, one day with advancements the world could solely rely on robotics.

  18. The ProjectEthics • Ethics of care would defend the compromise option, because it would allow an option for the military to decrease the number of deaths that are related to vehicle bombings. In addition to that, it would take into consideration the feelings of those Americans that do not feel like driving on an everyday basis. It also includes the feelings of those who do not want to lose anyone to war while caring about the want of people to do other things while on their way to work.

  19. The ProjectEthics F. Choose, Defend, and Justify the Best Option Based on the Analysis Above. The best option is the compromise option because it takes out the safety and accuracy concerns for those who do not trust a computer based system. It also defends the people who have loved ones and friends in the present day war that do not want to lose them to vehicle bombings. Lastly it gives the everyday human who may be in a hurry to work the option to use the features of a fully autonomous GPS controlled car that allows them to get safely to work while finishing their morning tasks, such as drinking their cup of coffee in the morning, applying makeup, or catching the morning news.
