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 and make equip it accordingly.

7. MTBCF stands for mean time between catastrophic failures. What kinds of failures do you anticipate in the testing phase?
-Vehicle failure due to the extreme heat in the desert. System failure of the electronics in the vehicle. GPS figuring out the correct path and failure when going through the tunnel(s).

Darpa Challenge

...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......

Darpa Challenge

...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...

Darpa Challenge

...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,......

...GS1140 Tuesday 7:20pm Instructor K. Fitch October 7, 2014 The DARPA project The DARPA headquarters was founded the year of 1958 in Arlington, Virginia by our very own president Dwight D Eisenhower. They have a total of 240 employees, and has an annual budget of 2.8 billion. DARPA stands for Defense Advanced Research Projects Agency. That is not the information I want to bring to your attention. The information I want you to know is about the DARPA challenge (The driverless car). From what I researched, the purpose of this vehicle is to travel into disasters that human engineering couldn’t bear to enter. The driverless vehicle must perform thee various tasks: 1. Drive a utility vehicle at the site.2. Travel dismounted across rubble.3. Remove debris blocking an entryway.4. Open a door and enter a building.5. Climb an industrial ladder and traverse an industrial walkway.6. Use a tool to break through a concrete panel.7. Locate and close a valve near a leaking pipe.8. Connect a fire hose to a standpipe and turn on a valve. I personally think it is impossible to build, for the simple fact that I would not even know where to start. While writing this essay, I was thinking of ways to engineer such a vehicle. I couldn’t come up with no analysis to such a challenge, then it hit me. What was said in the article I what Mr. Fitch been teaching us all along. The lesson of the original challenge [DARPA Grand Challenge - driverless cars] is that persistence pays.

Management Information System Chapter 3

...CHAPTER 3 - CAN TECHNOLOGY SAVE SOLDIERS' LIVES IN IRAQ? Few areas demonstrate the need for effective information systems more than warfare. Poor communication and inefficient systems don't just waste money; they put soldiers in harm's way and increase their risk of being injured or killed. Though the U.S. Army has made great technological strides in recent years, many of those new technologies have not translated to better safety and more accurate flow of information in the combat zone. Some of the struggles of the U.S. counterinsurgency effort in Iraq illustrate these weaknesses. The U.S. military went into the Iraq War with many technological advantages. These included data transmission capacity that was 42 times faster than what was available to U.S. forces during the Gulf War; a plethora of sensor technologies such as motion sensors, heat detectors, and reconnaissance eavesdroppers; and an advanced vehicle tracking system, Blue Force Tracker, which marks the location of U.S. units and enables e-mail communication. The technology available to the enemy forces pales in comparison. But despite these significant advantages in information gathering, the methods used by the military to communicate that information suffered from critical flaws. Information about enemy movements and troop levels did not reach the officers on the ground in many cases, despite the wealth of technology available. Why? First the technology itself was often less efficient than advertised. Units...

Standford Search Techniques in Path Planning

...We describe a practical path-planning algorithm that generates smooth paths for an autonomous vehicle operating in an unknown environment, where obstacles are detected online by the robot’s sensors. This work was motivated by and experimentally validated in the 2007 DARPA Urban Challenge, where robotic vehicles had to autonomously navigate parking lots. Our approach has two main steps. The first step uses a variant of the well-known A* search algorithm, applied to the 3D kinematic state space of the vehicle, but with a modified state-update rule that captures the continuous state of the vehicle in the discrete nodes of A* (thus guaranteeing kinematic feasibility of the path). The second step then improves the quality of the solution via numeric non-linear optimization, leading to a local (and frequently global) optimum. The path-planning algorithm described in this paper was used by the Stanford Racing Teams robot, Junior, in the Urban Challenge. Junior demonstrated flawless performance in complex general path-planning tasks such as navigating parking lots and executing U-turns on blocked roads, with typical fullcycle replaning times of 50–300ms. Figure 1: Junior, our entry in the DARPA Urban Challenge, was used in all experiments. Junior is equipped with several LIDAR and RADAR units, and a high-accuracy inertial measurement system....

Devices That Assist People with Disabilities

...Devices that Assist People with Disabilities Sheewane Davis Mercer University In the 2008 Census, over 10 million Americans reported a daily activity limitation and their activities of daily living (ADLs) usually required assistance from tools or caregivers. Moreover, about 0.3 million Americans have experienced a serious spinal cord injury (SCI), for whom essential tasks, such as dressing, preparing food, or taking medications, usually require the assistance from personal caregivers. However, the shortage and high cost of experienced caregivers fail rapidly growing needs for personal assistance. Technology which aids in these tasks is in great demand and it must allow the user to independently and safely control both mobility and manipulation in their home or the community. Robotics technology has been widely applied in rehabilitation technology and assistive devices to enhance the performance of assistance and quality of life of people with disabilities. By attaching a robotic manipulator to a mobile base, such as a wheelchair or a mobile robot, several robotic assistive devices have been developed to provide both mobility and manipulation assistance to people with severe physical impairments. However, most existing devices only provide a single-arm manipulation, which greatly reduce their efficiency of assistance and restricts their ability to perform complex manipulation tasks which require the involvements of both arms, for example, open the refrigerator with one......
