GS1140-Assignment 1: DARPA Challenge

How would you define this problem? What are the major problem components, and what obstacles do you for see?

* Terrain/weather conditions (Unexpected bumps / road damage, majority of which is out of our control, but we will work around them by equipping the vehicle properly) * Vehicle (Making sure the vehicle has proper gear and can withstand terrain/weather conditions) * Route (Tunnel shutting out equipment for navigation, turns, off course)

How fast do you need to go to complete the course in the allotted time?
It takes 17.5 mph to finish 175 miles in 10 hours but considering the obstacles, turns, and weather/terrain conditions we can boost it to 19 mph giving us an estimated finish time of 9:12:37 What is the fallacy of considering the above average speed- what you need to consider?

* Turns from mountain passes will cause the vehicle to slow down * Weather conditions such as rain, dust storms and heat could cause the vehicle to wither and slow down * Road hazards / obstacles such as holes in the ground causing vehicle to get stuck, rocks that may block the vehicle

What strategies can you use to avoid obstacles?

* Scanner systems (RADAR, LIDAR, GPS) for tracking, routing and incoming obstacle detection * 4 wheel drive letting the car maneuver faster and run smoother off road * Vehicle suspension with added aerodynamic side skirts/ from heavy wind to reduce drag and wind noise, Will also help to produce down force to improve traction and cornering abilities for turns

What are some disadvantages of the route information you receive, in terms of the vehicle driving the route?

* Road hazards(obstacles/potholes) * Tunnel will cause a possibility of GPS failure causing vehicle to get lost * Weather strain on vehicle such as heat causing engine failure, dust storms causing sensor malfunction, this causing vehicle to go off course

What strategies can you use to prepare your vehicle for the route once you receive the information?

* Off-road gear (tires, anti-weather) off-road tires will make a great traction for the dirt road and even muddy roads in case it rains, Anti-weather amour will protect the vehicle from rain and dust storms * Suspension, fairly off the ground to avoid us from slowing down if vehicle was to hit rougher terrain * Scanner systems (RADAR, LIDAR, and GPS) these scanners are the bread and butter of an autonomous vehicle. RADAR for obstacle detection, LIDAR for terrain/ geographical mapping, and GPS for routing

MTBCF stands for mean time between catastrophic failures. What kind of failures do you anticipate in the testing phase?

* Off course, if GPS is not routed properly or the tunnel will completely shut us out * Vehicle breaking/slowing down from dust storms slowing the vehicle, overheating from the sun * Weather conditions, making sure the vehicle can withstand it

...Favian Morales 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....

...Shannon Califf GS1140 Problem Solving DARPA Challenge 1. The problem is that you have to build a vehicle that can travel through the desert in less than 10 hours. One major problem is that you have a very short period of time to build something that you don’t even know will work. Another major problem that we can foresee is that we have no idea what this course looks like at all 2. The speed at which you would have to travel to complete the course in ten hours would be 17.5 mph 3. The fallacy is that you will probably not run this course all the way through without stopping. There are many reasons why are vehicle could stop like mechanical reasons or terrain reasons or are vehicle could even go the wrong way. 4. One major strategy we could use to avoid obstacles is install a camera on the vehicle so we know where it’s navigating as its driving. We could also install lights on the car for areas that are dark. The third thing we could do is to make sure we do our best at figuring out the path our vehicle will be taking. 5. Some disadvantages are that we don’t know if the GPS points are equidistant or how far apart they are. We also don’t know where on the path these points are or if they are in the center or off in a ditch somewhere. We also don’t know if the points are making up a curve or something else. 6. Some strategies we could use is to try and map everything out, make sure we know exactly which path our vehicle is......
