  3. The BAE Systems Project: Design a way for military convoy humvee operations to detect obstacles in advance, offer a course of action for obstacle avoidance to the driver, and maintain spacing between members of the convoy. The design should be as cost effective, efficient, durable, and user friendly as possible, and it should be a product that can update the current fleet of military humvees without major modifications. The problem

  4. The MODS is a simple, cost-efficient, and effective system for obstacle detection and prevention, as well as a following distance indicator. The Design

  5. The MODS system detects obstacles using Ladar Uses a high frequency signal transmitted from one humvee to a receiver on the next to maintain spacing Features

  6. The MODS system can detect obstacles up to 1700 meters under perfect conditions, about half that under bad conditions. A simple readout gives the driver information about approaching obstacles This allows the driver to make the decision in real time about avoidance of an oncoming obstacle Features continued

  7. The MODS system is high tech, but it also allows for simple, direct, and decisive communication of the data and information it gathers to the user User interface

  8. With a second passenger in the car the Ladar can be used to create a complete 3D ground mapping Varying degrees of complexity

  9. A supersonic, adjustable frequency transmitter is attached to the back of each humvee, and a receiver is attached to the front This system produces a simple distance readout to help drivers maintain following distance Convoy spacing maintenance

  11. Speed of convoy = 50 km/hr = 13.89 m/s Maximum g-force human can withstand before being thrown from a vehicle = 1.3 g’s Acceleration (a) = 1.3 g’s = 1.3 * 9.8 = 12.74 m/s2 Radius (r) = v2/a r = (13.89) 2/12.74 r = 15.14 m Calculations

  12. Average reaction time = 0.215 s Distance traveled while reacting: d = vt d = 13.89 * 0.215 d = 3 m Radius as a function of velocity: R(v) = v2/12.74 Calculations cont.

  15. Contracted by the military • Detects image of terrain • Preprocesses the image in the sensor • Sends information to the input software • Information converted to real time and range • 3-D image displayed on laptop screen • Laptop installed with a Hyper-X chip • Increases speed and memory of processor Spec Ladar • Specs: • Range: 940 – 1180 m • Accuracy (while moving): 8 in. • Frequency: 850 nm • Input Power: 9 – 30 VDC

  16. Stainless steel encased sensor • rigid • withstand being underwater • Sends out an ultra-sonic beam • Beam bounces off of object in front of it and comes back • Sensor detects beam • Converts information to show distance between objects • Incorporates a SYNC feature • permits multiple sensors without “cross talk” ToughSonic Distance Sensor ("TS") • Specs: • Range: 25 cm – 9.1 m • Measure Rate: 50 mSec • Input Power: 10 – 30 VDC

  17. Sends out a laser beam at a slight angle towards the ground Laser bounces off of ground and comes back to receiver System computes distance Displays information on readout screen Any spike in distance, due to hole in ground, will result in an alert on the readout Once alert detected, a program will continually show the distance to the obstacle Universal laser sensor Specs: -Range: Up to 250m -Accuracy: +/- 1 cm -Power: 10 – 30 VDC

  21. Spec Ladar – 3rd Generation • max: $10,000 min: $5,000 • HyperX DDR3 Chip • max: $400 min: $313 • ToughSonic Waterproof (distance sensor) • max: $595 min: $495 • Universal Laser Sensor • max: $2,000 min: $1,700 Sensors

  22. INSTALLATION 8hrs (1day) per vehicle and 2 people working on each vehicle. 8hrs*2people*3vehicles= 48 paid hrs. TESTING 16hrs of testing and 2 people needed per vehicle. 16hrs*2people*3vehicles= 96 paid hrs. Labor
