4 Previous Design History Culture Shock I 2009 Culture Shock II 2010 Vulture I 2011

5 Previous Design History Performance – Low center of gravity – High Power 24V motors – Low moment of inertia – High-performance computer systems – Cambered wheel design – Dual Chain tensioners Safety Gel Batteries Reliable E-stop Audible & Visible alerts Speed-limiting via Motor Controller

6 Previous Design History Reliability & Maintainability – Durable materials – Modular construction – Passive sensors Small footprint – Increased maneuverability – Ease of testing

7 New Platform Design Process Reduced Camber angle to 7 Revised Suspension for more durability Built Sensor Test Cart for sensor development 12VDC Monitor eliminates inverter Continuous design improvement

8 New Platform Design Process Built Sensor Test Cart for sensor development

9 Stereo Vision System Low cost web cameras. Open source stereo vision software (Emgu, C# wrapper for OpenCV)

10 Disparity, Rectified, and Obstacle Images Disparity Image Obstacle Image Left Camera Rectified Image
