CajunBot Innovation:Simulator
Complete virtual world for testing software Significant challenge
Running ‘real-time’ systems in virtual environment Solution:
A virtual-clock Encapsulate clock into an object
Team Composition
Graduates of Rayne High Berwick High Baton Rouge High Catholic High, New Iberia Slidell High Kenner High Lafayette High Carencro Comeaux India, Nigeria, China, Tunisia
DARPA Grand Challenge 2007
Autonomous Vehicles in traffic Model vehicles in cities
New issues Detect other vehicles on road Follow road rules (right of ways)
Challenge date To be announced Most likely in August 2007
Pikes Peak Uphill Robot Race
Colorado Springs Course for autoracing Second only to Indy-
500, but uphill Stats
Length: 12.42 miles Turns: 156 Start elevation: 9,390ft End elevation: 14,110ft Grade: +/- 10%
Buckeye Invitational
Led by Ohio State At Transportation
Research Center’s Cross Country Hilly Course
Over 8 miles of roadway, 1000ft/105 slop, cross-country course, etc.
3-D Survey
Differentiating from aerial survey Single point per cell vs multiple points per cell Higher resolution Higher accuracy
Thanks to C&C’s RTK equipment Application
3-D models of levee, coastal region, bridges, structures
Review damages to structures Post construction review of roads, bridges
3-D Games and Animations
Costly part of computer games Creation of models
Use CajunBot technology to create 3-D models Scan objects Extract 3-D points Construct model Skin images
DOD: Robotic Systems
Single autonomous system not sufficient DOD expects collection of autonomous
robots
Robotic Systems: Bottleneck
Critical path technology Software Human computer interface Training of personnel
Testing requires Need fully equipped, functioning vehicles Trained personnel Testing area
Our proposal: Move testing and training to virtual world
Invitation for collaboration Mechanical Engineers; Art and Design
Improve mechanical structures Kinodynamic models of the vehicle
Electrical Engineers Scanning sensors Improve power management
Civil Engineers Use data to build models of roads, terrain, building, etc.
Chemical Engineers Chemical sensors – for spills, etc.
Computer science/engineering All aspects
Visualization, computer games, signal processing, AI
