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 November 2007

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

Lessons Learned

Lesson 1: Its all in the attitude
Louisiana attitude Self-flogging Focus on all that is wrong Not appreciate what you have Aim low, so you will not fail
CajunBot attitude Impossible is nothing Others earned their keep; we got to earn ours Take your licks; and keep going for more
![Page 25: CajunBot: Lessons](https://reader035.fdocuments.in/reader035/viewer/2022062720/5681351a550346895d9c6f0f/html5/thumbnails/25.jpg)

Lesson 2: Choose ‘Area’ wisely
Choice of area defines growth potential Spent 10 years in ‘reverse engineering’ Very difficult to attract students, collaborators,
funds, media excitement Entered Robotics three years ago
Several hundred thousand dollars from university Over forty students ‘touched’ directly Five collaborators Several sponsors Media overdose
![Page 27: CajunBot: Lessons](https://reader035.fdocuments.in/reader035/viewer/2022062720/5681351a550346895d9c6f0f/html5/thumbnails/27.jpg)
Lesson 3: Don’t box yourself
People identify themselves by their degrees and training: Computer Scientist working on tools to reverse
engineer legacy systems Identity defines what you do
and also What you do not do Most people are multifaceted Degrees should not limit what you can do
![Page 28: CajunBot: Lessons](https://reader035.fdocuments.in/reader035/viewer/2022062720/5681351a550346895d9c6f0f/html5/thumbnails/28.jpg)

Lesson 4: Aim high, people will follow Reasons for not aiming high
No support from community, family Resources needed do not exist
CajunBot lesson No dearth of resources in community People love to support risk takers
Majors of Melville – gave ATV on a phone call Chance of C&C – gave equipment worth several $100K Lafayette Motors – new Jeep Firefly – Web support Pixus – Decals Honda of Lafayette – Generator “2 the max ATV” – a full new ATV to use for spare parts

Angels in the Desert
Gave new ATV to use
as spare parts bin

Lesson 5: Do not underestimate your local talents
Attitude in Louisiana Consider ourselves
second Limit ourselves on what
we can do
CajunBot experience shows Plenty of talents around Not enough opportunities
to challenge the talent
2005 Team CajunBot Berwick High Baton Rouge High Catholic High, New Iberia Slidell High Kenner High Lafayette High Carencro Comeaux India, Nigeria, China

Lesson 6: Buy, don’t build
Common attitude I can build it myself Will save money
CajunBot experience Started with buying inexpensive equipment Spent time in chasing wrong problems Finally bought the more expensive equipment People, even students, are not free 2007 GC
Acquired the best sensors

Lesson 7: Team fails, not individuals
Common attitude Pin fault to an individual
CajunBot experience Failures result from succession of poor judgment Team succeeds together; team fails together
![Page 34: CajunBot: Lessons](https://reader035.fdocuments.in/reader035/viewer/2022062720/5681351a550346895d9c6f0f/html5/thumbnails/34.jpg)
Lesson 8: Choose competitors
Common wisdom: You are defined by the company you keep
CajunBot experience: You are defined by your competitors
![Page 35: CajunBot: Lessons](https://reader035.fdocuments.in/reader035/viewer/2022062720/5681351a550346895d9c6f0f/html5/thumbnails/35.jpg)

Lesson 9: Don’t underestimate your competitors
Common attitude Gauge competition by their past performance
CajunBot experience Team Gray of Gray Insurance Company
outperformed us (and everyone else)
![Page 37: CajunBot: Lessons](https://reader035.fdocuments.in/reader035/viewer/2022062720/5681351a550346895d9c6f0f/html5/thumbnails/37.jpg)
Insurance company beat us

Lesson 10: Have fun
Don’t take yourself too seriously Excitement of challenge also wears off
