Intelligent Ground Vehicle Competition

Intelligent Ground
Vehicle Competition
LTU Senior Project
Presenting to the Kern
Foundation
October 21st
What is the Intelligent Ground
Vehicle Competition about?
University project teams
 Unmanned, unguided, independently
acting robotic ground vehicles
 Navigation and obstacle avoidance
 Competition held at Selfridge Air Force
Base

IGVC Team 2006
Why does the Department of
Defense host IGVC?



The Department of Defense stated before
Congress that they would have 1/3 of their ground
vehicles made autonomous by 2015
However, no such vehicles have yet been made
DoD sponsors IGVC to encourage college
students to develop the field of unmanned ground
vehicles.

“The IGVC offers a design experience that is at
the very cutting edge of engineering education.
It is multidisciplinary, theory-based, hands-on, team
implemented, outcome assessed, and based on
product realization. It encompasses the very latest
technologies impacting industrial development and
taps subjects of high interest to students.”

Winning the IGVC


“A fully autonomous unmanned ground robotic vehicle
must negotiate around an outdoor obstacle course under
a prescribed time while staying within the 5 mph speed
limit, and avoiding obstacles on the track.”
Ranking based on:




+ Time taken
+ Distance traveled
-- Penalties
Penalties incurred by:



Obstacle collisions
Pothole hits
Boundary crossings

IGVC Team 2006
New Plan for the 2006 Competition

Build a new robot
 As
few parts as possible will be reused from the Think
Tank

Improve the software and hardware
 Advanced
algorithms for better object avoidance
 Vastly improved electrical and mechanical systems
 Built to JAUS Specifications

Involve engineering students to actualize
hardware solutions

Fuel Cell Concept







1.2 KW DC output – Useable Indoors and Outdoors
Safe and Environmentally Friendly
Weighs ~ 30-50 lbs
~ 2.5 by 1.5 ft
$7,000 cost
A single $200 dollar tank could last 6 days of continuous
use at 100% load
Recommended DC-DC converter to smooth output and
prevent excess power draw from motors
