What a hassle• Everyone can agree one of the worst things
about talegating is carrying the cooler
• So what if you didn’t have to
Presenting the TaleGator
IDEA
• When this project is done nobody should ever have to carry a cooler again.
• The gator follows a specified colored shirt (orange or blue) colortracking program
• Incase of pedestrians getting in its way it avoids obstacles using ultrasonic sensors.
Sensors
• Ultrasonic sensor:– 1:mounted to the front left– 2:mounted to the front right– 3:mounted to the back center
• Camera– CmuCam mounted at an angle to the center front

Changes
• The original design called for four small motors each with a large wheel.
• This design couldn’t hold weight so it was replaced with a two drive wheel system and a caster in the back.
Current progress
• Body is fully put together with sensors mounted
• The programs to track colors and to avoid obstacles have been written
• Feedback is given in the form of two led lights mounted on the front of the body

Limits
• The robot seems to pick up things such as leaves as obstacles
• Seems to have difficulties with some colors depending on the light
• Has a weight limit for the cooler it can carry so cooler cannot be fully loaded.
