2014-2015 Infosession

UNIVERSITY OF TORONTOMECHATRONICS DESIGN

ASSOCIATION

WHO ARE WE?

• Design autonomous underwater vehicle/robotic submarine

• Compete at annual International RoboSub competition in San Diego

ROBOSUB COMPETITION?

• Underwater obstacle course in an anechoic sonar testing pool – TRANSDEC

• Hosted by AUVSI + RoboNation in San Diego

• Held in a military naval base

• Universities and engineering companies from all over the world

AUV DECOMMISSIONING

• Our Legacy AUV – AquaTux

AQUATUX SPECS AND KNOWN ISSUES

• Hull – hard to balance (ballasts)

• PVC-pipe frame

• 5 thrusters – 1 less degree of freedom

• Field Programmable Gate Array (FPGA)

• No automatic leak detection

• Netbook

TEAM BREAKDOWN
