Additional Conceptsand Communication January 24rd, 2013
Overview • Concepts from Kumoh and Budapest • Flexible/expandable wheel concepts • Communication with International Teams • SPECIFICATIONS • For current version of specifications sheet, see Google Document
Quadrotor with Solar Charger • Solar cell in center of quadrotor (enough current to power microprocessor?) • Arms fold up to protect during landing
Rolling Concept • Motor powers inner ball, which rolls on inside of outer ball
Guiding Principles #1 • In order to avoid double effort on control design: we should navigate on the ground or in the air but not both • If we want to navigate in the air, wings are better than helicopter (rotor/propellers providing downward thrust) concept from the viewpoint of energy efficiency
Guiding Principles #2 • To avoid getting blown away by wind, the parachute should be opened late in the descent • If we make a flying robot, it should be naturally stable – flying robots can be very difficult to control if they are too reliant on fast/accurate feedback of pose (attitude)

Time Differences (Relative to Atlanta) • Budapest, Hungary: • Patras, Greece: • Madras, India: • Gumi City, South Korea: + 6 hours + 7 hours + 11 hours + 14 hours
Communication • RescueBot website • Online meeting software • Weekly meeting (Skype? Phone? Other?) • Assuming one country at a time • Split each team of Tech students into two groups?
File Sharing • RescueBot Website • Dropbox account • Google account (use Drive)
International Kickoff Meeting • Describe RescueBot project in detail • Find out interests/abilities • How to split specialized teams? • All EE (for example) from same country, or • Students from multiple countries? • How to split robot production? • Two groups, each working on one design, or • Farm-out tasks from both designs to specialties?
