January 24 rd, 2013 Additional Concepts and Communication

Overview Concepts from Kumoh and Budapest Flexible/expandable wheel concepts Communication with International Teams SPECIFICATIONS – For current version of specifications sheet, see Google Document

Concepts from Kumoh and Budapest

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)

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?

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?
