Submarine with one motor and two axes of rotation


This robot is a submarine with one motor that drives rotation along two perpendicular axes and features a clever gear box that enables the transfer of energy along these two dimensions. It was built by kids (mostly orphans) at Anbarasi Social Action - a Miracle Foundation home in deep interior Southern India.  This was the result of a collaboration between Science in a Suitcase, Miracle Foundation, and 2 students - Rohit and Sidharth Srinivasan from Westlake High School and Hill Country Middle School, respectively, in Austin Texas. These kids were exposed to computers for the first time in October in a Science in a Suitcase camp . This robot was built at the end of a 2 day robotics camp taught by Rohit and Sidharth using curriculum provided by Science in a Suitcase on the 25th and 26th of December and applying robot design principles and content from Westlake's Robotics program (FRC Team 2468).

    Very cool, using a single motor to create motion along two axes! I wish we could see the gearing you used in the video–I’d love to see what you did.
