  • My talk in the conference.

    I gave a talk on IEEE/RSJ International Conference on Intelligent Robots and Systems 2014. It's the world's top robotics conference.


    My talk is about trajectories optimization of flapping wings in insects flight. We explain how insect use flight muscles to tune wing kinematics, and propose a novel principle that allows for design simplifications of insect robots.

    • YQParse is another Parse iOS SDK totally based on REST API.
    • YQParse lets you interact Parse.com with a HTTP request, including saving objects and retrieving objects.
    • You probably need YQParse, only when you need to build your own static SDK which requires a backend. For the most time, you don't need to use it. Just downloading the official Parse iOS SDK works.
