Wouldn't it be crazy to fly a small drone or helicopter with your phone or tablet running nothing but a web browser? This session will tell you all about it! Imagine a fully functional touch based user interface for remote controlling a small drone or a helicopter. This is doable with latest experimental integrations around drone controlling backend applications over WIFI with touch based control interface built with GWT or Vaadin. During the session such a system will be presented with full technology stack starting from GWT based frontend to the actual backend controller application. A live drone will also be flown during the talk maintaining a safe distance from the audience.
