Jonathan Rogers and his team are working on a funded project with the Georgia Tech Research Institute (GTRI) to test multiple vertical lift robots that connect up to deliver supplies. The robots are programed to take into account flexible logistics by connecting to the object (payload) and determining its weight and size and how to move it in a stable way. The small robots work together as a team, known as multi agent control.
