5. 내 용 :
Not being grounded like most other conventional robotic systems (e.g., wheeled robots), quadrotor robots are promising to truly expand the current robots’ capability to 3D environments.Some applications include: aerial surveillance and reconnaissance, remote aerial movie shooting, evaluation and repair of infrastructure, and operation on a high-rise building, to name just few.

In this talk, I will introduce some recent results in my lab for the control of this quadrotor robot, with an aim toward (teleoperated or autonomous) aerial manipulation using the (single or multiple cooperative) quadrotors, which has much less studied as compared to the quadrotor’ motion control problem, albeit it being an indispensable capability for many practical robotic operations.In particular, the following control problems will be discussed: 1) trajectory tracking control of the quadrotor robot using backstepping in SE(3); 2) semi-autonomous teleoperation of multiple quadrotors with distributed cohesion/avoidance actions; 3) distributed formation control of multiple quadrotors on a balanced information graph; and 4) dynamics and control of some simple tool operations by a single quadrotor robot.
Some other research activities in my lab will also be briefly introduced if time permits.
