This paper considers autonomous onboard hovering flight control of a micro quadrotor using a strapdown optical flow sensor which is conventionally used for desktop mice. The vehicle considered in this paper can carry only a few dozen grams of payload, therefore conventional camera-based optical flow methods are not applicable. We present autonomous hovering(More)
This paper presents planning and control of multiple aerial manipulators for cooperative transportation. Individual aerial manipulators which consist of a hexacopter and 2-DOF robotic arm are controlled by an augmented adaptive sliding mode controller based on a closed-chain robot dynamics. The desired path for each aerial manipulator is obtained by using(More)
This paper presents robust control for a quadrotor using TS (Takagi-Sugeno) fuzzy model and an LMI (Linear Matrix Inequality) approach. TS fuzzy model can provide an effective representation of nonlinear systems with a set of local linear models. We present TS fuzzy model for the quarotor which is composed of local linear models valid in different operation(More)
This paper presents vision-based lifting of a payload using two quadrotor UAVs. It is assumed that the exact position of a payload is not available. Specifically, for multiple UAVs to approach and connect the correct spots on the payload, image-based visual servo (IBVS) is adopted. A sliding mode controller is designed to track reference positions and(More)
This paper presents an estimation and control algorithm for an aerial manipulator using a hexacopter with a 2-DOF robotic arm. The unknown parameters of a payload are estimated by an on-line estimator based on parametrization of the aerial manipulator dynamics. With the estimated mass information and the augmented passivity-based controller, the aerial(More)
