An Adaptive Three-Dimensional Nonlinear Path following Method for a Fix-Wing Micro Aerial VehicleInternational Journal of Advanced Robotic Systems - Tập 9 Số 5 - 2012
Cunxiao Miao, Jiancheng Fang
This paper describes an adaptive control approach of three-dimensional (3D) nonlinear path following for a fix-wing micro aerial vehicle (MAV) with wind disturbances in complicated terrain. We derive the control laws of course and flight path angle by the constructed Lyapunov function applying vector field theory based on the error equations in the Serret-Frenet frame, which are built by ...... hiện toàn bộ
Design and Control of a Powered Hip Exoskeleton for Walking AssistanceInternational Journal of Advanced Robotic Systems - Tập 12 Số 3 - 2015
Qingcong Wu, Xingsong Wang, Fengpo Du, Xiaobo Zhang
The wearable powered exoskeleton is a human-robot cooperation system that integrates the strength of a robot with human intelligence. This paper presents the research results into a powered hip exoskeleton (PH-EXOS) designed to provide locomotive assistance to individuals with walking impediments. The Bowden cable actuated exoskeleton has an anthropomorphic structure with six degrees of f...... hiện toàn bộ
Closed-Loop Behavior of an Autonomous Helicopter Equipped with a Robotic Arm for Aerial Manipulation TasksInternational Journal of Advanced Robotic Systems - Tập 10 Số 2 - 2013
Konstantin Kondak, Kai Krieger, Alin Albu‐Schäffer, Marc Schwarzbach, Maximilian Laiacker, Iván Maza, Ángel R. Castaño, Anı́bal Ollero
This paper is devoted to the control of aerial robots interacting physically with objects in the environment and with other aerial robots. The paper presents a controller for the particular case of a small-scaled autonomous helicopter equipped with a robotic arm for aerial manipulation. Two types of influences are imposed on the helicopter from a manipulator: coherent and non-coherent inf...... hiện toàn bộ
