Autonomous aerial perching and unperching using omnidirectional tiltrotor and switching controller
Dongjae Lee, Sunwoo Hwang, Jeonghyun Byun +2
Aerial unperching of multirotors has received little attention as opposed to perching that has been investigated to elongate operation time. This study presents a new aerial robot…
Minimally actuated tiltrotor for perching and normal force exertion
Dongjae Lee, Sunwoo Hwang, Changhyeon Kim +2
This study presents a new hardware design and control of a minimally actuated 5 control degrees of freedom (CDoF) quadrotor-based tiltrotor. The proposed tiltrotor possesses severa…
Design and Operation of Autonomous Wheelchair Towing Robot
Hyunwoo Kang, Jaeho Shin, Jaewook Shin +2
In this study, a new concept of a wheelchair-towing robot for the facile electrification of manual wheelchairs is introduced. The development of this concept includes the design of…
Design, Modeling and Control of a Top-loading Fully-Actuated Cargo Transportation Multirotor
Wooyong Park, Xiangyu Wu, Dongjae Lee +1
Existing multirotor-based cargo transportation does not maintain a constant cargo attitude due to underactuation; however, fragile payloads may require a consistent posture. The co…
