Building a high-end aerial robot for research is a challenging task. Our aim in this paper is to design a compact hexacopter capable of high payload and has flexible gimbal and powerful onboard computer with $ 500. This hexacopter serves as a flying platform with great customizability, where different sensors can be mounted easily onto the hexacopter for new applications. We discuss our implementation...
Over the last decade, face alignment researches have been advancing rapidly and have vast applications related to face recognition, pose estimation, and human-robot interaction. Face alignment is typically performed in a two-stage fashion by alternatively using local landmark detector and global shape regularizer. While both landmark detector and shape regularizer have achieved impressive progress...
Most literatures have been relying on image processing approaches such as skin detection and depth thresholding for hand detection. These techniques are restricted by strong assumptions and normally possess low robustness in actual applications. In this paper, we focus on an appearance approach and propose a new feature extraction method based on sparse pixel-pair wise intensity comparisons for hand...
Facial expression recognition (FER) is important for robots and computers to achieve natural interaction with human. Over the years, researchers have proposed different feature descriptors, implemented different classification methods, and carried out test experiments on different datasets in realizing an automatic FER system. While achieving good performance, the most efficient feature space and...
Aerial robots offer a novel HRI platform thanks to their flying capabilities. However, existing aerial robots are designed from functional point of view and do not take social factors such as noise and appearance issues into serious consideration. Compared to quadrotor (noisier but higher speed), we investigated whether blimp (quieter but slower speed) is a better platform for social aerial robot...
This paper gives insight into the system design and hardware architecture of Nancy, which is a social robot in humanoid form that is currently being developed in Social Robotics Lab (SRL), Interactive and Digital Media Institute, National University of Singapore. In contrast to industrial robots, the design of Nancy focuses on safety issue, social interaction and attractive appearance. In order to...
This paper presents a social interactive robot Nancy that has been developed in Social Robotics Laboratory, National University of Singapore. Fundamentally different from factory robots, Nancy's design focuses on social interaction and social intelligent system. The design objectives and consideration are examined in the beginning, followed by the description of hardware and software architectures...
