A robot's head is important both for directional sensors and, in human-directed robotics, as the single most visible interaction interface. However, designing a robot's head faces contradicting requirements when integrating powerful sensing with social expression. Furher, reactions of the general public show that current head designs often cause negative user reactions and distract from the functional capabilities.Therefore, this contribution presents a novel anthropomorphic robot head called "Flobi", which combines state-of-the-art sensing functionality with an exterior that elicits a sympathetic emotional response. It can display primary and secondary emotions in a human-like way, to enable intuitive human-robotinteraction. To facilitate further research on facial appearance, the exterior is fully modular and replaceable.While current state-of-the-art still requires trade-offs when integrating sensing and social expression, Flobi has been designed to enable service robotic applications, with highresolution, wide-angle stereo vision, gyroscope motion compensation and stereo audio. For ease of integration, the head is selfcontained, including 18 actuators, sensors and control boards, all in a human-head sized package.

This paper presents the design, implementation and application of a humanoid interaction robot (H10). In interdisciplinary cooperation H10 was developed as a case study to operate at points of sale, information desks and demonstrations. If the user given speech input matches an entry of the adaptive database, H10 will react with a suitable answer. Synchronously to the speech generation, face animation and pre-defined gestures of hands and arms are triggered by the core of the system. The principles of the speech, gesture and physical interaction interface as well as some fundamental mechanic and electronic details are described.

Abstract-This paper presents the humanoid robot BARTHOC who has been developed to study human-robot interaction (HRI). The main focus of BARTHOC's design was to realize the expression and behavior of the robot to be as human-like as possible. This allows to apply the platform to manifold research and demonstration areas. With his human-like look and mimic possibilities he differs from other platforms like ASIMO or QRIO, and enables experiments even close to Mori's 'uncanny valley'. The paper describes details of the mechanical and electrical design of BARTHOC together with its PC control interface. Through its humanoid appearance, it can imitate human behavior with its soft-and hardware. Currently, several components for HRI on a mobile robot platform are being ported to BARTHOC. Starting with these components, the robot's human-like appearance will enable us to study embodied interaction and to explore theories of human intelligence.

This paper presents the humanoid robot BARTHOC and the smaller, but system-equal twin, BARTHOC Junior. Both robots have been developed to study human-robot interaction. The main focus of BARTHOC's design was to realize the expression and behavior of the robot to be as human-like as possible. This allows us to apply the platform to manifold research and demonstration areas. With its human-like look and mimic possibilities it differs from other platforms like ASIMO or QRIO and enables experiments even close to Mori's 'uncanny valley'. The paper describes details of the mechanical and electrical design of BARTHOC together with its PC control interface and an overview of the interaction architecture. Its humanoid appearance allows limited imitation of human behavior. The basic interaction software running on BARTHOC has been completely ported from a mobile robot except for some functionalities that could not be used due to hardware differences such as the lack of mobility. Based on these components, the robot's human-like appearance will enable us to study embodied interaction and to explore theories of human intelligence.

1. Introduction Recently, many studies have focused on the development of humanoid biped robot platforms. Some of the well-known humanoid robots are Honda's humanoid robots, the WABIAN series of robots from Waseda University, Partner, QRIO, H6 and H7, HRP and JOHNNIE. Given that humanoids are complex, expensive and unstable, designers face difficulties in constructing the mechanical body, integrating the hardware system, and realizing real-time motion and stability control based on human-like sensory feedback. Among the robots, HRP and ASIMO are the most well known humanoid robot platforms. HRP-3P is a humanoid robot developed jointly by the National Institute of Advanced Industrial Science and Technology and Kawada Industries, Inc in Japan. It stands 1.6 m tall, weighs 65 kg, and has 36 degrees of freedom (DOF). Upgraded from HRP-2, the new platform is protected against dust and water. In addition, Honda has unveiled a new type of ASIMO, termed the ASIMO Type-R, which stands 1.3 m tall, weighs 54 kg, and has 34 DOF. With the i-WALK technology, this robot has an impressive walking feature: it can walk at 2.7 km/h, and run at 6 km/h. HUBO is essentially an upgraded version of KHR-2. The objective of the development of HUBO was to develop a reliable and handsome humanoid platform that enables the implementation of various theories and algorithms such as dynamic walking, navigation, human interaction, and visual and image recognition. With the focus on developing a human-friendly robot that looks and moves like humans, one focus was on closely aligning the mechanical design with an artistic exterior design. This chapter also discusses the development of control hardware and the system integration of the HUBO platform. Numerous electrical components for controlling the robot have been developed and integrated into the robot. Servo controllers, sensors, and interface hardware in the robot have been explained. Electrical hardware, mechanical design, sensor technology and the walking algorithm are integrated in this robot for the realization of biped walking. This system integration technology is very important for the realization of this biped humanoid. The technologies utilized in HUBO are the basis of the development of other HUBO series robot such as Albert HUBO and HUBO FX-1. Albert HUBO is the only humanoid robot that has an android head and is able to walk with two legs. The face, which resembles Albert Einstein, can imitate human facial expressions such as surprise, disgust, laughter, anger, and sadness. The body, comprising the arms, hands, torso, and legs, is that of HUBO. The body of HUBO was modified to have the natural appearance despite the disproportionate sizes of the head and the body. It can be described as Albert Einstein in a space suit. The realization of a biped walking robot with an android head is a first-in-the-world achievement. The design and system integration between the head and the body are discussed. RC motors are used for the head mechanism, enabling facial expressions. The head and bod...
