Analyzing time-series changes of the contact surface by touching is important to elucidate the touching skills of Humanitude as one of the pervasive multimodal comprehensive care methodologies. However, the transparent flat plates to capture contact surfaces used in the previous studies are far from the actual surfaces of care receivers because the surfaces of humans consist of curved shapes. In this paper, we propose a Frustrated Total Internal Reflection (FTIR) sensing system using a transparent curved plate for the purpose to capture contacting state by using a surface more similar to the human body. We evaluate the equivalent performance between data from the proposed FTIR sensing system and an FTIR sensing system using a transparent flat plate by calculating time-series contact areas and the quantitative indices representing theHumanitude's touching motion. Through these experiments, we conclude that the proposed system can obtain the same data quality for the contact areas and the indices as the FTIR system using the flat plate.

In this paper, a new wheel mechanism for holonomic and omnidirectional mobile robots is presented. The caster drive technique is one of the feasible solutions to allow a vehicle to have holonomic and omnidirectional mobile capability with standard wheels. The caster drive is applied to a differential drive mechanism. A drive unit equips with two drive wheels driven by individual motors. The rotational stage, driven by the third motor, is mounted on the drive unit with its rotational center locating at the off centered position from the mid point of the two driving wheels. The translational position and velocity of a mobile base are controlled by the differential-drive mechanism executing a caster like behavior. The orientation of the mobile base is controlled by the rotational stage decoupled with the translational motion of the drive unit. The vehicle 3DOF are controlled by the three motors, hence the system includes no over constraint problem. In addition, the drive mechanism is very simple and could be implemented by using a traditional differential-drive mechanism.

The development of cybernetic human HRP-4C is presented in this paper. The word “Cybernetic Human” is a coinage for us to explain a humanoid robot with a realistic head and a realistic figure of a human being. HRP-4C stands for Humanoid Robotics Platform-4 (Cybernetic human). Standing 158[cm] tall and weighing 43[kg] (including batteries), with the joints and dimensions set to average values for young Japanese females, HRP-4C looks very human-like. This paper introduces the project overview, the design process, mechanical features, and electrical features with specifications of HRP-4C.

This paper presents balance control analysis of humanoid robot based on Zero Moment Point (ZMP) feedback control. The ZMP is often used as a standard evaluation of the stability of humanoid robot. Balance control is performed by controlling ZMP position so that it is always located in convex hull of the foot-support area. To simplify the design of controller, one-mass model which represents lower body part of the humanoid robot model has been commonly applied. However, the one-mass model causes the system becomes non-minimum phase, so that performance limitation is occurred. These disadvantages are attributed to the Waterbed effect in frequency domain and unavoidable undershoot in time domain. Therefore, this paper proposes the ZMP feedback control based on two-mass model, representing lower and upper body part of the humanoid robot. The proposed model results in minimum phase system. Finally, a design of controller based on the proposed model using Linear Quadratic Optimal Control by evaluating output of the system is described and confirmed using simulation.

Participation in collaborative projects is regarded to be one of the necessary activities for universities and colleges. Furthermore, participation of students in such projects is expected to be effective from the view of an engineering design education and social implementation education. Collaborative projects are usually carried out by several stakeholders, and they are required to be managed properly based on their interests. However, they tend to be managed by trial and error, because each stakeholder has different circumstances and different purposes. In this paper, stakeholder analysis was introduced and applied to two social implementation education projects that were carried out in the author's college. One is a management of a lecture where a speaker was invited from another college, and the other is a management of developing a mascot robot for a regional festival. The results from the stakeholder analysis and the author's cognition were compared. As a result, it was confirmed that the stakeholder analysis has a potential capability of a management of projects of social implementation education.

In the past decade, search type rescue robots have been focused on. Most robots took “linked mobile track” type such as snakes, so as to obtain high quality against unknown irregular surfaces. However the linked mobile track has some joints and sometimes they shut in some debris and stuck on it. In addition, many links increase total weight of robots and control complexity. In the paper, we propose a new type mobile mechanism, Flexible Mono-Tread Mobile Track (FMT) and develop a prototype called “Rescue mobile Track No.2 (RT02) WORMY”. The prototype consists of a flexible chain and a vertebrae like structure. Moreover, we investigate its performance against the irregular surfaces.

A self-contained type hexapod walking robot was developed in Mechanical Engineering Laboratory. It is called MELCRAB-2. This hexapod has specific features both in the mechanical design and in the control way. This paper provides a few significant guideline to design the self-contained hexapod walking robot from the point of view about the stair climbability, turning mobility, efficient foot force delivering based on the two decoupled actuation ways, GDA (Gravitationally Decoupled Actuation) and MDA (Motion Decoupled Actuation) . An approximately straight line linkage is used in the leg mechanism of the MELCRAB-2 to satisfy both of GDA and MDA. The inverse kinematics of the approximately straight line linkage was solved for position control. Tactile sensors and proximity sensors are installed on the front side and back side of each foot to detect obstacles and walking environments. Control algorithm with many motion procedures to negotiate the stairs and walking environments was developed. MELCRAB-2 could climb up the experimental stairs with the same dimensions as the real buildings by using that algorithm. MELCRAB-2 is the real self-contained hexapod robot actuated by electric motors, and it can walk with the fast speed owing to GAD and MDA. compared with the past developed walking machines.

Human knee joint has a yaw-axis rotational DOF and a locking mechanism called screw-home mechanism(SHM). We focus on this mechanism and implement it to a musculoskeletal humanoid through hardware design. In this paper, we first explained human knee characteristic of SHM and joint range of motion. Next, we explained hardware design and implementation method of the mechanism. As an evaluation of our developed knee joint, we checked the function of SHM from viewpoint of moment arm of the yaw rotational axis and the yaw angle displacement during squat motion. Lastly, as unique and integrated motions that involve the use of yaw DOF derived from SHM, we made several motion achievement including humanlike twisting squat, heel move motion and switch pedals, under a condition of contacting environment. This result demonstrates human mimetic rotational DOF of knee contributes motion achievement.

We develop a cyclogyro-based flying robot with a new variable attack angle mechanism. Cyclogyro is a flying machine which is supported in the air by power-driven rotors, which rotate about a horizontal axis, like the paddlewheels of a steamboat. Machines of this type have been designed by some companies, but there is no record of any successful flights. The proposed new variable attack angle mechanism has an eccentric point that is different from a rotational point. The main feature of the mechanism is to be able to change attack of angles according to the rotational angles of the cyclogyro without actuators. The lift and drag forces of the robot are calculated and measured through simulations and experiments. The simulation and experimental results show that the new mechanism generates positive lift forces at any rotational angles of the cyclogyro.

To extend the paralyzed fingers of a stroke victim with hemiplegia, we have proposed a low-dimensional control system for a robotic finger which can grasp an object between the robotic finger and the paralyzed human fingers. In this study, we newly propose an extra finger that can face multiple fingers with low-dimensional control. This can be realized by adding a rotational joint for moving the base of the robotic finger where it is controlled by the common low-dimensional synergy controller. Experimental results showed that the proposed extra finger could realize 33 grasping postures and 4 peg manipulation patterns.
