Human knee joint has a yaw-axis rotational DOF and a locking mechanism called screw-home mechanism. We focus on this mechanism and implement it to a musculoskeletal humanoid through hardware design. The importance of developing a knee joint with screw-home mechanism is that such a joint is capable of working yaw-axis properly and generating enough pitch joint torque for supporting whole body motion...
We have developed and studied musculoskeletal humanoids. Our goal is to realize a more human-like humanoid as a real human simulator, which has the same muscle and joint arrangements as human's and can do natural and dynamic motions as well as humans. Especially, it is very challenging to design musculoskeletal structure which can contain a large number of high powered muscles. Now, we design new...
In order to know human dynamics, humanoid as a human body simulator is increasing its importance. Such humanoid is expected to have human musculoskeletal structure as close as possible. From this viewpoint, we are trying to create new musculoskeletal humanoid which has detailed human imitating structure, such as bi-articular muscle, muscle arrangement, joint structure and so on. In this paper, we...
To design a robot with humanlike body structure, this paper presents a design methodology for a humanoid upper limb by tendon driven system. We newly designed an upper limb and rib cage like thorax for a musculoskeletal humanoid robot, based on the knowledge of anatomy. The robot consists of muscle, bone, and joint structure based on human and is expected to move flexibly and dynamically. This paper...
Our laboratory has tackled the composition theory approach of clarifying the structure in the human body by imitating it. Focusing on the hip joint, which has many complex muscle groups, we estimated and implemented 15 muscles to restrict the hip joint. However, it was difficult to implement such a quantity muscles to musculoskeletal humanoid because motor space is limited and the frame must have...
We are trying to create a novel musculoskeletal humanoid robot which has a humanlike structure. In this paper, we present a new knee joint which is usually simplified in robotics for high controllability. The knee joint has three human mimetic points, patella, screw-home mechanism and four-linked linkage. Patella is for a longer moment arm. Screw-home mechanism is for locking knee joint. Four-linked...
In recent years, humanlike robots have recieved a lot of attension. For making humanlike robots, a muscu-loskeletal humanoid is an effective approach. However, many musculoskeletal humanoids have not yet been equipped with really humanlike bones and muscles, especially for the body trunk, which is the core of the robot. For making a powerful and lithe humanoid body trunk with really humanlike bones...
