This paper presents the development of high-speed and high-power humanoid robot research platform JAXON. Researchers have studied humanoid robots widely and people expect humanoid robots to help various tasks such as housework, entertainment, and disaster-relief. Therefore it is important to develop humanoid research platform available in various fields. We considered the following as design requirements necessary to utilize humanoids for various uses. 1) Robots have humanlike body proportion to work in infrastructure matched to human body structure. 2) Robots have the same degree of physical performance as humans. 3) Robots have energy sources such as batteries and act without tethers. 4) Robots walk with two legs or four limbs and continue to work without fatal damage in unexpected rollover. JAXON satisfied these requirements. Then we demonstrates the performance of JAXON through the experiment of getting out of a vehicle, stepping over walls, squatting with heavy barbels, walking with four limbs, and operating on batteries. Further more, we assesses the performance of the strong armor and the shock absorbing structure through a backward over-turning accident.

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.
