Construction of Musculoskeletal Simulation for Shoulder Complex with Ligaments and Its Validation via Model Predictive Control

Yuta Sahara, Akihiro Miki, Yoshimoto Ribayashi, Shunnosuke Yoshimura, Kento Kawaharazuka, Kei Okada +1
IROS 2024poster

The complex ways in which humans utilize their bodies in sports and martial arts are remarkable, and human motion analysis is one of the most effective tools for robot body design and control. On the other hand, motion analysis is not easy, and it is difficult to measure complex body motions in deta…

Imitation Behavior of the Outer Edge of the Foot by Humanoids Using a Simplified Contact State Representation

Yoshimoto Ribayashi, Kento Kawaharazuka, Yasunori Toshimitsu, Daiki Kusuyama, Akihiro Miki, Koki Shinjo +5
IROS 2022poster

There is a way to utilize humanoid robots to mimic human behavior by taking advantage of their human-like proportions. In general, motion capture is used; in this case, the posture of the body links can be taken. However, this method does not provide detailed information on the contact state, which…

Learning of Balance Controller Considering Changes in Body State for Musculoskeletal Humanoids

Kento Kawaharazuka, Yoshimoto Ribayashi, Akihiro Miki, Yasunori Toshimitsu, Temma Suzuki, Kei Okada +1
IROS 2022poster

The musculoskeletal humanoid is difficult to modelize due to the flexibility and redundancy of its body, whose state can change over time, and so balance control of its legs is challenging. There are some cases where ordinary PID controls may cause instability. In this study, to solve these problems…

RAMIEL: A Parallel-Wire Driven Monopedal Robot for High and Continuous Jumping

Temma Suzuki, Yasunori Toshimitsu, Yuya Nagamatsu, Kento Kawaharazuka, Akihiro Miki, Yoshimoto Ribayashi +5
IROS 2022poster

Legged robots with high locomotive performance have been extensively studied, and various leg structures have been proposed. Especially, a leg structure that can achieve both continuous and high jumps is advantageous for moving around in a three-dimensional environment. In this study, we propose a p…
