“…To improve the balance of a humanoid robot, different approaches have been explored in various working groups. These approaches include railings (Harada et al., ), trekking sticks (Khatib & Chung, ), or canes (Kobayashi, Aoyama, Sobajima, Sekiyama, & Fukuda, ). In contrast to other studies (Kajita et al., ), the arms of the robot cannot be used to compensate for the moments of inertia of the feet, since they do not have enough weight for that purpose.…”

Current and future application scenarios for mobile robots deal with increased requirements regarding autonomy and flexibility in the locomotor system. To cope with these demands, a high sensor quantity and quality allows us to perform robust locomotion. The authors present a hominid robotic system that is equipped with multi‐point‐contact feet and an active artificial spine to incorporate extended sensing and locomotion capabilities for walking robots. In the proposed robotic system, the front and rear part are connected via an actuated spinal structure with six degrees of freedom. To increase the robustness of the system's locomotion in terms of traction and stability, a footlike structure equipped with various sensors has been developed. Altogether, the robot embodies more than 330 sensors. In terms of distributed local control, the structures feature their own local intelligence and are as autonomous as possible regarding sensing, sensor preprocessing, control, and communication. This allows the robot to respond to external disturbances with minor latency. Within this paper, the proposed robotic system and its distributed and hierarchical control method are presented. To validate the electromechanical and software approach, the authors present results verified experimentally in different environments (in‐ and outdoor) with differing walking speeds on various substrates and in varying inclinations from −20∘ to 20°. The results show that the presented approach is viable and improves the flexibility of the locomotor system. A hominid design was chosen in order to perform various types of locomotion. To demonstrate the entire functionality of the developed hardware, two different motion modes (quadrupedal and bipedal locomotion) are investigated. This also includes a stable transition from a four‐legged posture to an upright posture and vice versa.
