The paper introduces the configuration of a multi-legged walking robot with hand-food-integrated mechanism arm. The obtained results demonstrate efficiently the validity of the proposed controller for guiding the walking robot when the disturbance is applied. An overall control policy can then be determined using model-based methods like Internal Model Control, or with machine learning techniques like reinforcement learning. Closed-loop motion controllers require information about the environment through sensors. Optimization tools are useful in many aspects of robot modeling and simulation, such as.
