Controlling a biped robot with several degrees of freedom is a challenging task that takes the attention of several researchers in the fields of biology, physics, electronics, computer science and mechanics. For a humanoid robot to perform in complex environments, fast, stable and adaptable behaviors are required. Developing robust behaviors requires the development of methods for joint trajectory planning and lowlevel control. Several methods are part of the state of the art, including…

CPG Implementations for Robot Locomotion: Analysis and Design
TLDR
Animal locomotion requires multi-dimensional coordinated rhythmic patterns that need to be correctly tuned so as to satisfy multiple constraints: the capacity to generate forward motion, with low energy, without falling over, while adapting to possibly complex terrain, and while allowing the modulation of speed and direction.
Motion Segmentation and Balancing for a Biped Robot's Imitation Learning
TLDR
An imitating algorithm called posture-based imitation with balance learning (Post-BL) is proposed, which allows demonstrated motions to be imitated balance to be preserved and uses a reinforcement learning mechanism, which is sufficient to stabilize the robot during online imitation.
Stability margin for robust walking gaits constructed by center of pressure
TLDR
A stability margin constructed by center of pressure (COP) to evaluate the gait stability of humanoid walking is proposed and the walking gaits developed based on stable COP region can be applied for different movement objectives.
Static stable regions acording to Center Of Press to quantify humanoid walking stability
Usually a walking pattern can be only roughly distinguished into stable or unstable. The evaluation of a humanoid walking stability is difficult to quantify. In this paper, static stable regions
Posture imitation and balance learning for humanoid robots
In robotics, controlling the robot by imitating human posture is going to be a tendency. To accomplish the objective of the posture imitation via the robot, there are two main points: extracting

The ability to efficiently move in a complex environment is a key property of animals. It is central to their survival, i.e. to avoid predators, to look for food, and to find mates for reproduction

TLDR
The model's prediction that control of the forward progression of the center of mass influences the nonlinear gait dynamics is supported, although these conclusions need to be further explored at a range of walking speeds.

TLDR
The foot-rotation indicator (FRI) point is introduced, which is a point on the foot/ground-contact surface where the net ground-reaction force would have to act to keep the foot stationary to ensure no foot rotation.
