One of the fundamental properties of pedestrian simulation models is their capability to predict the future movement dynamics of pedestrians depending on the current state of the pedestrian traffic flow, more specifically the walking behaviour of neighbouring pedestrians. This paper investigates the influence of the interaction characteristics on the strength of the reaction of pedestrians walk...

BACKGROUND In promoting physical activity, it is important to gain insight into environmental factors that facilitate or hinder physical activity and factors that may influence this environment-behavior relationship. As the personality factor of action orientation reflects an individual's capacity to regulate behavior it may act as a moderator in the environment-behavior relationship. The curre...

This paper proposes a new method to analyze human walking by using a 3-wheels rollator walker instrumented with encoders and a 3D accelerometer/gyrometer. In order to develop walking quality index and monitor the health state of elderly people at home, the walking of 23 young adults and 25 elderly people (> 69 years) with the help of the walker, are compared. The results show that many general ...

Many different and high-quality humanoid motions have been developed based on a tailored, 55cm tall humanoid robot kinematics and design using 21 servo motors and inertial sensors for stabilization. These include fast forward walking of about 1.5 km/h in permanent operation, multidirectional walking capabilities, a variety of standard and spectacular kicks, standing up motions as well as motion...

In this project, I aim to design and experiment with a controller for quadruped walking gait in a physics based simulation. A simplified and articulated dog model was designed with realistic dimensions. The controller is based on a finite state machine, where each state represents a target pose in the gait cycle. A simple balancing strategy was implemented.

this paper proposes a gait planning approach to reduce the required friction for a biped robot walking on various surfaces. to this end, a humanoid robot with 18 dof is considered to develop a dynamics model for studying various 3d manoeuvres. then, feasible trajectories are developed to alleviate the fluctuations on the upper body to resemble human-like walking. in order to generate feasible w...

To overcome the obstructions imposed by high-dimensional bipedal models, we embed a stable walking motion in an attractive low-dimensional surface of the system’s state space. The process begins with trajectory optimization to design an open-loop periodic walking motion of the high-dimensional model and then adding to this solution, a carefully selected set of additional open-loop trajectories ...

In this paper, we study languages of birooted trees or, following Scheiblich-Munn’s theorem, subsets of free inverse monoids. Extending the classical notion of rational languages with a projection operator that maps every set of birooted trees to the subset of its idempotent elements it is first shown that the hierarchy induced by the nesting depth of that projection operator simply correspond ...
