Walking on irregular surfaces and in the presence of unexpected events is a challenging problem for bipedal machines. Up to date, their ability to cope with gait disturbances is far less successful than humans': Neither ...

Purpose: This study aimed to examine the associations of the perceived neighborhood built environment with walking and cycling for transport in inhabitants from Latin American countries. Methods: This cross-sectional ...

Developing a correct model for a biped robot locomotion is extremely challenging due to its inherently unstable structure because of the passive joint located at the unilateral foot-ground contact and varying configurations ...

The practice of physical activity brings several benefits for all age groups, but for the elderly population it is essential, since it favors the maintenance of independence, health, quality of life, among others. Among ...

This thesis presents a solution to the biped locomotion problem. The robot used for the experiments is robot Nao by Aldebaran Robotics and it is simulated in Webots mobile robot simulator. We provide a methodology for ...

Passive Dynamic Walking overcomes elegantly several drawbacks of the high gain position control approach to generate bipedal gait of robots. In this scenario the Limit Cycle Walking concept leads to the generation of high ...

We find that a symbolic walk (SW) - performed by a walker with memory given by a Bernoulli shift - is able to distinguish between the random or chaotic topology of a given network. We show this result by means of studying ...

Individuals after stroke remain with several long-term disabilities. In this sense, therapeutic approaches should be implemented for a broad view of the deficiencies in structure and body function, and limitations in ...
