Biped Walking Using Coronal and Sagittal Movements Based on Truncated Fourier Series [chapter]

Nima Shafii, Luís Paulo Reis, Nuno Lau
2011 Lecture Notes in Computer Science  
Biped walking by using all joint movements and DOFs in both directions (sagittal plane and coronal plane) is one of the most complicated research topics in robotics.  ...  In this paper, angular trajectories of a stable biped walking for a humanoid robot are generated by a Truncated Fourier Series (TFS) approach.  ...  An optimized Truncated Fourier Series is used to produce leg movements in sagittal plane and a model for swinging arms. A new model was also used to generate legs walking movement in coronal plane.  ...

The exchange between PE and KE of bCOM during walking gaits occur in a similar fashion from bipeds to octopods, with an energy recovery percentage up to 70% (maximum in walking bipeds) Cavagna and Kaneko  ...  The inverted pendulum model, which applies to walking gaits, is based on the out of phase fluctuation of PE and KE over a stride.  ...

The aim of the present study was to collect longitudinally data from a large group of infants (>20) using inertial sensors over a 6-months period after the onset of independent walking.  ...  This database will allow evaluating the changes in gait temporal parameters, stability and coordination at the beginning of independent walking.  ...  Jacob Seagull, and Mr. Cooper Greene on this study.  ...

Dynamic balance of bipedal robot based on central pattern generators and deep reinforcement learning

Christos Kouppas
SARAH was able to learn through experience both before and after deployment, which makes it ideal for commercial use, as it could learn based on its introduction within an environment.During the project  ...  One of the most recent bipedal robots, despite that is 12 years old, is NAO robot with a height less than 60cm.  ...  The left image represents the movement of the CoM in the sagittal plane while the right image presents the movement in the coronal plane.  ...
