Toward the enhancement of biped locomotion and control techniques:walking pattern classifi cation

2011-01-01
A new walking pattern classification method is proposed for a 5-link 7-DOF biped robot walking on an uneven floor. This method extracts the patterns in the current floor position of the stance foot and the transitioning floor conditions of the swing foot during locomotion. When a global path composed of stairs, obstacles, etc., and certain walking parameters, such as the speed of walking and the total walking time, are put into the system, the guidance controller unit determines the trajectory of the footsteps in terms of step patterns by using a genetic algorithm-based optimization technique while ensuring the biped's stability criterion. A demonstration of the biped with different pattern classes was realized by a dynamic simulator. © 2011 International Symposium on Artificial Life and Robotics (ISAROB).

Analysis of wave gaits for energy efficiency
Erden, Mustafa Suphi; Leblebicioğlu, Mehmet Kemal (2007-10-01)
In this paper an energy efficiency analysis of wave gaits is performed for a six-legged walking robot. A simulation model of the robot is used to obtain the data demonstrating the energy consumption while walking in different modes and with varying parameters. Based on the analysis of this data some strategies are derived in order to minimize the search effort for determining the parameters of the gaits for an energy efficient walk. Then, similar data is obtained from an actual experimental setup, in which ...
Identification of a vertical hopping robot model via harmonic transfer functions
Uyanik, Ismail; Ankaralı, Mustafa Mert; Cowan, Noah J.; Saranlı, Uluç; Morgul, Omer (2016-05-01)
A common approach to understanding and controlling robotic legged locomotion is the construction and analysis of simplified mathematical models that capture essential features of locomotor behaviours. However, the representational power of such simple mathematical models is inevitably limited due to the non-linear and complex nature of biological locomotor systems. Attempting to identify and explicitly incorporate key non-linearities into the model is challenging, increases complexity, and decreases the ana...
Dynamic gait pattern generation with reinforcement learning
Erden, Mustafa Suphi; Leblebicioğlu, Mehmet Kemal (2005-01-01)
This paper presents the gait pattern generation work performed for the sixlegged robot EA308 developed in our laboratory. The aim is to achieve a dynamically developing gait pattern generation structure using reinforcement learning. For the six legged robot a simplified simulative model is constructed. The algorithm constructs a radial basis function neural network (RBFNN) to command proper leg configurations to the simulative robot. The weights of the RBFNN are learned using reinforcement learning. The dev...
Dynamic Modeling and Control of Underactuated Planar Bipedal Walking
Sovukluk, Sait; Ankaralı, Mustafa Mert; Saranlı, Uluç; Department of Electrical and Electronics Engineering (2022-6-16)
This study demonstrates an adaptive model predictive control method for input constrained control of underactuated bipedal walking with a predefined trajectory. Our approach aims to increase the trajectory tracking performance of the system and produce realistic and applicable responses while letting a certain amount of posture change around the predefined trajectory. To do so, we employ whole-body dynamics in our control structure, include weights for the unactuated joint inside the cost function, and defi...
