BIO-INSPIRED CONTROL METHODOLOGY OF WALKING FOR INTELLIGENT PROSTHETIC KNEE

by Prof G. C. N, Bhaskar Gupta
"... Abstract: A detail analysis of bio inspired human walk keeping active prosthetic leg in mind has been presented. In existing advanced Active Knee prostheses the stiffness and damping at the prosthesis knee joint are applied by hydraulic and pneumatic cylinders. The damping of cylinders is controlled ..."
Abstract - Add to MetaCart
the above problem in a bio-inspired manner and also endeavoured various soft-computing techniques presently being used in biped locomotion for the use in prosthesis. An attempt to implement neural architecture controller using Central Pattern Generator (CPG) for prosthesis has been made. Earlier we thought

Using computed muscle control to generate forward dynamic simulations of human walking from experimental data.

by Darryl G Thelen , Frank C Anderson - J Biomech, , 2006
"... Abstract The objective of this study was to develop an efficient methodology for generating muscle-actuated simulations of human walking that closely reproduce experimental measures of kinematics and ground reaction forces. We first introduce a residual elimination algorithm (REA) to compute pelvis ..."

A critical role for the right fronto-insular cortex in switching between central-executive and default-mode networks.

by Devarajan Sridharan , † ‡ , Daniel J Levitin , Vinod Menon - Proc Natl Acad Sci USA , 2008
"... Cognitively demanding tasks that evoke activation in the brain's central-executive network (CEN) have been consistently shown to evoke decreased activation (deactivation) in the default-mode network (DMN). The neural mechanisms underlying this switch between activation and deactivation of larg ..."

observed significant activation of the CEN and deactivation of the DMN, along with activation of a third network comprising the right fronto-insular cortex (rFIC) and anterior cingulate cortex (ACC), when participants perceived salient auditory event boundaries. Using chronometric techniques and Granger

Straight Leg ged Walking of a Biped Robot

by Ryo Kurazume, Shuntaro Tanaka, Masahiro Yamashita, Tsutomu Hasegawa
"... Abstractm This paper presents a new methodology for gener-ating a straight legged walking pattern for a biped robot utilizing up-and-down motion of an upper body. Firstly, we define two new indexes, the Knee Stretch Index (KSI) and the Knee Torque Index (KTI), which indicate how efficiently the knee ..."

Through the Development of a Biomechatronic Knee Prosthesis for Transfemoral Amputees: Mechanical Design and Manufacture, Human Gait Characterization, Intelligent Control Strategies and Tests

by Rafael R Torrealba , Member, IEEE Claudia Pérez-D'arpino , José Cappelletto , Leonardo Fermín-León , Member, IEEE Gerardo Fernández-López , Juan C Grieco
"... Abstract-This paper presents the development of a biomechatronic knee prosthesis for transfemoral amputees. This kind of prostheses are considered 'intelligent' because they are able to automatically adapt their response at the knee axis, as a natural knee does. This behavior is achieved ..."
Abstract - Add to MetaCart
prostheses, gait cycle characterization is based on accelerometers signals processed by an events detection algorithm. Two intelligent control strategies are presented: a bio-inspired approach, that consists of using a central pattern generator to generate a knee angle reference to be followed

Optimizing the Gait of a Humanoid Robot Towards Human-like Walking

by Sven Wehner, Maren Bennewitz
"... Abstract — Achieving a stable, human-like gait with a humanoid robot is a challenging problem. While several rather simple as well as more complex techniques exist to generate stable walking patterns, only little attention has been paid towards the resemblance to the human gait. Popular gaits, for e ..."

Estimation of Forces and Moments of Lower Limb Joints from Kinematics Data and Inertial Properties of the Body by Using Inverse Dynamics Technique

by Subhra Chowdhury, Neelesh Kumar
"... Abstract: In this paper, the forces and its moments acting on hip, knee & ankle joints of the body have been estimated with the help of kinetic models for better biomechanics understanding of human gait. This helps in accurate measurement of segmental masses, acceleration, joint centers and mome ..."

and moment of inertia acting at various joints. Free Body Diagram (FBD) and Link Segment Model (LSM) are used for computing forces & moments using Inverse Dynamics (ID) technique. Available lower limb walking model is limited in terms of number of joint forces and moments are analyzed; so, the improved

Synthesis of a Walking Primitive Database for a Humanoid Robot using Optimal Control Techniques

by J. Denk, G. Schmidt , 2001
"... This paper presents a general method for generating walking primitives for anthropomorphic 3D--bipeds. Corresponding control torques allowing straight ahead walking with pre--swing, swing, and heel--contact are derived by dynamic optimization using a direct collocation approach. The computed torques ..."
