Concept of a Series-Parallel Elastic Actuator for a Powered Transtibial Prosthesis
The majority of the commercial transtibial prostheses are purely passive devices. They store energy in an elastic element during the beginning of a step and release it at the end. A 75 kg human, however, produces on average 26 J of energy during one stride at the ankle joint when walking at normal cadence and stores/releases 9 J of energy, contributing to energy efficient locomotion. According ...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
Within-socket myoelectric prediction of continuous ankle kinematics for control of a powered transtibial prosthesis.
OBJECTIVE Powered robotic prostheses create a need for natural-feeling user interfaces and robust control schemes. Here, we examined the ability of a nonlinear autoregressive model to continuously map the kinematics of a transtibial prosthesis and electromyographic (EMG) activity recorded within socket to the future estimates of the prosthetic ankle angle in three transtibial amputees. APPROA...
متن کاملSpeed adaptation in a powered transtibial prosthesis controlled with a neuromuscular model.
Control schemes for powered ankle-foot prostheses would benefit greatly from a means to make them inherently adaptive to different walking speeds. Towards this goal, one may attempt to emulate the intact human ankle, as it is capable of seamless adaptation. Human locomotion is governed by the interplay among legged dynamics, morphology and neural control including spinal reflexes. It has been s...
متن کاملThe AMP-Foot 2.0 : A Powered Transtibial Prosthesis That Mimics Intact Ankle Behavior
Almost all of the transtibial prostheses that are available on the market are purely passive devices. These prostheses store (potential) energy in an elastic element during the controlled dorsiflexion phase of stance and release it right after in order to move the body forward. As a result of this, only the energy which has been stored can be used for push-off and thus for propulsion. There exi...
