This work presents an in-depth numerical investigation into a hypothesized two-layer central pattern generator (CPG) that controls mammalian walking and how different parameter choices might affect the stepping of a simulated neuromechanical model. P

Engineering neural networks to perform specific tasks often represents a monumental challenge in determining network architecture and parameter values. In this work, we extend our previously-developed method for tuning networks of non-spiking neurons

Animal locomotion is influenced by a combination of constituent joint torques (e.g., due to limb inertia and passive viscoelasticity), which determine the necessary muscular response to move the limb. Across animal size-scales, the relative contribut

Abstract Background Implanted motor system neuroprostheses can be effective at increasing personal mobility of persons paralyzed by spinal cord injuries. However, currently available neural stimulation systems for standing employ patterns of constant

A dynamical model of an animal’s nervous system, or synthetic nervous system (SNS), is a potentially transformational control method. Due to increasingly detailed data on the connectivity and dynamics of both mammalian and insect nervous systems, c

This work demonstrates a neuromechanical model of rat hindlimb locomotionundergoing nominal walking with perturbations. In the animal, two types of responses toperturbations are observed: resetting and non-resetting deletions. This suggests that the

This article presents experimental test results for joints used in a biomimetic bipedal robot. In this work, magnetic resonance imaging (MRI) and computed tomography (CT) scans are utilized to inform the design of joints of similar size and function

This work presents a biomechanical model of rat hind limbs with biarticular muscles and includes kinematic and kinetic analyses. Our previous model only possessed antagonistic muscle pairs (extensor and flexor) to actuate each joint in the sagittal p

This work demonstrates an algorithm that is able to compute optimal placement for braided pneumatic actuators on a bipedal robot in order to emulate the biology of human legs. The algorithm calculates the torque that muscles are able to generate abou
