Virtual Reality (VR) technology offers users the possibility to immerse and freely navigate through virtual worlds. An important component for achieving a high degree of immersion in VR is locomotion. Often discussed literature, natural effective way controlling locomotion still general problem which needs be solved. Recently, headset manufacturers have been integrating more sensors, allowing h...

Objective(s): We aim to examine possible ammonia lowering effects of mesoporous silica SBA-15 in rats after the common bile duct ligation (BDL). We also evaluate the effect of SBA-15 treatments during 28 days of BDL on locomotion and rearing behavior, as well as on the gene expression of Jnk3 and p38alpha (p38α) mitogen-activated protein kinases in the prefrontal corte...

A Grasp-based Motion Planning Algorithm for Intelligent Character Animation Maciej Kalisiak Master of Applied Science Graduate Department of Electrical & Computer Engineering University of Toronto 1999 The automated animation of human characters continues to be a challenge in computer graphics. We present a novel kinematic motion planning algorithm for character animation which addresses some o...

Birds, fish and other animals routinely use unsteady effects to save energy by alternating between phases of active propulsion and passive coasting. Here, we construct a minimal model for such behaviour that can be couched as an optimal control problem via an analogy to travelling with a rechargeable battery. An analytical solution of the optimal control problem proves that intermittent locomot...

One of the outstanding challenges in soft robotics is the chicken-and-egg problem of body/brain design: generation of locomotion is predicated on the existence of a locomotioncapable body, and generation of body plans is predicated upon the existence of effective locomotion. This problem is compounded by the high degree of coupling between the material properties of a soft body (such as stiffne...

A general approach to optimal motion synthesis of constrained multibody systems is presented. It applies to controlled mechanical systems such as industrial manipulators and legged-locomotion systems. An optimal control problem is stated. A parametric optimization technique based on approximating joint motion coordinates using spline functions of class C is developed to recast this primary prob...

Abstract The wearable lower limb exoskeleton is a typical human-in-loop human–robot coupled system, which conducts natural and close cooperation with the human by recognizing locomotion timely. Requiring subject-specific training main challenge of existing approaches, most methods have problem insufficient recognition. This paper proposes an integral subject-adaptive real-time Locomotion Mode R...
