Abstract The cardioid crank is a planetary mechanism that generates line. It with varying length and speed moves along the used to replace of rocker mechanism, its approximate uniform motion obtained. kinematic analysis method studied in this paper. calculating for limit position oscillating angle time ratio guide bar are given. Finally, conditions synthesis put forward accordance or oscillate ...

as a robot could be stable statically standing on three or more legs, a six legged walking robot can be highly flexible in movements and perform different missions without dealing with serious kinematic and dynamic problems. an experimental six legged walking robot with 18 degrees of freedom is studied and built in this paper. the kinematic and gait analysis formulations are demonstrated by an e...

In this paper, kinematic characteristics of writing are compared in 5 patient with writer’s cramp who performed a set of standardized writing task. The kinematic characteristics thumb and forefinger force before and during cramp. The effect of writing on different inclined supporting surfaces is also investigated. Our results indicate that inclined surfaces aspects of writing discomfort in writ...

BACKGROUND Abnormal biomechanics have been cited as a potential risk factor for running-related injury. Many modifiable biomechanical risk factors have also been proposed in the literature as interventions via gait retraining. AIM To determine which interventions have successfully modified biomechanical variables linked to running-related injury. STUDY DESIGN Systematic literature review. ...

This paper presents the kinematics of a planar multibody vehicle which is aimed at the exploration, data collection, non-destructive testing and general autonomous navigation and operations in confined environments such as pipelines. The robot is made of several identical modules hinged by passive revolute joints. Every module is actuated with four active revolute joints and can be regarded as ...

passive distributed electro-optical systems with FPA based on a group of moving objects distributed in space are discussed. During the paradigm of such systems interpretation synthesis, the authors based on synergy and cybernetics. It can be explained by two factors: first – the distributed network-centric system is measuring-information system, and second – it is heterogeneous system (the syst...

High integrity localization system is an important challenge to improve safety for road vehicles. A way to meet the requirements is to fuse information from several sensors, from position and orientation sensors to motion, speed and acceleration sensors. This paper tackles the problem of vehicle motion estimation using monocular vision. A geometric model of the road is used to learn a texture p...

The low-mass end of the stellar Initial Mass Function (IMF) is constrained by focusing on the baryon-dominated central regions of strong lensing galaxies. We study in this letter the Einstein Cross (Q2237+0305), a z=0.04 barred galaxy whose bulge acts as lens on a background quasar. The positions of the four quasar images constrain the surface mass density on the lens plane, whereas the surface...

Control for and interaction with humanoid robots is often restrictive due to limitations of the robot platform and the high dimensionality of controlling systems with many degrees of freedom. We focus on the problem of providing a “skill-level interface” for a humanoid robot. Such an interface serves as a i) modular foundation for structuring task-oriented control, ii) parsimonious abstraction ...

In this paper we introduce a task‐based method for designing underactuated multi‐joint prosthetic hands for specific grasping tasks. The designed robotic hands or prosthetic hands contain fewer independent actuators than joints. We chose a few specific grasping tasks that are frequently repeated in everyday life and analysed joint motions of the hand during the co...
