This study proposes a design approach and the development of low-power planar biped robot named YU-Bibot. The kinematic structure consists six independently driven axes, it weighs approximately 20 kg. Based on biomimetics, dimensions were selected as average anthropomorphic human lower extremities. optimization mechanical actuator selection was based results parametric simulations. natural walk...

Axis is a term for many things: the axis of cart, rotation, coordinates, symmetry... Originally, was part cart to which wheels are attached. In it visible and material, but more often understood as an imaginary straight line, gives idea peculiarities formation object ways its ordering. It naive think that order forming-up architectural subject only architect’s own will, architects draw they wis...

The introduction of biplane fluoroscopy has created the ability to evaluate in vivo motion, enabling six degree-of-freedom measurement tibiotalar and subtalar joints. Although International Society Biomechanics defines a standard method assigning local coordinate systems for ankle joint complex, standards joints are lacking. objective this systematic review was summarize appraise existing liter...

Human locomotion dynamics has been a topic of interest since the past few decades. In many areas such as as humanoid robot design, gait rehabilitation, diagnosis of pathologies, prosthesis design, sport analysis, and motion cognition, the human locomotion is needed to be properly modelled. Dynamics of human locomotion, and the capability of implementing an accurate human gait simulation can be ...

Stationary robotic trainers are lower limb rehab robots which often incorporate an exoskeleton attached to a stationary base. The aim is recover range of motion, increase muscles strength and reduce joint stiffness. issue observed in the stationery involve knee ankle-foot complex joints simultaneously that they restrict natural motion trainings due insufficient Degrees Freedom (DOFs) these trai...

this study was aimed to investigate the bending moment and stress (inner and outer corners) in lshaped biscuit joint made of solid wood, particleboard and medium density fiberboard (mdf). for this purpose, l-shaped joints made of beech and fir, particleboard and mdf by biscuit size numbers of 0 (47×15×3.8 mm), 10 (53×19×3.8mm) and 20 (60×23×3.8mm). bending moment and stress carrying capacity of...

This paper presents an approach to analytically determine the most energy efficient toolpath strategy in mechanical machining. This was achieved by evaluating the electrical energy requirement of the NC codes generated for the zag, zigzag, and rectangular contour toolpath strategies. The analytical method was validated by performing pocket milling on AISI 1018 steel with the considered toolpath...

background: the sternoclavicular joint (scj) is the only synovial articulation between the upper extremity and the trunk. this joint is one of the most frequently used joints, so osteoarthritis (oa) should be very common. however, there are few studies about oa in this joint.   methods: in this study, 48 sternoclavicular joints from the left and right joints of 23 cases and two left joints from...
