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...

A musculoskeletal model was developed to determine the theoretically optimal pedaling technique (quantified as pedal forces and kinematics) for sprint cycling. Input was a set of stimulation patterns for the eight major muscle groups in the lower extremity, output are the kinematics and forces predicted by a direct dynamics simulation. Stimulation patterns were optimized until maximal average p...

A novel n(4-SPS+SP) serial-parallel manipulator (S-PM) formed by n 4-SPS+SP PMs with four degrees of freedom (DOF) connected in series is proposed in this paper. The kinematics , statics and stiffness modeJ of this seriaJ-PM is established.

Background: Lumbar motion analysis is used as a clinical method in the diagnosis and treatment of low back pain (LBP). So far, no studies have shown if manipulating the sacroiliac joint (SIJ) will change spinal kinematics.Objective: The main objectives of this study were to investigate the effects of SIJ manipulation on the lumbar kinematics in subjects with innominate rotation and to compare l...

purpose to examine the intra-rater reliability of knee movement data in sagital plane obtained from electrogoniometer (egm) in a basic, sport-specific task of karate. methods a total of 23 elite karate athletes (13 females and 10 males; mean age of 16.10±1.26 yrs) participated in this study. the task was defined as performing three consecutive zenkutsu-dachi in two sessions. the used egm was a ...

objectives: investigating the effect of endurance training program onthe gait pattern of non-active elderly people. methods & materials: this study has been done by a semi-experience method with 23 old men and women by the average and standard deviation of 70/50±6/9 years old (n=14 people of exercise group, n=9 people of control group). the exercise group took part in this program for eight wee...

Robot motion planning has applications in a wide range of areas such as robot navigation and medical surgery. Among the topics that are related to motion planning, computing time-optimal trajectories is challenging and of great importance. We want to move a robot from the start to the goal in the shortest time. There are four different vehicle designs that are considered in our work: Dubins car...
