This paper deals with kinematics and dynamics of the human shoulder in order to obtain the workspace related to the reachability of the wrist and applications to determine load for the wheelchair. The model contains six revolute degrees of freedom (D.O.F), two in costoclavicular and three in the shoulder joint and one in the elbow joint, while a six D.O.F model was developed according to given ...

The purpose of this study was to describe biomechanical parameters of head, upper and lower body extremities during a straight right punch throw related to performance and injury mechanism. Subjects were eight elite right-handed male (age 20.4 ± 2.1yrs height 177.4 ± 8.5 cm mass 70.4 ± 16.8 kg) amateur boxers. 3D motion analysis was used to assess the kinematics of the right side extremities ...

Krill are aquatic crustaceans that engage in long distance migrations, either vertically in the water column or horizontally for 10 km (over 200,000 body lengths) per day. Hence efficient locomotory performance is crucial for their survival. We study the swimming kinematics of krill using a combination of experiment and analysis. We quantify the propulsor kinematics for tethered and freely swim...

Inverse kinematics computation using an artificial neural network that learns the inverse kinematics of a robot arm has been employed by many researchers. However, the inverse kinematics system of typical robot arms with joint limits is a multi-valued and discontinuous function. Since it is difficult for a wellknown multi-layer neural network to approximate such a function, a correct inverse ki...
