The kinematics of manipulators is a central problem in the automatic control of robot manipulators. Theoretical background for the analysis of the 5 Dof Lynx-6 educational Robot Arm kinematics is presented in this paper. The kinematics problem is defined as the transformation from the Cartesian space to the joint space and vice versa. The Denavit-Harbenterg (D-H) model of representation is used...
The current evaluation of the triple-α reaction rate assumes that the α decay of the 7.65 MeV, 0+ state in 12C, commonly known as the Hoyle state, proceeds sequentially via the ground state of 8Be. This assumption is challenged by the recent identification of two direct α-decay branches with a combined branching ratio of 17(5)%. If correct, this would imply a corresponding reduction in the trip...
objectives: the aim of this study was to extract suitable spatiotemporal and kinematic parameters to determine how total knee replacement (tkr) alters patients’ knee kinematics during gait, using a rapid and simplified quantitative two-dimensional gait analysis procedure. methods: two-dimensional kinematic gait pattern of 10 participants were collected before and after the tkr surgery, using a ...
Older adults frequently experience a decrease in balance control that leads to increased numbers of falls, injuries and hospitalization. Therefore, evaluating older adults' ability to maintain balance and examining new approaches to counteract age-related decline in balance control is of great importance for fall prevention and healthy aging. Non-invasive brain stimulation techniques such as tr...
The TwinCAT Supplement ‘TwinCAT Kinematic Transformation’ is presented in this application example. This supplement makes it possible to compute robot kinematics together with the PLC and Motion Control on one PC-based CPU. Analogous to the TwinCAT Motion Control package (integration of the drive control in the controller), a robot kinematics is configured and parameterised with the ‘Kinematic ...
This paper introduced design analysis of a new 5DOF surgical robot used for minimally invasive surgery. The kinematics modeling is studied by solving the forward and inverse kinematics of the robot using the Denavit-Hartenberg convention and geometrical method. Robot kinematics simulation is built by creating the 3D CAD model of the robot and patient, then a kinematic motion simulation of a sur...
This paper deals with kinematics, dynamics and power consumption analyses of a six-legged robot generating turning motions to follow a circular path. Direct and inverse kinematics analysis has been carried out for each leg in order to develop an overall kinematics model of the six-legged robot. It aims to estimate energyoptimal feet forces and joint torques of the sixlegged robot, which are nec...
