Degrees of Freedom (dof) – The number of independent coordinates required to define/constrain the position of all links with respect to ground. CRITICAL SECTIONS Formula for Calculating the Mechanism Mobility:the minimum number of independent parameters (coordinates) required to specify the position of...
11 used analytical methods to solve the inverse kinematics of redundant manipulators. To overcome the limitations of traditional methods, some intelligent algorithms are used in solving the inverse kinematics of robotic arms, such as heuristic algorithms, neural network algorithms, and other machine ...
(o-xyz) is fixed at the mass center of the bearing, and the inner race rotates around the z-axis with the speed ofωi. In regard to the inner race, its torsional degree of freedom is ignored, while three translational degrees of freedom about thex-axis,y-axis, andz-axis, two ...
These designs effectively remove the error accumulation due to serial kinematics, however, they often require a relatively large system volume and can suffer from the parasitic motion of coupled compliant mechanisms, which may limit their positioning accuracy and dynamic performance [13]. Among various...
The conclusion shows that the designed six-degree-of-freedom upper limb rehabilitation robot has the effect of rehabilitation training. 展开 关键词: Training Wrist Solid modeling Trajectory planning Robot kinematics Stroke (medical condition) Assistive robots Polynomials Mathematical models MATLAB 会议名称:...
This paper deals with the kinematics and dynamics analysis of a 6 degree-of-freedom RTS fully parallel manipulator with elastic joints. The elastic joints are used to realize highly precise operation. Rotary input is applied to drive six groups of four-bar linkages in this system. Two displaceme...
Evaluating the aerodynamic design of moving objects, such as ordnance, is often done using high-speed imagery on film or videotape. The imagery must then be analyzed to determine the position and orientation of the object in each frame; from this data, the trajectory, acceleration, and other ...
A Six-Degree-of-Freedom Parallel-Manipulator having three inextensible limbs for manipulating a platform is described in which the three inextensible limbs are attached via universal joints to the pla
