Cartesian parallel manipulators are in the intersection of two broader categories of manipulators: Cartesian and parallel. Cartesian manipulators are driven by mutually perpendicular linear actuators. They generally have a one-to-one correspondence between the linear positions of the actuators and the X, Y, Z position coordinates of the moving ...
A parallel manipulator is a mechanical system that uses several computer-controlled serial chains to support a single platform, or end-effector. Perhaps, the best known parallel manipulator is formed from six linear actuators that support a movable base for devices such as flight simulators.
A full parallel manipulator can move an object with up to 6 degrees of freedom (DoF), determined by 3 translation 3T and 3 rotation 3R coordinates for full 3T3R mobility. However, when a manipulation task requires less than 6 DoF, the use of lower mobility manipulators, with fewer than 6 DoF, may bring advantages in terms of simpler ...
Parallel manipulator – articulated robot or manipulator based on a number of kinematic chains, actuators and joints, in parallel. c.f. serial manipulator. Remote manipulator – manipulator under direct human control, often used for work with hazardous materials. Serial manipulator – articulated robot or manipulator with a single series ...
Degrees of freedom - the extent to which a robot can move itself; expressed in terms of Cartesian coordinates (x, y, and z) and angular movements (yaw, pitch, and roll). [3] Delta robot - a tripod linkage, used to construct fast-acting manipulators with a wide range of movement. Drive Power - The energy source or sources for the robot actuators ...
The x-axis is parallel to the common normal: = (or away from z n–1) If there is no unique common normal (parallel z axes), then d (below) is a free parameter. The direction of x n is from z n–1 to z n, as shown in the video below.
This robot features two parallel rotary joints to provide compliance in a plane. Articulated robot: Used for assembly operations, diecasting, fettling machines, gas welding, arc welding and spray-painting. It is a robot whose arm has at least three rotary joints. Parallel robot: One use is a mobile platform handling cockpit flight simulators ...
Cartesian coordinate robots are controlled by mutually perpendicular active prismatic P joints that are aligned with the X, Y, Z axes of a Cartesian coordinate system. [ 6 ] [ 7 ] Although not strictly ‘robots’, other types of manipulators , such as computer numerically controlled (CNC) machines, 3D printers or pen plotters , also have the ...
