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 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 architecture, easier control, faster motion and lower cost.

Multiple chains (limbs) connect the moving object to the base of parallel manipulators. [8] Most Cartesian coordinate robots are fully serial or a combination of serial and parallel connected linkages. However, there are some Cartesian coordinate robots that are fully parallel-connected. [9] [10] [11]
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 ...
Serial and parallel manipulator systems are generally designed to position an end-effector with six degrees of freedom, consisting of three in translation and three in orientation. This provides a direct relationship between actuator positions and the configuration of the manipulator defined by its forward and inverse kinematics.
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. the y -axis follows from the x - and z -axes by choosing it to be a right-handed coordinate system .
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 ...
