== Description ==

Cartesian parallel manipulators are in the intersection of two broader categories of manipulators: [[Cartesian coordinate robot|Cartesian]] and [[Parallel manipulator|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 platform, making them easy to control. Furthermore, Cartesian manipulators do not change the orientation of the moving platform. Most commonly, [[Cartesian coordinate robot|Cartesian manipulators]] are [[Serial manipulator|serial]]-connected; i.e., they consist of a single [[Linkage (mechanical)|kinematic linkage]] chain, i.e. the first linear actuator moves the second one and so on. On the other hand, Cartesian parallel manipulators are parallel-connected, i.e. they consist of multiple kinematic linkages. Parallel-connected manipulators have innate advantages<ref>Z. Pandilov, V.

The Tripteron 3-DoF member has three translation degrees of freedom ''3T'' DoF, with the subsequent members of the Multipteron family each adding a rotational ''R'' degree of freedom. Each member of the family has mutually perpendicular linear actuators connected to a fixed base. The moving platform is typically attached to the linear actuators through three geometrically parallel revolute ''R'' joints. See [[Kinematic pair]] for a description of shorthand joint notation used to describe manipulator configurations, like revolute ''R'' joint for example.
