Parallel kinematic device for connecting fixed platform to mobile platform uses three connecting elements engaging with common point of one of platforms to form a triple point with simple mechanical configuration

摘要

The kinematic device uses three connecting elements to engage with a common point of one of the platforms (2,3) forming a triple point (P3). The triple point can be configured to produce simple mechanical configuration. Each of the three connecting elements engages per se close to the engagement points of the two other connecting elements on the movable platform. One connecting element engages on one point of the movable platform, the second connecting element engages on this connecting element close to its engagement point on the movable platform and the third connecting element engages on the first element close to the engagement point of the second.
