This robot was composed of
a base and a triangular moving platform with three extensible links connecting the moving
platform to the base. These three extensible links were connected to the base platform by
Hooke’s joints with one actuated axis. Rotations of the active axes of the Hooke’s joints were
achieved by additional three extensible links. Later, all platform-based manipulators were
called Stewart-Gough platforms or, in short mistakenly, Stewart platforms.
