The controllable workspace of a tendon-based Stewart Platform is the set of postures where forces ans torques at the end-effector can be controlled. A necassary and sufficent condition is given for those postures where forces can be controlled; thus, a superset of the controllable workspace can be calculated easily. External forces are modeled as an additional tendon fixed at infinity by introducing an unusual compactification of Rn that contains one infinitely distant point for each direction.
