Forward Position Analysis of the 3-DOF Module of the TriVariant: A 5-DOF Reconfigurable Hybrid Robot

摘要

This paper deals with the forward position analysis of a 3-DOF parallel mechanism module, which forms the main body of a 5-DOF reconfigurable hybrid robot named TriVariant. The TriVariant is a modified version of the Tricept robot, achieved by integrating one of the three active limbs into the passive one. The analytical method is employed to obtain the forward position solutions. It shows that the forward position analysis of the TriVariant is much simpler than that of the Tricept.
