Short summary
Rigid-flexible coupling is the development trend of lightweight parallel mechanisms. To solve the kinematic problems of such mechanisms, this paper takes the rigid-flexible coupling parallel mechanism driven by elastic thin rods as the research object, proposes an inverse geometrico-static problem (IGP) solution, and conducts relevant motion tests to verify that the solution has high accuracy. This paper can effectively solve the IGP and provide theoretical support for practical application.
