Kaustubh Sonawale designed this four-bar linkage to move a truck spare tire from a stowed position to the deployed position.
Animations of linkage movement.
Oscar Alonso replaced the parallelogram drive linkages of the three-panel Volve C70 hardtop convertible with quadrilateral linkages, so it deploys farther and stows more compactly. The wheelbase of this vehicle approaches that of the Mercedes CL500. He used our Mathematica linkage synthesis notebook and our Mechanism Generator add-in for SolidWorks.
Here is something new. Our Mathematica notebook can find defect-free spherical four-bar linkages that guide a body through five orientations in a tolerance zone near a specified set of task orientations.
This shows the operation of our Mathematica notebook for five-position synthesis of a four-bar linkage. The link to download and try this notebook is on our Linkage Synthesis page.
This SolidWorks animation of the drive linkage for a hardtop convertible was prepared by Oscar Alonso from U.S. Patent No. 7014247 (Dilluvio) and previous references.
This six-bar linkage was designed to extend from the body of an underwater ROV to retrieve and stow objects positioned by a robotic arm.
This compact six-bar linkage is designed to lift and dump a trash can. Eddie Lee, Peter Lim, Khemara Tep and Kevin Hung worked on the design and construction of the prototype.
This is the SolidWorks animation:
This is a video of the operation of the prototype:
This six-bar linkage is designed to move a shelf from a position down and forward to a stowed position up and away.
This video shows our latest model for the six-bar linkage that deploys and stows a television monitor. This was designed and built by Eddie Lee, Peter Lim, Khemara Tep and Kevin Hung.
This is a SolidWorks animation of this six-bar linkage:

Mechanism Generator is a SolidWorks add-in that assists in generating solid models of four-bar and six-bar linkages. It designed to be used in coordination with our Mathematica design software, which is freely available.
