Kinematic Models for Digital Design Library (KMODDL)

KMODDL is the Kinematics Models for Design Digital Library developed at Cornell University. It includes open access, multimedia resources for learning and teaching about kinematics - the geometry of pure motion - and the history and theory of machines.

The KMODDL site was first released in 2003, and the materials are currently being reviewed for transfer to a different platform. In the meantime, the original site has been archived and is made available via the WayBack Machine Archive-It service: http://wayback.archive-it.org/2566/20180418122029/http://kmoddl.library.cornell.edu/

NOTE: not all resources or navigation are functional on this archived version of the KMODDL website. Please contact us if you have questions about using this resource.

The original core of KMODDL is the Reuleaux Collection of Mechanisms and Machines, an important collection of 19th-century machine elements held by Cornell University’s Sibley School of Mechanical and Aerospace Engineering. The KMODDL digital library was originally developed as a collaborative grant with the faculty of Cornell Engineering, the Cornell University Library, and several external partners as a collection in the National Science Digital Library.
