HexaMorph: A Reconfigurable and Foldable Hexapod Robot Inspired by Origami

Wei Gao, Ke Huo, Jasjeet S. Seehra, Karthik Ramani, and Raymond J. Cipra
IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS'14) , Chicago, September, 2014

Origami affords the creation of diverse 3D objects through explicit folding processes from 2D sheets of material. Originally as a paper craft from 17th century AD, origami designs reveal the rudimentary characteristics of sheet folding: it is...

The evolution, challenges, and future of knowledge representation in product design systems

The evolution, challenges, and future of knowledge representation in product design systems

Senthil Chandrasegaran, Karthik Ramani, Ram D. Sriram, Imre Horvath, Alain Bernard, Ramy Harik, Wei Gao
Computer-Aided Design Volume 45, Issue 2, February 2013, Pages 204-228.

Abstract: Product design is a highly involved, often ill-defined, complex and iterative process, and the needs and specifications of the required artifact get more refined only as the design process moves toward its goal. An eff ective computer...
