Micro-Linkages for a Compliant Material

Micro-Linkages for a Compliant Material

Lucas Shaw and Prof. Jonathan Hopkins show the micro-architecture of an actively compliant material. Micro-actuators within the unit cells of an assembly are coordinated to reshape the assembly as desired. This was presented as part of the 2015 ASME Design Engineering Technical Conferences in Boston, MA, August 2-5. The video below shows what this assembly can do.

An Interesting Planar Robot at Laval

Students of Prof. Clement Gosselin at the Laval University Robotics Laboratory demonstrate a four-degree of freedom planar robot. I particularly like the demonstration of its use as a gripper that does a cartwheel just for fun.

Eight-bar Port Closure Tool

Eight-bar Port Closure Tool

This port closure tool curls back on itself to provide internal stitches to close a trocar port used for non-invasive surgery. This is the result of a collaboration between Kaustubh Sonawale and Jon Stokes.

Linkage Design for Wing Flapping

Linkage Design for Wing Flapping

Mark Plecnik shows that six-bar function generators can be used to drive a serial chain and produce a realistic wing flapping gait. Using trajectories obtained through video analysis by researchers Bret W. Tobalske and Kenneth P. Dial, “Flight Kinematics of Black-billed Magpies and Pigeons Over A Wide Range of Speeds,” Mark constructed functions for the joints of the serial chain, designed the function generators, and animated the results. Select this link for more information on Mark Plecnik and his work.
