This is the manufacturing prototype for the flapping wing mechanism designed by Peter Wang and modeled by Benjamin Liu. The wing is 5cm in length to match the dimensions of a hummingbird.

This is an animation by Benjamin Liu of a spatial RPR-2SS six-bar linkage designed by Peter Wang for use on tunnel boring machines. This new device controls a valve that cleans and closes the soil conditioning port when the flow of soil lubricant is stopped. Soil conditioning provides lubricant to manage the cutting operation. This self-cleaning valve stops clogging of the port which is a common problem.
This video shows the excellent research in design at universities in Beijing. This is the final of five videos highlighting design research across China taken during a visit in September 2016.
For our colleagues in China, here is a link to a YouKu version.
