Fabrication: 04 Soldering

Smitty presents the basic techniques of soldering. Every mechanical system includes electronic parts and careful soldering is critical to ensuring things do not come loose in operation.

Chop Wood Carry Water, S1:E9

The explosions had stopped for good, I believed. It had been an hour since I’d heard any noise at all. I carefully picked my way up along the steep transport track to the top of the cliff. It was nearly dawn, but a full moon had risen and to the west the sky was still […]

Flapping Wing Mechanism

Benjamin Liu prepared this animation of the flapping wing mechanism designed by Peter Wang. It controls both the swing and the pitch of the wing to improve aerodynamics in hovering flight. This is the Youtube version of the animation. The youku version for our Chinese colleagues is available at the link: Hummingbird Linkage.

Linkages draw Bezier curves

Here is an example of our Bezier curve drawing linkages. The first draws Yang Liu’s first name in cursive. Rather than show the linkages all at once, they are separated so it is easier to see the curves that they draw. Also shown here is the linkage that draws the a cursive version of the […]

Design Research in China: Changzhou

Our trip through China concluded at a conference and workshop at Changzhou University. This video highlights the Changzhou conference on innovation in Robotics and Intelligent Manufacturing, the beauty of the city of Changzhou, and a rainy night in Shanghai. Our colleagues in China can see this video on YouKu at: Design Research in China: Changzhou
