Kinetic Cyclic Scissors | Hackaday

[Henry Segerman] and [Kyle VanDeventer] merge math and mechanics to create a kinetic cyclic scissors sculpture out of 3-d published bars adjoined along side M3 bolts and nuts.

a kinetic bar framework with 3d printed bars of alternative black and grey color, each joined with m3 bolts and nuts being held by a person at two points with a quadrilateral tiling overlay

The kinetic sculpture will also be regarded as part of a vast tiling of self an identical quadrilaterals within the airplane. The tiling of the airplane through those self an identical quadrilaterals will also be discovered as a framework through becoming a member of the diagonal issues of every quadrilateral with bars. The elemental query [Henry] and [Kyle] sought after to respond to was once below what stipulations can the discovered bar framework of a subsection of the tiling be made to transport. Unusually, when the quadrilateral is a parallelogram, like in a forklift, or “cyclic”, when the endpoints lie on a circle, the bar framework can transfer. Tweaking the ratios of the center lengths in a cyclic configuration ends up in various kinds of rotational symmetry that may be accomplished because the construction folds in on itself.

[Henry] and [Kyle] cross into extra element of their Bridges Convention paper, with derivations and additional discussions in regards to the symmetry precipitated through adjusting the limitations. The main points are gentle on the true kinetic sculpture featured within the video however the bar framework was once selected to have a replicate form of symmetry with a motor connected to probably the most central, decrease bars to force the motion of the sculpture.

The bar framework is to be had for obtain for any person in need of to 3-d print or laser reduce their very own. Bar frameworks are helpful concepts and we’ve observed them utilized in artwork sculptures to strandbeests, so it’s nice to look additional explorations on this area.
