Double the tensegrity, triple the trouble

Over the past few months, LEGO tensegrity sculptures have been all the rage, with their gravity-defying stacking attracting builders of all stripes to try their hands. While most tensegrity structures consist of a single floating element, a few builders have managed to add another floating section to that, which makes the delicate balancing exponentially more difficult. David Roberts makes it look easy, though, with this tower of rings.

The Three RingsTensegrity sculptures stay aloft thanks to being held in tension with three tethers (chains in this case), but David’s model also adds tension to the rings themselves, which simply comprise Technic tread links joined inside out to make a tensioned circle. It all comes together to create a beautifully simple sculpture.

Now, who wants to try their hand at creating a tensegrity sculpture with three floating levels on top of the base? Any takers?

The art and science of LEGO tensegrity builds

The recent trend in the LEGO-sphere community has all been about magical floating compression structures, better known as a tensegrity – a portmanteau of “tensional integrity”. The fad started with a very rudimentary build on a Reddit and soon spawned many more creative iterations. We pick a few of the more outstanding ones that we’ve seen that has impressed us. A couple of them come with build videos and instruction guides for you to build your very own.

Hot dog or hot rod?

Abandon all logic! David Roberts is back at his surreal best, with this fine meat-based entry to the Febrovery building event. David asks us why we wouldn’t want to drive around in a car shaped like a hot dog, and I really have no answer for him. Taking his inspiration from master children’s illustrator and author Richard Scarry, whose mad world saw anthropomorphic pigs at the wheel of just such vehicles, this build ticks all the LEGO fun boxes. Take a final moment to marvel at its mustard windshield, sausage chassis and wrap around bun – genius!

Built with ridiculous speed in mind

Described as the “biggest, baddest, most bulbous speeder bike”, by builder David Roberts, the Turbinia certainly lives up to its name. I’ve admired David’s work for a long time now, especially the way he mixes his humorous narratives with the knowledge of an engineering graduate. In this case the turbine element creates both the quirky nautilus-like shape of the vehicle, as well as hinting at the real-life mechanics of a centrifugal processor. Whichever way you look at it, this colourful model is a whole heap of gyroscopic fun.
