A good video game prop can really spruce up the decor — doubly so if it’s a glowing, futuristic potted plant transplanted(sorry!) straight from Deus Ex: Human Revolution.
Since it’s a bit difficult to grow neon light vines, this project is more lamp than plant. The maker with the green thumb is [Phil], from [JumperOneTV], and he is using five meters of warm white strip LEDs cut to varying vine lengths. He’s also procured a store-bought flower pot that conveniently mirrors the in-game model. The vines are made of 16mm polyethylene tubing which he’s shaped using a heat gun — setting their shape by pumping water through it — and secured in the pot with insulation foam. Feeding the LED strips through and wiring them in parallel was simple compared to his next conundrum: supplying the power.

Researchers have been playing around with various oddball forms of robot locomotion; surely, we’ve seen it all, haven’t we? Not so! Lucky for us, [researchers at Stanford] are now showing us a new way for robots to literally extrude themselves from point A to point B.
This robot’s particular motion for mechanism involves unwinding itself inside out. From a stationary base, a reel caches meters of the robot’s uninflated polyethylene body, which it deploys by pressurizing. Researchers can make full 3D turns by varying the amount of inflated air in outer control chambers. What’s more, they can place end effectors or even payloads at the tip of the growing end with their position held in place by a cable.
As we can imagine, any robot that can squeeze its way up to 72 meters long can have dozens of applications, and the folks at Stanford have explored a host of nooks and crannies of this space. Along the way, they deploy complex antenna shapes into the air, deliver small payloads, extinguish fires, and squeeze through all sorts of uninviting places such as flytraps and even a bed of nails. We’ve placed a video below the break, but have a look at Ars Technica’s full video suite to get a sense of the sheer variety of applications that they imparted upon their new creation.
Biomimetics tends to get us to cry “gecko feet” or “snake robots” without thinking too hard. But these forms of locomotion that come to mind all seem to derive from the animal kingdom. One key element of this soft robot is that its stationary base and vine-like locomotion both have its roots in the plant kingdom. It’s a testament to just how unexplored this realm may be, and that researchers and robots will continue to develop new ways of artificially “getting around” for years to come.
Thanks for the tip, [Jacob!]

The Vine app is all the rage these days. It lets you shoot six-second videos on your iPhone and easily post them on the Internet. The problem is that [Sean Hodgins] doesn’t find the time limit to be useful for traditional video. But you can cram a lot more info into a half-dozen seconds if you make it a time-lapse video. The rig above is his solution to making the Vine app act as a time-lapse recorder.
The trick is in how the app itself works. It only records video when you’re touching the screen. So you record one second of video, then remove your finger and it ‘pauses’ the recording until you’re ready for the next scene. [Sean] automated this by adding a servo motor and a stylus. An Arduino drives the servo, making quick taps on the screen to get as many different frames into the six seconds as possible. He had a bit of trouble registering quick taps at first. His solution was to inject 3.3V into the stylus he gutted for the project. Click through the link above to see some example videos, or watch this embedded video to see the hardware at work:
