Transformable

Although 3D printers can produce a wide variety of objects, the size of each item is limited by the size of the printer. Scientists have now developed a way of getting around that limitation, using a resin that expands when heated.

While dashboard-integrated trays are useful for storing items such as sunglasses, they can also add to a sense of in-car clutter. With this in mind, German scientists have created a tray that flattens into the dash when not required.

Renault has offered its take on what personal mobility might look like from 2025 with the Morphoz, an electric crossover that can morph between city and extended travel modes, can be wirelessly charged, and is ready for ride sharing.

After a successful Kickstarter last year, Robosen Robotics has launched the T9, a robot that transforms into a vehicle through voice commands or via an app.

Air travel can be difficult for the mobility-challenged … they have to get a wheelchair at the airport, or make sure that theirs gets stowed. Engineer Richard Williams has developed an alternative: a folding wheelchair that doubles as a carry-on bag.

It would be handy if there was a filtration medium that could be electronically "switched" to capture particles of different sizes. It turns out that there soon may be, thanks to a newly-developed conductive polymer that changes state, on demand.

The Tricksy is designed to serve as both a cargo trike and a shopping cart.

​VTOL (vertical take-off and landing) drones already have some advantages over multicopters and fixed-wing drones, but could they offer even better functionality? The designers of the ROTORwing seem to think so, as their aircraft's wings actually double as its rotor blades.

​If cycling helmets weren't so bulky to carry around, it's entirely possible that more people would actually use the things. That's why British cyclists Josh Cohen and Dom Cotton invented the Cyclo, which features a unique "flipclip" design.

​While regular multicopter drones are highly stable and maneuverable, their vertical take-off and landing (VTOL) counterparts are faster and more energy-efficient when in forward flight. Germany's Quantum Systems has set out to combine the best of both worlds, with its 2-in-1 Vector/Scorpion drone.

Dutch design firm Studio Rotor has been working with startup Retter Helfer Medical on a lightweight patient transport option for ambulance personnel. The Multi Scoop Pro features a patented mechanism that sees it change from flat stretcher to wheelchair in a matter of seconds.

​While many people use cargo bikes to haul their small children from place to place, how do they cart their tykes around upon reaching their destination? Well, in the case of the Dragonfly 2in1, the kid-carrying cabin simply detaches from the rest of the bike, becoming a stroller.
