MIT develops self-transforming materials that behave 'like robots without robots'

A cross-disciplinary research lab at the Massachusetts Institute of Technology (MIT) has developed a suite of programmable materials, including carbon fiber, printed wood grain, textile composites, rubbers and plastics, that self-transform when exposed to an external stimulus. Director of the Self-Assembly Lab, Skylar Tibbits, presented a TED talk on 4D printing in 2013, where he demonstrated how a flat sheet of material could effectively build itself when exposed to water, like a robot without a robot. Following positive feedback from industries including aviation, automotive and manufacturing, his lab has been working on developing materials that change according to different activation sources, including heat, light, and air pressure, in addition to water – all of which have automotive relevance.

Toyota Tundra: Toyota recalls 110,000 pickups on rusted-frame concern

Toyota Motor Corp. is recalling 110,000 Toyota Tundra pickups for the 2000 to 2003 model years after reports that rusted frames in cold weather may cause spare tires under the truck bed to break loose and fall onto the road. Corrosion of the rear cross-member, which supports the spare tire, also eventually may affect the rear brake line and lengthen vehicle stopping distances, increasing the risk of a crash, Toyota said in a statement Tuesday.
