MIT’s Crazy Materials Could Make for Self-Assembling Ikea Furniture

By Joseph Flaherty

To most people, the things Skylar Tibbits makes at MIT’s Self-Assembly Lab looks like nothing more than scraps of stuff. But where others see bits of wood and swatches of fabric, Tibbits sees robots. Lots and lots of robots.

They don’t have microprocessors, gleaming titanium skeletons, or an unhealthy obsession in Sarah Connor, but the wood panels and carbon fiber Tibbits’ team fabricates combine sensors, logic, and outputs in ways that could transform everything from airplanes to clothing to flat-pack furniture.

As its name suggests, the Self-Assembly Lab focuses on making things that can, well, self-assemble. It has created a series of small wood planks, for instance, that fold into a toy elephants when exposed to moisture. Tibbets and collaborators Christophe Guberan and Erik Demaine are working on clothing that could morph in response to the weather. In the future, the Lab’s research could make way for Ikea furniture that assembles itself with a splash of water—no Allen wrench required.

How 4-D Printing Works

Tibbits refers to these processes collectively as “4-D printing.” It’s like 3-D printing but with a fourth dimension: time, or as Tibbits likes to call it, “dynamism.” In the future, Tibbits thinks it will be possible to program all types of materials.

The tools Tibbits and company use are not especially novel. In the case of the carbon fiber projects, the manufacturing process is thoroughly two-dimensional. The team starts with a standard carbon fiber roll that follows the typical warp and weft pattern. A secondary material, formulated in Tibbet’s lab to respond to changes in temperature, is spot-printed on the mesh using a CNC gantry. As the carbon fiber is exposed to heat, the temperature-sensitive material changes shape and causes the sheet to deform in ways specified by the designer.

China Plans To Export J-31 Stealth Fighter
Nov. 10, 2014 - 12:05PM
By WENDELL MINNICK

ZHUHAI, CHINA — China plans to export its stealthy twin-engine J-31 fighter, which would become the first aircraft of its kind available to global customers who cannot afford the Lockheed Martin F-35. The fighter is similar in configuration to the single-engine F-35 stealth fighter.

The J-31 export revelation occurred in the Aviation Industry Corporation of China (AVIC) Exhibition Hall after personnel unwrapped its 1:2 model of the aircraft Nov. 10 during a preshow tour of this week’s Airshow China in Zhuhai. The placard for the model states: “FC-31 4th Generation Multi-Purpose Medium Fighter.”

Chinese fighters are designated with a “J” for fighter and “FC” for export,” and this is the first time the J-31 has been referred to as the FC-31.

Though overcast, a J-31 performed a demonstration flight during the preshow tour, as did the Russian Su-35 multirole fighter. China and Russia are expected to sign a deal for export of the Su-35 sometime later this month.

The 10th biennial China International Aviation and Aerospace Exhibition (Airshow China) has been an outlet for defense companies to market new products for export and for China’s military to show off sophisticated weapon systems. The Nov. 11-16 airshow has become the biggest commercial and defense airshow in Asia with over 700 companies exhibiting.

Science Daily

Tools and primates: Opportunity, not necessity, is the mother of invention

Date:
November 11, 2014

Source:
University of Cambridge

When food is scarce, tool use among non-human primates does not increase. This counterintuitive finding leads researchers to suggest that the driving force behind tool use is ecological opportunity -- and that the environment shapes development of culture.

Whether you're a human being or an orangutan, tools can be a big help in getting what you need to survive. However, a review of current research into the use of tools by non-human primates suggests that ecological opportunity, rather than necessity, is the main driver behind primates such as chimpanzees picking up a stone to crack open nuts.

An opinion piece by Dr Kathelijne Koops of the University of Cambridge and others, published today (12 November 2014) in Biology Letters, challenges the assumption that necessity is the mother of invention. She and her colleagues argue that research into tool use by primates should look at the opportunities for tool use provided by the local environment.

Koops and colleagues reviewed studies on tool use among the three habitual tool-using primates -- chimpanzees, orangutans and bearded capuchins.

Chimpanzees use a variety of tools in a range of contexts, including stones to crack open nuts, and sticks to harvest aggressive army ants. Orangutans also use stick tools to prey on insects, as well as to extract seeds from fruits. Bearded capuchin monkeys living in savannah-like environments also use a variety of tools, including stones to crack open nuts and sticks to dig for tubers.

The researchers' review of the published literature, including their own studies, revealed that, against expectations, tool use did not increase in times when food was scarce. Instead, tool use appears to be determined by ecological opportunity with calorie-rich but hard-to-reach foodstuffs, such as nuts and honey, appearing to act as an incentive for an ingenious use of materials.

"By ecological opportunity, we mean the likelihood of encountering tool materials and resources whose exploitation requires the use of tools. We showed that these ecological opportunities influence the occurrence of tool use. The resources extracted using tools, such as nuts and honey, are among the richest in primate habitats. Hence, extraction pays off, and not just during times of food scarcity," said Koops.

Tool use -- and transmission of tool-making and tool-using skills between individuals -- is seen as an important marker in the development of culture. "Given our close genetic links to our primate cousins, their tool use may provide valuable insights into how humans developed their extraordinary material culture and technology," said Koops.

It has been argued that culture is present among wild primates because simple ecological and genetic differences alone cannot account for the variation in behaviour -- such as tool use -- observed across populations of the same species.

Koops and co-researchers argue that this 'method of exclusion' may present a misleading picture when applied to the material aspects of culture.

"The local environment may exert a powerful influence on culture and may, in fact, be critical for understanding the occurrence and distribution of material culture. In forests with plenty of nut trees, we are more likely to find chimpanzees cracking nuts, which is the textbook example of chimpanzee material culture," said Koops.

"Our study suggests that published research on primate cultures, which depend on the 'method of exclusion', may well underestimate the cultural repertoires of primates in the wild, perhaps by a wide margin. We propose a model in which the environment is explicitly recognised as a possible influence on material culture."
