Optical Fibers and CRLD Bolts monitor deformation of a pit-in-pit foundation

A novel monitoring system for monitoring deep foundation pits and roof safety in underground coal mining has been developed. This system employs a portable reading unit adapted to field conditions, a series of sensors that can be either embedded into concrete or surface mounted on metallic and other existing structures. A software package compares and analyzes the huge data-flow from the system and allows a potentially dangerous slip surface to be identified. This can further enable the prevention of catastrophic roof collapse accidents.

A Framework of the FBG-based monitoring system
Compared with traditional monitoring equipment, the developed monitoring system of optical fibres and CRLD (constant resistance and large deformation) bolts assisted by fiber Bragg grating (FBG) displacement meters has the advantages of providing accurate, reliable, and continuous online monitoring of roof activities in underground coal mining. The system has been successfully implemented at a deep hazardous roadway in Zhuji Coal Mine, China.

Millions of tons of plastic waste could be turned into clean fuels, other products
The United Nations estimates that more than 8 million tons of plastics flow into the oceans each year. A new chemical conversion process could transform the world's polyolefin waste, a form of plastic, into useful products, such as clean fuels and other items.

The conversion process incorporates selective extraction and hydrothermal liquefaction. Once the plastic is converted into naphtha, it can be used as a feedstock for other chemicals or further separated into specialty solvents or other products. The clean fuels derived from the polyolefin waste generated each year can satisfy 4 percent of the annual demand for gasoline or diesel fuels.

Linda Wang, Professor in the Davidson School of Chemical Engineering at Purdue University and leader of the research team developing this technology said, "Our conversion technology has the potential to boost the profits of the recycling industry and shrink the world's plastic waste stock."

AntBot: The first walking robot that moves without GPS
AntBot, the brand-new robot designed by CNRS and Aix-Marseille University (AMU) researchers at ISM, copies the desert ants' exceptional navigation capacities. It is equipped with an optical compass used to determine its heading by means of polarized light, and by an optical movement sensor directed to the sun to measure the distance covered.

Armed with this information, AntBot has been shown to be able, like the desert ants, to explore its environment and to return on its own to its base, with precision of up to 1 cm after having covered a total distance of 14 meters. Weighing only 2.3 kg, this robot has six feet for increased mobility, allowing it to move in complex environments, precisely where deploying wheeled robots and drones can be complicated (disaster areas, rugged terrain, exploration of extraterrestrial soils, etc.).
Using the compass, AntBot measures its heading with 0.4° precision in clear or cloudy weather. This compass is composed of only two pixels topped by two polarized filters that turn to be equivalent to an optical sensor composed of two rows of 374 pixels. The navigation precision achieved with minimalist sensors proves that bio-inspired robotics has immense capacity for innovation.
