The Ultimate Maintenance Guide For Diesel Engines

Diesel is preferred over gasoline for three primary reasons: better torque output, long-term durability, and fuel economy. Research shows that diesel engines are typically 20%-35% more fuel efficient than similarly sized gasoline engines, allowing diesel cars to travel greater distances on a single fuel tank.  However, diesel engines require additional care and maintenance to function...

Smart, cheap ‘Joey’ robot could soon help clear blockages in critical pipes underground

Beneath our streets lies a maze of pipes, conduits for water, sewage, and gas. Regular inspection of these pipes for leaks or repair normally requires them to be dug up. The latter is not only onerous and expensive—with an estimated annual cost of 5.5 billion pounds in the UK alone—but causes disruption to traffic as well as a nuisance to people living nearby, not to mention damage to the environment.

Autonomous crawling soft ‘ringbots’ can navigate narrow gaps

Researchers at North Carolina State University have created a ring-shaped soft robot capable of crawling across surfaces when exposed to elevated temperatures or infrared light. The researchers have demonstrated that these "ringbots" are capable of pulling a small payload across the surface—in ambient air or under water, as well as passing through a gap that is narrower than its ring size.
