MIT team proposes SCR emission control for hybrid aviation turbines; reducing NOx by 95%

Green Car Congress

Now, MIT engineers are proposing using an ammonia-based selective catalytic reduction (SCR) system that could result in an approximately 95% reduction in NO x emissions in exchange for a ~0.5% The trend towards smaller engine cores with smaller mass flow rates in the core stream, presents new opportunities for emissions control.

MIT engineers develop system to help autonomous vehicles see around corners; adapting ShadowCam

Green Car Congress

To improve the safety of autonomous systems, MIT engineers have developed a system that can sense tiny changes in shadows on the ground to determine if there’s a moving object coming around the corner. The big dream is to provide ‘X-ray vision’ of sorts to vehicles moving fast on the streets.

MIT team develops new lane-change algorithm for autonomous cars

Green Car Congress

Most existing lane-change algorithms for autonomous cars have one of two drawbacks: Either they rely on detailed statistical models of the driving environment, which are difficult to assemble and too complex to analyze on the fly; or they’re so simple that they can lead to impractically conservative decisions, such as never changing lanes at all.

MIT researchers build model simulating atmospheric transport of PAHs; how chemicals get to the Arctic

Green Car Congress

MIT researchers have built a model to simulate long-range atmospheric transport of polycyclic aromatic hydrocarbons (PAHs). The model that will be further developed as part of an NSF-funded project to track how chemicals get to remote Arctic environments. Persistent organic pollutants are chemicals of substantial international concern.

JPL ] Cassie Blue showcases its ability to navigate a moving walkway, a common yet challenging scenario in human environments. PAL Robotics’ Kangaroo demonstrates classic “zero-moment point” or ZMP walking, with only one or two engineers tagging along, and neither of them look all that nervous. RAMIEL ] Thanks, Temma! That is all.

Video Friday: Pedipulate

Cars That Think

In order to interact with and manipulate their environments, most legged robots are equipped with a dedicated robot arm, which means additional mass and mechanical complexity compared to standard legged robots. NRL did some interesting stuff with Nexi robots from MIT and made their own videos. Pedipulate ] I learned a new word today!
