Lyft, the second largest ride-hailing service in the U.S., once helped disrupt the taxi industry. Now, the company is working hard to avoid being disrupted itself as self-driving cars turn from sci-fi into reality. According to Taggart Matthiesen, vice president of product at Lyft's Autonomous Group, the company has assigned around 400 of its engineers to work on two distinct self-driving initiatives. One is the "open platform" where Lyft connects passengers with semi-autonomous vehicles created by its partners, including Aptiv in Las Vegas and Alphabet's Waymo in Chandler, Arizona. The other is Lyft's effort to create its own self-driving systems, work that it does primarily at Level 5, its sizable lab in an unassuming office park in Palo Alto, Calif.

Instead of heavy textbooks, your school backpack could one day carry equipment that instantly maps out your environment in 3D. The Air Force recently announced that a portable laser backpack for 3D mapping has been developed by researchers at the University of California at Berkeley. While bulky, the prototype backpack has already been used to map out two stories of Cory Hall, an electrical engineering building on the UC Berkeley campus. It rapidly gathers data while the user walks around inside a building. The information can be put together into a detailed, photo-realistic 3D map.
