• AI implications: Engineer's model lays groundwork for machine-learning device

    In what could be a small step for science potentially leading to a breakthrough, an engineer has taken steps toward using nanocrystal networks for artificial intelligence applications.
  • Reliable Perching Makes Fixed-Wing UAVs Much More Useful

    Inspired by birds, S-MAD uses a controlled approach and microspine toes to land on vertical surfaces and take off again
    UAV designs are a perpetual compromise between the ability to fly long distances efficiently with payloads (fixed-wing) and the ability to maneuver, hover, and land easily (rotorcraft). With a very few rather bizarre exceptions, any aircraft that try to offer the best of both worlds end up relatively complicated, inefficient, and expensive. The ideal fantasy UAV would be a
  • Self-Driving Wheelchairs Debut in Hospitals and Airports

    Autonomous vehicles can add a new member to their ranks—the self-driving wheelchair. This summer, two robotic wheelchairs made headlines: one at a Singaporean hospital and another at a Japanese airport.
    The Singapore-MIT Alliance for Research and Technology, or SMART, developed the former, first deployed in Singapore’s Changi General Hospital in September 2016, where it succe
