In their latest adventure in derring-do, a team from the National University of Singapore (NUS) Faculty of Engineering has developed and flown Asia’s first fully solar-powered quadcopter drone.  A large framework holds the solar cells, which are the sole means of powering the craft’s four motors.  Developers have flown the big square above 10 meters in test flights and achieved controllable flight without the use of batteries. Frogworks Snowstorm This is just the latest in a series of aeronautical exploits by NUS students.  In late 2015, they unveiled their Frogworks Snowstorm, a 24-rotor person carrier powered by 2.2 kilowatt (2.94 horsepower) motors driving 76-centimeter (30-inch) propellers. New Asia reported that, “At the London edition of technology event Founders Forum this …

A Snowstorm in Singapore

Having worked on a three-week project in Singapore 10 years ago, your editor became accustomed to the daily temperatures approaching 100 degrees Fahrenheit, and evenings at a temperate 80 degrees (which some locals described as a “cold snap”).  It makes one wonder where the name “Snowstorm” came from when students at the National University of Singapore worked two semesters to bring their mult-rotor recreational flying vehicle to fruition.  An eight-person student team working as “FrogWorks” started with a 1/6th-scale model, then scaled that up to something that could carry and be controlled by a single pilot. FrogWorks is a collaborative effort between NUS Faculty of Engineering’s Design-Centric Program (DCP) and the University Scholars Program (USP).  According to NUS, “FrogWorks engages …
