Have any ideas on how to improve materials engineering for golf carts? They’re a great candidate for a new approach because of skyrocketing accidents. Half of golf cart injuries occur on streets or residential property, and there was a surge in golf cart use when gas prices soared last year. One retiree bought a 20-year-old cart for $300 that can go 20 miles on a 10-hour charge. Twenty-six states allow use of golf carts on local streets. Some states require hazard signs on the back, not unlike the bright signs on the back of Amish buggies. A study by the University of Alabama at Birmingham, said about 1,000 Americans suffer injuries monthly due to golf cart accidents. Male teenagers and people over 80 had the highest injury rates. A study by the Center for Injury Research and Policy at Nationwide Children’s Hospital in Columbus, OH, said annual injury rates for golf carts increased 130 percent in a recent 16-year period.
The company that brought you 3D-printed eyeglasses has launched both an improved clear polymer material for 3D printing optical components and a high-speed, precision, 3D-printing process for making small- and medium-sized batches in a few days.
We've found an amazing variety of robot hands & arms in medicine, space, and service robots, as well as R&D and assembly. Some are based on industrial designs modified for speed or dexterity, while others more closely emulate human movements, as well as human size and shape.
To give engineers a better idea of the range of resins and polymers available as alternatives to other materials, this Technology Roundup presents several articles on engineering plastics that can do the job.
The first photos made with a 3D-printed telescope are here and they're not as fuzzy as you might expect. A team from the University of Sheffield beat NASA to the goal. The photos of the Moon were made with a reflecting telescope that cost the research team £100 to make (about $161 US).
