Called the "Queen of Carts," a new, safer shopping cart has won the ninth annual National Engineering Design Challenge. JETS--the Junior Engineering Technical Society--sponsors the high school competition. JETS this year asked students nationwide to design and build a shopping cart that would not tip over and injure young children. Winning the finals held at George Washington University (Washington, DC) was a team from West Perry High School (Elliottsburg, PA). The team's invention, a six-wheel cart made of steel with nylon webbing around the sides, includes a nylon child seat in the front. The Queen of Carts' two center wheels serve as stabilizing wheels and the pivot point. Thus, the cart can turn from either front or back around the center pivot wheels. The new design turns 360 degrees in its own length, while the standard cart, with pivot point in the back and turning wheels in the front, takes twice the cart's length to circle.
Being in an incubator can be analogous to shopping in a “big box retailer.” You can find many things you need under one roof along with moral support to sustain and move your startup to a successful launch.
Scientists at four major universities in Europe have released a joint paper describing the use of light to put active materials into motion and to control that motion, producing lifelike mechanisms that may or may not contain living organisms, but can produce useful work.
