Autonomous shopping concept intends to bring brick-and-mortar and internet shopping into a unified and integrated retail experience. The grab-and-go smart shopping carts promote cashier-free automatic check-out eliminating wait in lines. TechSpot's contributing writer, Cohen Coberly, says, 'While it seemed like brick-and-mortar retail would be all but killed off following the explosive rise of online shopping, what we're instead seeing throughout the US is not death, but evolution.' According to a 2018 survey by RIS News, 'The leading new shopping option wanted by consumers was "grab-and-go" technology (in which customers can self-checkout using their smartphones). 59% said they'd like to use this, and 9% had used it.' In a global survey of 2250 internet users conducted by iVend Retail and AYTM Market Research, 'Roughly 1/3rd of respondents said they would like to make automatic payments using digital shopping carts.' Caper is a smart shopping cart startup. Josh Constine, technology journalist and editor-at-large for TechCrunch, reports, 'The startup makes a shopping cart with a built-in barcode scanner and credit card swiper, but it's finalizing the technology to automatically scan items you drop in thanks to three image recognition cameras and a weight sensor. The company claims people already buy 18% more per visit after stores are equipped with its carts.' Linden Gao, co-founder and CEO of Caper, says, 'It doesn't make sense that you can order a cab with your phone or go book a hotel with your phone, but you can't use your phone to make a payment and leave the store. You still have to stand in line.' The current Caper cart involves scanning an item's barcode and then throwing it into the cart. Brittany Roston, senior editor and contributor at SlashGear, reports, 'The smarter version will eliminate the barcode part, making it possible to simply put the items in the cart while the built-in tech recognizes what they are.' Chris Albrecht, managing editor at The Spoon, also reports, 'The future iterations, already in the works, will remove the barcode and will use a combination of computer vision and built-in weight scales to determine purchases. The customer completes shopping, and pays on the built-in screen.' The concept of scanless carts involves deep learning and machine vision. Cameras are mounted in the cart. The screen on the cart gives the shopper different kinds of information - store map, item locator, promotions, deals etc. It recommends items based on contents already in the basket. Read on...

Team of researchers from University of Michigan at Ann Arbor (Prof. Timothy F. Scott, Prof. Mark A. Burns, Martin P. De Beer, Harry L. Van Der Laan, Megan A. Cole, Riley J. Whelan) have developed a new approach to 3D printing that lifts complex shapes from a vat of liquid at up to 100 times faster than conventional 3D printing processes. 3D printing could by highly beneficial for small manufacturing jobs without the need for a costly mold. But the usual 3D printing approach of building up plastic filaments layer by layer hasn't been usable in that aspect. Prof. Scott says, 'Using conventional approaches, that's not really attainable unless you have hundreds of machines.' The U. of Michigan innovative 3D printing method solidifies the liquid resin using two lights to control where the resin hardens - and where it stays fluid. This enables solidification of the resin in more sophisticated patterns. The process can make a 3D bas-relief in a single shot rather than in a series of 1D lines or 2D cross-sections. The printing demonstrations from this approach include a lattice, a toy boat and a block M. Prof. Burns says, 'It's one of the first true 3D printers ever made.' By creating a relatively large region where no solidification occurs, thicker resins - potentially with strengthening powder additives - can be used to produce more durable objects. The method also bests the structural integrity of filament 3D printing, as those objects have weak points at the interfaces between layers. Prof. Scott adds, 'You can get much tougher, much more wear-resistant materials.' The research paper, 'Rapid, continuous additive manufacturing by volumetric polymerization inhibition patterning', is to be published in Science Advances. Read on...
