An anonymous reader writes from a report via Bloomberg: Bloomberg reports Walmart is working with a robotics company to develop a shopping cart that helps customers find items on their lists and saves them from pushing a heavy cart through a sprawling store and parking lot. The carts are a way for brick-and-mortar stores to stay relevant in the convenience factor to match the likes of Amazon and other online retailers, says founder and chief executive officer of Five Elements Robotics Wendy Roberts. She said on Tuesday at the Bloomberg Technology Conference 2016 that her company was working with the "world's largest retailer" on such a shopping cart. In 2014, Five Elements Robotics introduced Budgee, a personal robot that can follow its user around inside and outdoors and carry things. The robot costs $1,400 and is helpful for people with disabilities, says Roberts.
