An article in the website geek.com (http://www.geek.com/news/walmart-is-turning-its-shopping-carts-into-robots-that-follow-you-1658786/) describes a partnership between Walmart and Five element Robotics to assist Walmart shoppers using a personal robot. The goal is to have the robot gather things in the shopper’s shopping list and freeing the shopper’s hands. Will such a focus on the shopping list decrease impulse buys by shoppers ? How can the robots be integrated with retailer promotions to get shoppers interested ? Will shoppers even be interested in going to the store if they just need to follow the robot ? Can Walmart use this approach to compete against Amazon ?
