Walmart is now using robots to help stock shelves at 50 stores across the country.

The robots are helping scan and stock items in stores before the busiest shopping season of the year. The robots are about two-feet-tall and are outfitted with cameras that help them scan aisles and identify missing or mislabeled inventory across the stores. The robots also check for mispriced items, and give the information to employees who fix the issues.
