It is no secret that many companies are using robots to automate operations and become more efficient. DHL happens to be using EffiBOT for collaborative automated order picking. It is a fully automated trolley that follows pickers through the warehouse and reduces their physical workload.
These robots are designed to work safely with and around people. They can drop off the orders automatically once fully loaded. EffiBOT has sensors to avoid obstacles and collisions. DHL has more on these robots.
