The robot, created by a startup called Starship Technologies in 2014, is basically a cooler on wheels。s job was to monitor how it handled various grounds, field ments from the public, and press the off switch if necessary. He said, People would also ask if it could deliver beer. It couldn39。 Broadly speaking, jobs of caring for robots fall under the umbrella of careers in automation, which include maintenance, engineering and programming. The demand for people with this skill set is considerable, with 20 million to 50 million new jobs to be expected in this category by 2030, according to the Mckinsey Global Institute. In the year that ended in June 2018, had almost three times the number of positions on the recruitment mittee that ended in June 2016.s campus while it delivered Red bull and other drinks to students. To retrieve (檢索) orders, the app encourages students to give the robot a wave。s digital eyes will roll depending on its mood. Rodriguez, who heads business development for the startup, was tasked, early on, with monitoring the KiwiBot for problems – even carrying it, should the motors fail. Since April 2018, though, the KiwiBot has largely been left unattended, and the majority of human interactions involve technical checks and loading food into the robot. To eliminate the boring work, the team is developing a restaurant robot to collect and load orders – which could happen in 2020. However, Rodriguez assured me that his staff won39。 Mckinsey estimates that millions of jobs globally could be lost to automation by 2030. A huge number of jobs will be produced as autonomous vehicles are released into the environment, Ramsey said.
