Many of the world's robots toil away inside industrial factories. But one project in Japan is testing whether they can efficiently deliver packages in offices.
Officials say these "white collar" devices might help ease a serious labor shortage and keep humans safely distanced amid the pandemic.
Major real-estate company Mori Trust and a Tokyo-based IT venture firm are conducting the trial in an office tower.
First, a delivery person enters data about a package's recipient and then leaves it in a box.
A robotic arm hands the parcel to the robot that carries it to the right office.
Going through doors and riding elevators aren't a problem, as the robots are linked to the facilities.
The officials say they would like to put the technology into practical use by the end of this year.
