Another country is adopting robotics to assist in postal deliveries — at least on a trial basis.

Brisbane, Australia, is now planning to test after-hour deliveries by an autonomous robot from 6 p.m. to midnight for four weeks starting in mid-November. Essentially a mobile locker, the robot will be accompanied by an Australia Post employee and carry just one parcel at a time, the Courier Mail newspaper reported today.

Prospective customers who are required to register and request a delivery at a time would receive a text message when the robot arrives at their door. The newspaper didn’t identify the robot’s manufacturer.

Last year, the Australia Post was testing $10,000 drones developed by ARI Labs for delivering medication and online retail items, RoboticsTrends reported.

Meanwhile, six-wheeled robots developed by London-based Starship Technologies were tested for mail delivery in Switzerland, England and Washington, D.C., Business Insider reported in 2016.

German postal officials are also testing a delivery robot, according to The Robot Report.

The French-made PostBot is being tested southeast of Bonn during a six-week pilot program. Mail carriers who will initially just use the robots for delivery between the city administrative offices are then expected to employ the technology for conventional delivery routes.
