Royal Mail Is Doing the Right Thing With Drone Delivery

Drones are actually the best way of delivering mail to far-flung islands

A large drone with twin propellers stands idle on a remote airport runway as a postal worker walks towards it with two large mail bags

Eight-ish years ago, back when drone delivery was more hype than airborne reality (even more so than it is now), DHL tested a fully autonomous delivery service that relied on drones to deliver packages to an island 12 kilometers off Germany’s North Sea coast. The other alternative for getting parcels to the island was a ferry. But because the ferry didn’t run every day, the drones filled the scheduling gaps so residents of the island could get important packages without having to wait.

“To the extent that it is technically feasible and economically sensible,” DHL said at the time, “the use of [drones] to deliver urgently needed goods to thinly populated or remote areas or in emergencies is an interesting option for the future.” We’ve seen Zipline have success with this approach; now, drones are becoming affordable and reliable enough that they’re starting to make sense for use cases that are slightly less urgent than blood and medication deliveries. Now, thinly populated or remote areas can benefit from drones even if they aren’t having an emergency. Case in point: The United Kingdom’s Royal Mail has announced plans to establish more than 50 new postal drone routes over the next three years.

A black hard case contains a white device with beige layers with wires connecting to electronics on the top of the interior of the case.

The unit weighs less than 10 kilograms, does not require the use of filters, and can be powered by a small, portable solar panel.

Reduce EMI and EMC Issues with Engineering Simulation Software

Electronic components and systems exist today in nearly all consumer and industrial products. A major design consideration in all electronics is electromagnetic interference (EMI) and compatibility (EMC). EMI and EMC issues are complex. They can be hard to detect and can be taxing to a design. With the use of engineering simulation software, design engineers can mitigate issues before entering the prototype testing phase. Avoiding the test-retest cycle with simulation can help save time and money all while delivering robust and reliable products.
