Their creators imagined these autonomous robots to have the size (and cargo capacity) of a shopping basket. The device is meant to carry food, shopping bags, or other small packages from a store or restaurant to a customer that lives relatively nearby.
Instead of using a delivery agent with a vehicle, and generating CO2 emissions from its operation, these robots would operate on the sidewalk in silence and handle what is known as "last-mile delivery."
Before preparing tin foil hats and announcing the imminent uprising of robot overlords, you should know that these devices still need humans to be refilled with packages when they are sent for delivery.
Moreover, they still require maintenance, as well as charging, and those are tasks that only humans are "equipped" to handle. For now, at least.
As a video posted on Imgur has shown, a snow day might delay a delivery significantly, as seven robots were spotted by a user who goes by the name "justabutternut" and posted online. The vehicles seem to have gotten stuck in the snow, and all seven robots were following the same route.
Hopefully, we will see a statement from the Estonian company that will explain what went wrong. If you were to ask us, it would look like a matter of grip. With different wheels, the company might avoid similar situations going forward.
