Flying courier drone can drive up to your door

Delivery drones have more than a few challenges, not the least of which is dropping off the package in a convenient place. Do you really want to head out to your yard to collect a box? You might not have to. Advanced Tactics has successfully tested delivery with a drone, the Panther sUAS Air/Ground Robot, that can both fly and drive up to your door. When it's too dangerous or costly to travel by air, the machine just has to touch down and wheel its way to its destination. It promises more considerate (not to mention less theft-prone) shipping to homes and offices, and it could also lead to faster deliveries in areas where no one transportation method is particularly speedy.
