He does this, by the way, with the help of six “legs”
South Korean developers have created a unique robotic case that can independently charge a smartphone. So, the cover itself is equipped with “legs”, which allows it to move in the required direction.
It is known that the width of the cover almost corresponds to a smartphone, while in length it exceeds it since it is its upper part that is equipped with two motors and other details. The device has six “legs”, three on each side. Interestingly, at the moment, the robot cover moves under the user’s control, while the developers plan to add an autonomous control system. The weight of the device, in turn, is no more than 82 grams.
