The device has a design which allows it to move without getting stuck on power cords and other stray objects.
This helps to prevent the device from entering a particular area. Signals transmitted from floor stands tell the device to stop when it reaches the edge of a room or a predetermined line.
The device has a sensor that detects the edge of stairs or other changes in floor level, so it can move away from potential falls. This prevents damage to itself or anything in your home.
Allows you to program the device to begin at a convenient time.
The device sees an approaching obstacle, e.g. furniture or a vase, and slows down to prevent itself from bumping in it.
A gyroscope is a sensor that tracks the orientation of a device, more specifically by measuring the angular rotational velocity. Initially, they were built using a spinning rotor to detect changes in orientation, like twisting or rotation.
