A technique shortens the time taken to adjust a protection area. An area setting device includes a setting unit that sets a protection area in at least a part of a surrounding environment of a robot to detect an entry of an object, an obtainer that obtains surrounding information about the robot, and a storage prestoring a set value for the protection area and the surrounding information associated with each other. The setting unit sets the protection area based on the set value read from the storage.

The technique allows avoiding collision with an object that is difficult to detect with a radar sensor. A collision avoidance apparatus is an apparatus for an autonomous vehicle including at least one radar sensor for transmitting a radar wave and receiving a reflected wave from an object. The apparatus includes a processor that obtains, from a signal received by the at least one radar sensor, information about a position of the object and information about a reflected power level of the reflected wave, a generator that generates, in response to the reflected power level being higher than or equal to a predetermined value, information about a travel-restricted area being an area adjacent to the object and in which the autonomous vehicle is restricted from traveling, and an output unit that outputs the information about the travel-restricted area.

In a radar apparatus of the present invention, a ghost deciding unit decides whether or not a first condition that a first object candidate and a second object candidate are in the same direction with respect to the transmission/reception unit is satisfied, and then decides whether or not a second condition that, of the first and second object candidates, a reflection power from the first object candidate located farther away from the transmission/reception unit is smaller than a reflection power from the second object candidate located closer to the transmission/reception unit is satisfied. The ghost deciding unit decides that only when the first condition and the second condition are satisfied, the first object candidate is a ghost.
