a body member having one surface onto which the sensors are mounted;
a case that is fixed to the body member, the case comprising:
an inner space in which the body member is disposed; and
an opening defined in one surface thereof exposing the inner space, the sensors being exposed through the opening; and

a cover configured to open and close the opening of the case,
wherein, the sensors are configured to be detached from the body member through the opening of the case with the case fixed to the body member,
wherein the sensors comprise:
a camera sensor disposed in the inner space of the case facing the opening, the camera sensor configured to recognize an object in a visible region;
an infrared sensor disposed in the inner space of the case facing the opening, the infrared sensor being configured to recognize an object in an infrared region;
a lidar sensor disposed in the inner space of the case facing the opening, the lidar sensor configured to map a distance from an object by emitting an optical pulse and detecting a carrier signal reflected from the object; and
a radar sensor disposed in the inner space of the case facing the opening, the radar sensor configured to map a distance from the object by emitting electromagnetic waves and detecting the carrier signal reflected from the object,

wherein each of the camera sensor, the infrared sensor, the lidar sensor, and the radar sensor comprises a male screw thread disposed on an outer circumferential surface of one distal end,
wherein the body member comprises a mounting groove, the mounting groove comprising a female screw thread disposed on an inner circumferential surface of the mounting groove, and
wherein each of the camera sensor, the infrared sensor, the lidar sensor, and the radar sensor is coupled to the body member by screw-coupling the male screw thread to the female screw thread.

2. The sensor-cluster apparatus of claim 1 , wherein the cover comprises a material through which infrared rays, visible light, optical pulses, and electromagnetic waves are transmittable.

3. A sensor-cluster apparatus, comprising:
sensors configured to detect and collect external environment information, the sensors comprising one or more kinds of sensors;
a body member having one surface onto which the sensors are mounted;
a case that is fixed to the body member, the case comprising:
an inner space in which the body member is disposed; and
an opening defined in one surface thereof exposing the inner space, the sensors being exposed through the opening; and

a cover configured to open and close the opening of the case,
wherein, the sensors are configured to be detached from the body member through the opening of the case with the case fixed to the body member,
wherein the sensors comprise:
a camera sensor disposed in the inner space of the case facing the opening, the camera sensor configured to recognize an object in a visible region;
an infrared sensor disposed in the inner space of the case facing the opening, the infrared sensor being configured to recognize an object in an infrared region;
a lidar sensor disposed in the inner space of the case facing the opening, the lidar sensor configured to map a distance from an object by emitting an optical pulse and detecting a carrier signal reflected from the object; and
a radar sensor disposed in the inner space of the case facing the opening, the radar sensor configured to map a distance from the object by emitting electromagnetic waves and detecting the carrier signal reflected from the object,

wherein each of the camera sensor, the infrared sensor, the lidar sensor, and the radar sensor comprises a flange disposed between both distal ends, the flange having increased diameter,
wherein one distal end of each of the camera sensor, the infrared sensor, the lidar sensor, and the radar sensor is inserted into a mounting groove defined in the body member, and
wherein the sensor-cluster apparatus further comprises a coupling bolt coupled to the body member passing through the flange and fixed to the body member.

4. The sensor-cluster apparatus of claim 3 , wherein the radar sensor and the camera sensor are disposed at a center of the body member, the camera sensor being disposed above the radar sensor, and
wherein the lidar sensor and the infrared sensor are disposed at respective sides of the body member with the camera sensor and the radar sensor disposed therebetween, the infrared sensor being disposed above the lidar sensor.

5. The sensor-cluster apparatus of claim 4 , wherein the radar sensor and the camera sensor are disposed facing perpendicular to a surface of the body member,
the infrared sensor is disposed facing angled at an angle in the range of equal to or greater than 20 degrees to equal to or less than 70 degrees from the camera sensor, and
the lidar sensor is disposed facing angled at an angle in the range of equal to or greater than 20 degrees to equal to or less than 70 degrees from the radar sensor.

6. A sensor-cluster apparatus, comprising:
sensors configured to detect and collect external environment information, the sensors comprising one or more kinds of sensors;
