1. A kit for generating a distress signal based on solar energy, the kit comprising:
a base unit that includes a base plate, a long-distance communication module coupled to one side of the base plate, a GPS module, at least one processor and a battery; and
a plurality of arm units that are spaced from one another and arranged around the periphery of the base plate, and are connected to the base plate through a first hinge;
wherein each arm unit includes:
a first arm plate that is connected to the base plate at one end thereof through the first hinge, and can rotate around a folded portion of the first hinge as a rotation axis in a clockwise or counter-clockwise direction;
a first solar module and a first light emitting module, which are attached to one side of the first arm plate facing the rotation direction in a clockwise direction;
a second arm plate that is connected to the other end opposite to the one end of the first arm plate through a second hinge, and can rotate around a folded portion of the second hinge as a rotation axis in a clockwise or counter-clockwise direction; and
a second solar module and a second light emitting module, which are attached to one side of the second arm plate facing the rotation direction in a counter-clockwise direction;
wherein the at least one processor controls the first solar module and the second solar module to generate electric energy using the received light energy, and then to store the generated electric energy in the battery, and also controls the first light emitting module and the second light emitting module to emit light using the electric energy stored in the battery;
wherein, if the kit is in a first state, a distress signal is sent by controlling the long-distance communication module;
wherein the first hinge is configured to be folded or unfolded between a first preset maximum angle and a first preset minimum angle; and
the second hinge is configured to be folded or unfolded between a second present maximum angle and a second present minimum angle;
wherein the first state is a state in which:
the first hinge is unfolded at the first maximum angle and thus the first arm plate extends in a radial direction of the base plate; and
the second hinge is unfolded at an angle between the second maximum angle and the second minimum angle and thus the second arm plate rotates in a counter-clockwise direction to a folded portion of the second hinge as a rotation axis;
wherein, when the distress signal is received from another kit of a person in need of rescue, which is different from the kit, the at least one processor determines a direction and a distance using a first location of the person included in the distress signal and a second location determined by the GPS module; and
the at least one processor controls the first light emitting module and the second light emitting module included in an arm unit corresponding to the above direction among all of the arm units to emit light in a pattern corresponding to distress type included in the distress signal and the above distance.
