A crawler robot, comprising:

• a frame;
• a humidity sensor installed on the frame;
• a plurality of wheels located on at least two sides of the frame;
• a camera;
• first and second sets of one or more motors;
• and
• a processor;
• wherein the frame is configured to pass through a hole into an interior space of a balcony;
• wherein the processor of the crawler robot is configured to:
• receive a first plurality of signals from a processor of an electronic device to rotate the plurality wheels of the crawler robot, or to move the plurality wheels of the crawler robot to left or right, to navigate the crawler robot inside the interior space of the balcony;
• send a second plurality of signals to the first set of motors in response to receiving the first plurality of signals;
• receive a third plurality of signals from the processor of the electronic device to move the camera;
• and
• send a fourth plurality of signals to the second set of motors in response to receiving the third plurality of signals;
• wherein the first set of motors are configured to receive the second plurality of signals from the processor of the crawler robot and rotate the plurality wheels of the crawler robot, or move the plurality wheels of the crawler robot to left or right, to navigate the crawler robot inside the interior space of the balcony;
• wherein the second set of motors are configured to:
• receive the fourth plurality of signals from the processor of the crawler robot;
• and
• move the camera in response to receiving the fourth plurality of signals;
• and
• wherein the humidity sensor is configured to:
• make a plurality of humidity measurements from the inside of the interior space of the balcony;
• and
• send the plurality of humidity measurements to the processor of the electronic device.
