The manual tutorial for making aerospace hats is as follows:

1. Materials: colored clay, round cardboard shell, transparent plastic core from ordinary cake boxes (stiff, better for shaping) ), acrylic paint, twist stick.

Steps:

2. Make a hat: Use a round cardboard shell to make the brim, and the size can be adjusted as needed. Then roll the hard cardboard into a cylindrical shape to make the main part of the hat, and use a hot melt glue stick to stick it to the brim.

3. Coloring: Use acrylic paint to color the hat to create a starry sky effect and add interest.

4. Make a paper tube rocket shape: Use hard cardboard to roll out paper tubes of different lengths, and then make a rocket head shape. Use a hot glue stick to stick the paper tube and rocket head together to form a complete rocket shape.

5. Make the rocket and star shapes of the twist stick: Use a cardboard shell to cut out the corresponding shapes, then wrap the twist stick around it and fix it with a glue gun.

6. Make the earth and planets: Use colored clay of different colors to mix together, draw and roll into a ball to make the shape of the earth and planets. Be careful not to allow the colored clay to fully blend into the mixed colors. Just draw it appropriately two or three times to get different textures on the sphere. Wait for the colored clay to dry before fixing it to prevent the sphere from deforming.

7. Decoration: If you want to make the sphere suspended, you can use wire to pass through the sphere to make it suspended. Then use cotton or silk cotton from the pillow core to make clouds for decoration.

8. Cut out space characters: You can use your own space character drawings or materials found online for cutting.

Applications of aerospace hats:

1. Used to collect EEG signals. In brain-computer interaction experiments, astronauts need to wear EEG caps to collect EEG signals from the scalp. This signal can be used to control external devices such as robot arms. By collecting and analyzing EEG signals, the astronauts’ intentions can be understood and the interaction between humans and machines can be further enhanced.

2. The aerospace hat also plays a key role in the motor imagination experiment. In the experiment, if the astronaut imagines the movement of his left hand, the EEG cap will collect relevant EEG signals and transmit these signals to the robot arm. In this way, astronauts can control the robot arm to perform tasks through simple imagination. This technology is expected to provide disabled people with more convenient operations in the future and help them better interact with the external environment.

3. The space hat is also a key component of the extravehicular space suit. It not only provides safety protection for astronauts, but also ensures various practical operations and visual effects. The extravehicular spacesuit hood is specially designed to protect astronauts from environmental factors such as vacuum, pressure and temperature. At the same time, the structure of the hat also ensures the safety of the astronaut's head and face, and provides necessary operational and visual functions.

4. The aerospace hat also has some other important functions. For example, it can help regulate astronauts' body temperature and maintain a comfortable working environment. The material of the hat also has certain anti-radiation and anti-static properties, helping to protect astronauts from the hazards of cosmic radiation and static electricity.
