1, material: colored mud, round hard paper shell, transparent plastic chip core of cake box (stiff molding), acrylic pigment, torsion bar.
Steps:
2, making a hat: make a hat brim with a round cardboard shell, and the size can be adjusted as needed. Then roll the cardboard paper into a cylinder to make the main part of the hat, and stick it with the brim with hot melt adhesive.
3. Coloring: Coloring the hat with acrylic pigment can draw the starry sky effect and increase the interest.
4, making paper tube rocket modeling: paper tubes with different lengths are rolled out with hard cardboard paper, and then the shape of the rocket head is made. The paper tube and the rocket head are bonded together with hot melt adhesive sticks to form a complete rocket shape.
5. Manufacture of the rocket and star shape of the torsion bar: cut out the corresponding shape with a hard paper shell, then wrap the torsion bar around it and fix it with a glue gun.
6. Making the Earth and Planets: Mix colored mud with different colors, draw them and knead them into a ball, and the shapes of the Earth and Planets can be made. Be careful not to let the colored mud fully blend and mix colors. As long as you draw two or three times properly, you can get different lines of the sphere. Wait for the colored mud to dry before fixing it to avoid the ball deformation.
7. Decoration: If you want to suspend the sphere, you can use iron wire to pass through the sphere to suspend it. Then use cotton or silk cotton to make clouds in the pillow core for decoration.
8. Cut space figures: You can use your own space figure paintings or materials found online to cut them.
Application of space cap;
1, which is used to provide EEG signal acquisition. In the brain-computer interaction experiment, astronauts need to wear EEG caps in order to collect scalp EEG signals. This signal can be used to control external devices, such as robot arms. By collecting and analyzing EEG signals, we can understand the astronauts' intentions and further enhance the interaction ability between people and machines.
2. The space cap also plays a key role in the experiment of sports imagination. In the experiment, if the astronaut imagines the movement of his left hand, the EEG cap will collect relevant EEG signals and transmit them to the mechanical arm. In this way, astronauts can control the robotic arm to perform tasks through simple imagination. This technology is expected to provide disabled people with a more convenient way of operation in the future and help them better interact with the external environment.
3. The space cap is also a key component of the extravehicular spacesuit. It can not only provide safety protection for astronauts, but also ensure various practical operations and visual effects. The special design of extravehicular spacesuit cap can 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 operation and visual functions.
4. The space cap has other important functions. For example, it can help regulate the body temperature of astronauts and maintain a comfortable working environment. The material of the hat also has certain anti-radiation and anti-static properties, which helps to protect astronauts from cosmic radiation and static electricity.
