Chapter 112

After the design of the footsteps is completed, what else is there to design? The next step is the design of the torso. Since the torso does not need to exert force or other movements, there is no need to make the torso design too complicated.However, in order to simulate the bending action of humans, it is still necessary to design some devices for the torso of the mecha so that the mecha can bend down like a human being.Since it is only simulating the action of human beings bending over, there is no need to make the design too complicated. It is only necessary to design a gear on the waist of the mech at a specific position, and adjust the position of this gear to drive the movement of the entire waist. , but the position of the gear installation should be designed according to the actual situation, instead of bending over at the belly button like humans.After all, a mecha is just a mecha. The structure of a mecha and a human seems to be the same, but in fact the two structures are fundamentally different. One is made of cells, and the other is made of metal, various alloy materials, and plastics.It is precisely because the material used to make mechas is not cells but metals, various alloys, and various plastic products, which means that the center of gravity of mechas is different from that of humans. It may be different from the center of gravity of human beings bending over, so it is necessary to design the point where the mecha bends down according to the situation of the mecha version 1.0, and put the gear for the mecha to bend over at this point, so that the mecha can be bent. Maintain better stability when bending down, so that the mech will not fall to the ground when bending down.

There is no doubt that it will take a lot of time to measure the selection of this point, because not only the bending part of the mech is to be measured, but also the lower part of the mech, including the legs of the mech and the body of the mech. Part of the torso, and then calculate and estimate the position of the focal point based on the measured data. At this time, design the position of the gear used for the bending of the mecha based on the calculated center of gravity position. This position does not have to be at the focal point. However, it must be ensured that when the gear is in this position, the mecha will not be bent due to this, which is what we often say is not standing firmly.To put it bluntly, this design is to maintain the balance of the mecha, and prevent the mecha from causing imbalance due to the simulation of human body bending.The point where the gear is installed on the mech does not need to coincide with the center of gravity, and even in order to suit the bending action of multiple mechs, one can be properly selected among the measured centers of gravity. This point can be obtained by a certain degree of bending. The center of gravity point, or a point close to all centers of gravity.The design of the gear does not have to be at the center of gravity, as long as the design of the gear can ensure that the mech can still maintain balance when the center of gravity changes.

Not only can the mecha simulate the bending action of a human being, but it can also design different degrees of bending action for the mech. This action can be at an angle of 30 degrees to the vertical line, or at a 45-degree angle to the vertical line. Angle, which can also be an angle of 90 degrees from the vertical.According to the degree of bending of the mecha, record the various data of the mecha, and then continue to calculate the center of gravity, and find an acceptable value in the obtained center of gravity. This value can be used for a 30-degree bending of the mecha without Falling to the ground can also be applied to a 45-degree bend of the mecha without falling to the ground, and it can also be applied to a 90-degree bend of the mech without falling to the ground.The center of gravity is still selected as before, but now the bent state is removed from several angles, so that these angles become a state of the mech bending to different degrees. The setting of this state is mainly for It is convenient for the mecha to control its various commands faster. Just give the mecha a value, and the mecha can calculate how many teeth the bending gear of the mecha should turn according to the value, so that the mecha can complete the bending accurately and quickly action.If there is no design state for the bending action of the mecha, the mecha will reach a certain bending value in one step during the running process, so there will be less simulation state for human body movements.Take bowing as an example, a slight bow is definitely different from a 90-degree bow, and the different degrees of bending of the mech can also make the mech adapt to different movements. For example, bending at 90 degrees can be used to pick up There are things on the ground, and a 30-degree bend can pick up some things on the thighs, and a 45-degree bend can pick up some things on the lower legs or some weapons that are attached to the lower legs. It’s better to have more movements. The more movements the mecha has in the bending state, the more complex movements that humans can perform. However, too many bending states in the design may increase the trouble of the mecha’s operation and the control center. Besides, at present, it is not necessary to design such a complicated design. This Mecha 1.0 is not used for combat, and it does not need to be so complicated at all. As long as it can simply simulate human beings and complete some simple actions, Yes, as for other action simulations, it can be added according to future needs.Because the motion range of the gear is an interval value, it is not fixed, so if you need to add a certain state to the mecha in the future, you can modify the data of the mecha control center to add a certain state. The state is added in, and only by adding this kind of motion state can the operator complete various actions that they need.In the Mecha 2.0 version, or in the Mecha 3.0 version, Liu Yun will release the authority to the user, that is, the person who buys the mecha, so that those who buy the mecha can set the degree of bending of the mecha according to their own needs. In this way, various mech operations can be completed.After all, mechas are mechanical and metal, so they have great advantages over artificial intelligence in nature. The biggest advantage is that mechas are relatively hard. Because they are made of metal, they can replace humans to complete various human tasks. More difficult tasks, such as moving some heavy objects or moving some objects that will harm the human body.Or to complete some activities that are inconvenient for human beings.Since the mecha is just a mechanical structure, it doesn’t matter if it breaks. The big deal is to spend some money to replace the damaged parts. It doesn’t need to be broken once the parts are broken like humans. It is impossible to repair and replace the body’s components.

The mecha obviously does not have such a problem. If the arm of the mecha is broken, you only need to go to Yunfan Technology Company to buy a new arm and replace it. After the arm is replaced, simply modify the wiring inside the mecha You can get a new life in one click.
