Technology and life: starting with solar cars

Chapter 113

Not only can you design some bending movements for the mecha, but you can also design some movements for the mecha to turn around or turn right, and these movements are also realized through gears.The difference between the gear and the wire rope is that the gear is more rigid and can better realize the direction change of the mechanical part in the original position, while the wire rope gives a stretching force to make some parts of the machine move towards the wire rope.Therefore, many mechanical parts can use both gears to transmit kinetic energy and steel wire ropes to transmit kinetic energy, while some parts can only use gears to transmit kinetic energy, and some parts can only use steel wire ropes because it is inconvenient to use gears to transmit kinetic energy. kinetic energy.

If you let the mecha simulate the left or right turn of the human body, you can use the design of the mecha. However, it should be noted that since there is already a gear for the mecha to bend over, it must be well planned in the program. The design of the armor is good, to prevent the gears of the bent mecha from turning left, and the gears of the mecha turning left also start to rotate, which may cause damage to the gears of the mecha, which is not allowed.Therefore, it is necessary to set the priority of the program in the control center, or the priority of the mecha bending gear, the mecha running gear, and the mecha turning right gear.The bending gear of the mecha must be the first priority. First, the control center should detect the current state of the bending gear of the mecha. If the bending gear of the mecha is in its original state, that is, it is not moving, then the mech can be used. The left and right rotation gears of the mecha, if the mecha's bending gear has already moved, the following instructions cannot be continued, that is, the left and right rotation gears of the mecha cannot be moved.Only after the bending gear of the mecha returns to its original position, can the left-turning gear or the right-turning gear of the mech continue to be moved.

As for the left-turning gear of the mech and the right-turning gear of the mech, the left-turning gear of the mech and the right-turning gear of the mech can be combined into one gear, that is to say, one gear is used to realize the left-turning and right-turning of the mech. Turn, but it should be noted that at this time, the gear of the mech should be rotated left and right with an interval value, and the gear of the mecha cannot exceed this interval value, otherwise it may cause damage to the mecha.The left-turning gear of the mecha and the right-turning gear of the mecha can also be separated, which means that the mech uses one gear for running and one gear for the mecha’s right-turning. These two gears can be on the same horizontal plane or on the same plane. On the vertical line, if two gears are on the same vertical line, it is equivalent to being on the spine of the human body.At the same time, pay attention to the design of the abdomen, because the bending of the mech will inevitably cause the metal movement of the mech's abdomen. If the metal on the mecha's abdomen is a fixed gear, turning left will cause the metal of the mecha's abdomen to be stressed and deformed. Considering the problem of metal in the belly of the mecha, during the design, the metal connection method of loose mouth or folding connection can be designed for the belly of the mecha, and the use of fixed metal structure is not allowed.This point is mainly aimed at the part near the gear, because when the mech bends down or turns left or right, it deforms at the position of the gear, so it is not possible to fix the metal near the gear. It must be ensured that the metal near the gear can be rotated or flexibly folded.

As for the left turn and right turn of the mecha, there are not as many states as the mecha bends down. Obviously, the angle of the left turn and right turn of the waist of the human body will not be too large, and it can turn 30 at most. If the angle is too large, a fracture will occur.Therefore, it is not necessary to set a transition state for the left and right turns of the mech from 0 degrees to 30 degrees. For example, the turning angle of 15 degrees is used as the transition state of the left turn. At this time, 0 degrees is The initial state is the state when the mech does not turn left, and 15 degrees is the intermediate state, so 30 degrees is the maximum degree of left turn of the mech.If you give the mech's left turn and right turn a transition state, this transition state will make the mecha have more action states, but there is no doubt that there is not much difference between a 15-degree turn angle and a 30-degree turn angle. It shows that the transition state of 15 degrees is of little significance. There is no need to set an transition state for the left turn of the mecha or the right turn of the mech, and directly give the two states of the left turn and right turn of the mech. That is, one is the stationary state of the mecha, and the other is the angle of 30 degrees relative to the whole body of the mech. These two states are enough, and there is no need to set other states. This can make the mecha It is easier for A to realize a conversion from 0 degrees to 30 degrees, without stopping in the middle, and change from 0 degrees to 30 degrees at one time.

The right turn of the mech is the same as the left turn. Since the angle of the right turn is only 30 degrees at most, there is no need to set any transition state for the mech, just let the mech turn from 0 degrees to 30 degrees, and then turn from 30 degrees Return to 0 degrees.

After talking about the waist turning of the mech, let's talk about the system problem.Since the mech is a new thing, it has never appeared before, so for the mecha, it is necessary to borrow other people's operating system or create an operating system by itself.The functions of the mecha are not very complicated, so for the system design of the mecha, Liu Yun plans to build a system by himself, and use other people's code for the underlying code, but the other code design must be firmly controlled by his company, which is equivalent to The authority of the user, that is, the operator of the mecha, will be withdrawn, and then only the mecha operator will be given a mecha that can be controlled.In addition, the buyer of the mecha has no right to modify any data in the mecha, and cannot make even a slight modification to the data in the mecha. If the user uses various means to attempt to modify the various settings of the mecha It will cause the system to crash, and this kind of crash is not within the scope of the three guarantees. To put it bluntly, it means that users are not allowed to engage in various settings of the mech without permission. There are unknown bugs in the system, so if the buyer of the mecha uses various methods to modify the data of the mecha, Liu Yun, the boss of Yunfan Technology, naturally has the right to crash the system. The modification caused unpredictable errors in the system at critical moments, causing even greater losses to the mech operators.Of course, the fact that data is not allowed to be modified, and all kinds of software cannot be downloaded at will, does not mean that the user does not have any permissions, and it does not mean that Liu Yun is conservative.Buyers of mechs can still download the software needed for various mechas through the platform of Yunfan Technology Company.
