답답해서 내가 만들고 내가 리뷰한다! 모션 컨트롤 카메라 로봇 비하인드 스토리

Hello. I’m mingul. It’s been a long time since I said hello. A lot of people liked the camera robot making video. So, I made this video that I didn’t plan on. If you haven’t seen the last video, I recommend you watch the video first through the link at the top. In this video, we’re going to talk about the equipment review and production episode. 3 months to manufacture. $9000 for materials and parts. This is the biggest thing I’ve ever made. Almost all of the parts are aluminum and it has been cnc milling and lathe machining. Some of the parts are 3D printed. The FDM 3D output was tested in its own very scientific way The result is a lack of durability and stiffness, all replaced with aluminum. I used a type ‘L-shape’ aluminum profile as a x and y axis rail. The biggest reason for applying the profile was because of the production cost. When I first planned it, when I used all the parts that I needed to operate as off-the-shelf, I got an estimate of nearly $34,000 for the processing materials and parts alone. It was an amount I couldn’t afford. So one of the most intense concerns in the
production process was to down production costs. I designed the x, y axis using the profile. I applied a variety of door wheels where movement was needed. For the profile, it was cheap and easy to get. Off-the-shelf rail like LM-guide is the maximum size of 3m unless it’s custom-made. In contrast, profiles can be easily purchased over 6m in length. It’s a cheap part, not to mention a door wheel. From large factory doors to sliding doors of furniture, there are various door wheels used in different environments. If you have any idea what kind of door wheels are available, you may occasionally use them to make them useful. The most effective part of this replacement was the bearing used on the PAN axis. As for bearings, as they start to grow in size, the price increases exponentially. But I needed a drive component about 350mm in diameter to make the entire Z-axis turn stably. So I was looking for a replacement product in many ways, and I found that if you go to a Chinese restaurant, there’s a rotating table to see, right There is a table bearing for a few dollars for furniture used in making such a table. I was able to save a lot of money by applying the table bearing to the PAN axis. However it was not a finely machined part as it was cheap. Because it was made of simple castings, each product had different operating conditions. The operation wasn’t as smooth as I thought. So I bought several and then separated the bones and flesh…. No, I disassembled them and reassembled them in good condition. I cleaned everything in a disassembled state and polished it again. The Z axis to be rotated weighed approximately 80 kg. The load bearing specification for table bearings is 100 kg per piece. Passed a very scientific self-test. But the spec is good, so go double. Now let’s look at the overall structure. The Y-axis located at the top has been carefully fixed on the ceiling. My studio ceiling has sandwich panels. The bolt and nut are fastened through the through hole. It has a total of four tracks in the form of a 7.5m long ladder rails. The 5.5m long X axis rail is suspended on those four tracks. The X- and Y-axes were each able to move using two nema34 motors and chain belts. The PAN axis then used the previously described table bearings, direct-fabricated pulleys, and nema23 stepping motors with timing belts and reducers. Next is the Z axis. The Z-axis was a bit of a struggle because it was difficult to get some resources and examples to reference when designing. It’s my greed. I wanted to maximize the Z-axis stroke. Generally, cameras are used most often at this height. Still, I wanted to write Bird Eye View, and I wanted to shoot while lying on the …. Anyway, the required working distance was about 2.2m. Since the ceiling of the workshop was not so high, the general gantry structure using one rail could not be used. So I designed a three-stage telescopic structure that stretches like a drawer. Telescopic also has a variety of design methods. In my case, I used a slightly modified version of the method in the top link video. The channels introduced in that link are the channels through which the various operating structures are known. If you are interested, please refer to it. I used TM screw to drive up and down. It is cheaper than a ball screw and has a certain frictional force, so it does not flow down when the power is turned off without applying a brake type step motor. Instead, it takes some load. The tilt and roll axes, zoom and focus axes are designed to be plain. There was no suitable off-the-shelf pulley and gear, so I used parts printed on a 3D printer. It is not a largely stressed part, and due to the characteristics of the timing belt, the contact area is large, so the force is dispersed. So it seems to be durable enough to use 3D printer output. Most of the parts related to operation such as the controller, driver, PC, power supply and motor were built in the X-axis, and the length of various wirings was reduced by 1/3 compared to the external installation. Wire lengths are more susceptible to noise as they get longer, so the shorter the process, the higher the stability. You can save money too. Camera monitoring and main unit control are set up in such a movable table. The reason why I can control and monitor it at the desired location is because I used an HDMI wireless transceiver. It can receive video signals wirelessly at a distance of up to 100 meters. Video transmitters, which are often used for commercial video production, are very expensive. Luckily, products that come out of the house also have enough features and performance in indoor environments. The delay is not bad either. I used two sets of radio transceivers. One set used the PC screen and the other for camera monitoring. The controller that controls each motor used DMC-16, a dragon frame controller. As it is an expensive controller that accounts for about one third of the total parts price, it provides various functions. 16 channels, that is, 16 drive shafts can be controlled at the same time. This means that you can make and use accessories for controlling various shooting environments. By simply adding a turntable, you can use it this way, and there are a lot of uses depending on how you use it. It is a controller and software that was originally created to produce stop motion animations, , so it has powerful stop motion creation capabilities. This stop motion production will be discussed in more detail later along with other video content. Along with stop motion, I use live motion recording that I use mainly to make movies with this motion. I haven’t set it up yet, but I can connect the DMX lights, so I can pre-program the various lights. Next to the DMC-16, there are drivers to run the motor with signals from the controller. Next to it is a PC that runs the program and 5V, 12V, and 24V SMPS that power each part. I briefly talked about the overall structure. It’s the most talked about video I’ve ever made. I’m not used to talking in front of the camera and microphone yet. The pronunciation is also twisted. If you look at the last video, it looks like I made it in a hurry, but it’s actually in a hurry. As I made it in a hurry, it took me a lot of time to finish it with a design mistake. One month to design, one month to assemble parts and assemble. It took me about two months to get to this scene, but it seems like it took another month to solve the unexpected problem as I finished it. There were two unexpected problems, one of which was a vibration problem. The other was the problem of wiring. The wiring wasn’t easier than I thought. I thought it would not be a big problem if you hang it properly. It took a lot of time there. Let’s take a look at the trouble shooting process that was in progress. Are you bored? Originally, these videos aren’t fun. There may be a reason why I can’t have fun. I think it’s hard to make these videos fun. So I want to avoid too. Still, I asked you to see more details, so I am shooting like this. Even if it’s not fun, please enjoy it until the end. Let’s keep watching. The problem that was really very difficult was to solve the wiring problem. At first, I would simply use a cable carrier. Naturally, cable bearers should only be folded in one direction according to experience and spec. Even if we tested it scientifically. However, these things became meaningless when the length became longer. So we needed a guide to support the cable carrier because of its weight. The first attempt was to use a cable carrier like a chain to follow a geared supporter. But life is not easy. Failed correctly! give up quickly, and think again. The supporter has to move half the distance the body moves. Using wire and pulley like this like this like this like this..
I had a good idea. Life is not easy. right? The cable carrier is so long that it must be supported in the middle. So I made some additional parts to support the center, and I made some more improvements to the design. In fact, I wouldn’t have thought that I would have suffered if it was over. The process was quite enjoyable so far. But the battle with the cable carrier, who supported the center once more, would end up in the third round, arranging the actual wiring. From this time on, the failures of mentality were broken, and at the end of a long period of work, the physical strength also fell so there seemed to be no power to shoot video. No matter how I look for it, there is no video at that time. Finally, it is completed in the form you see now. Finished by installing the rails that support the top and bottom of the cable carrier. Here is the vibration problem. There were two main causes of vibration. The first of these was due to the chain belt used for the X and Y axes. It is cheaper than the timing belt and can be used to drive the X and Y axes because it can deliver strong force. However, because of its long length, its own weight and the vibration of the motor were added, and despite the tension adjustment with the tensioner, vibration occurred. This problem was reduced by adding chain guides and a separate tensioner. Contrary to worrying about the initial design the X and Y axes did not require large forces to move relative to their load. So I use a light timing belt, and the X-axis is a bit unfortunate because I think I could use only one motor. Another major cause of vibration was the installation environment and design mistakes. It’s a painful point. The installation environment is a ceiling made of sandwich panels as described above. It’s not a solid structure, but it has some elasticity, so when it moves, it’s rumbled. In addition, the rails made of profiles move on the device, and when the load moves, the rails fall. It would have been nice to have a sturdy construction like the truss, but it was a design mistake to rely solely on the rigidity of the profile itself. These problems are not a big problem when making a small piece of equipment, but I think it’s a must check when making a big piece of equipment. So currently, it is impossible to completely solve the vibration problem of X, Y axis, but even though it can be operated faster enough, it is set to operate at a slow speed that almost no vibration occurs. Fortunately, vibration does not occur in any axis other than the X and Y axes. I think I’ll be relocating the workshop in the near future, and I’ll be making some modifications to these parts, and I’d like to build a new, faster and more comfortable design of the MK02 version If the situation is …
