Are you in a hurry when playing with theservo? Do you always feel like something is missing?
Many friends who have just started playing with robots or smart gadgets will encounter a common trouble: wanting to control severalservos at the same time and make them move in a coordinated manner. The motherboard I'm using probably doesn't have enough PWM ports, and writing code to handle timing synchronization is overwhelming. As soon as the program becomes complicated, theservostarts to vibrate and the movements become unsmooth, which makes people crazy. In fact, you don't need a more complex motherboard, but a professional "little butler" for the servo - such as the Micro 6-channel servo controller. Although it is small, it can liberate you from those cumbersome basic controls, allowing you to focus on more interesting ideas.
Directly controlling the servo with a microcontroller sounds straightforward, but this task actually takes up quite a lot of resources. The servo needs an accurate pulse of about 20ms, and the microcontroller CPU has to keep this in mind. Once it is interrupted by other sensor reading or data processing, and the pulse is inaccurate, the servo will shake. Not to mention that if you want to control 6 servos at the same time to perform compound actions, it is a huge burden on the microcontroller. Giving this job to such a professional controller is equivalent to hiring a professional assistant. Your main control brain can handle more advanced logical operations, and the overall system efficiency is higher.
Even though it is smaller than a USB flash drive, controlling 6 servos is a piece of cake for it. The 6-channel version is specifically designed for this. It has a built-in high-performance processor that can independently and simultaneously generate 6 accurate PWM signals. This means that you can have 6 servos start operating at different speeds and angles at the same time, without affecting each other at all. Whether it is the six legs of a hexapod robot or the six joints of a robotic arm, it can be held firmly and the movements can be completed in one go. You no longer have to worry about the "ghostly" shaking caused by being unable to control it.
If you want the servo to perform a set of smooth "dance steps", programming may dissuade many people. But it provides another way of thinking: think of it as a player that can "remember" actions. You can use their free graphical software on your computer to intuitively adjust the angle of each servo by dragging the slider with your mouse. Set the key postures frame by frame, and then set the transition time, and it can calculate the intermediate process by itself, forming an extremely smooth continuous action. You can even save it as a script and run it offline without writing a single line of code.
If you still like to write code, or need it to work with sensors, that's totally fine. It supports three control modes: USB virtual serial port, TTL serial port, and internal script. This means you can use a simple serial port command, such as "Turn servo number 1 to the 1200 microsecond position" and it will execute immediately. Even more powerful is its internal script function. You can burn a complex, multi-server coordinated action sequence into the board in advance, and then give it a trigger signal through just one line, and it can complete the entire "performance" by itself, which greatly simplifies the design of the host computer program.
When choosing this type of product, there are several hard indicators that you must pay attention to. The first is the resolution, which can achieve a pulse accuracy of 0.25 microseconds, which means that the angle control of the servo is very delicate and almost noise-free. The second is the update rate, which supports adjustment and can reach a maximum of 333Hz, which is suitable for fast-responding digital servos. The third is the input voltage range. It comes with a voltage regulator that can input a wide voltage from 5V to 16V. Whether it is using two lithium batteries or four dry batteries, it can be flexibly adapted. These solid parameters are the basis for ensuring control quality, and they are not comparable to those simple PWM generators.
With this compact controller, your creative boundaries suddenly open up. ️Makea bionic robot: It is perfect to control the coordinated walking of a six-legged or four-legged robot. ️DIY robotic arm: Precisely control each joint to complete grabbing and carrying actions. ️Makeautomatic props: such as dolls that can open and close automatically, and simulated animal models that can turn their heads. ️Asa sensor actuator: Connect it to the Raspberry Pi and let it be responsible for all servos, while the Raspberry Pi concentrates on image recognition. Its application scenarios are far more than you think, and each project can be made more professional and stable.
After reading this, are you feeling itchy and want to use it to upgrade your projects quickly? If you plan to use it to make a small robot, do you think the first problem to overcome is to make it stand up first, or to make it learn to take two steps first? Welcome to share your thoughts in the comment area, let’s discuss together, and don’t forget to like and share so that more friends who are tortured by the servo can see this solution.
