Dear friend, thank you very much for your support. First, let me declare the value of the goods. Usually, the price you pay is 38~45$ (due to different postage). It contains 8xSG90 servos (US$2 X8 each) and a nodemcu 8266 board (US$3.5), an expansion board (US$3) and 35 3D printed parts (consumable PLA costs US$2.5, each set takes 3 hours ), power battery (US$2.5), USB data cable, DC charging cable (US$2). Printed brochures and packaging boxes (US$1). The shipping fee I set is generally that the buyer bears 50% of the shipping fee, and I will also bear the average shipping fee (US$5) for each order. If there is no refund, I will get a profit of approximately [US$2-3] per set. The reason for the first statement is to let everyone know that this is a very difficult job. The happiest thing is everyone’s feedback. Many people are willing to give five-star support.

Several points of special attention: 1. Before installation, use a DC cable to fully charge the battery (because the steering gear angle needs to be reset during installation, the battery needs to be charged). 2. Each time you install the steering gear arm, you need to turn on the switch once and turn on the switch to return to the steering gear. 3. Be careful not to install mirror images on the parts. let’s start!

Step 1：

Check the parts and charge the battery.The next step of installation can only be performed when the battery is charged, because the servo needs to be reset during the installation process. When the connection is correct, turn on the switch, and the servo will automatically reset.

Step 2：

The simplest, we first tear off the double-sided tape from the eyes and stick it on the capacitor. The angle determines the facial expression. It depends on you.Next, we install the four servos in the four grooves of the body. Note that the shaft side of each servo is biased to the outside relative to itself.The wire connecting the body servo, brown is negative, red is positive, and yellow is IO signal. Can not be inserted wrong. Pay attention to the color code on the check manual.Before installing the steering gear arm, you must turn on the switch once, and you will hear the sound of the four steering gears turning, which indicates that it has returned to its original position after turning. At this time, turn off the switch, and then install the servo arms in such a way that the four servos are perpendicular to the body at 90°.The teeth of the steering gear arm may have production errors, you only need to ensure that it is as vertical as possible. If the error is large, you can change the position of the steering gear arm to correct it.

Step 3：

The line connecting the four claw servos, brown is negative, red is positive, and yellow is IO signal. Can not be inserted wrong. Pay attention to the color code on the check manual. Before installing the steering gear arm, you must turn on the switch once, and you will hear the sound of the four steering gears turning, which indicates that it has returned to its original position after turning. At this time, turn off the switch, and keep the four steering gear arms parallel to the steering gear body.The teeth of the steering gear arm may have production errors, you only need to ensure that they are as parallel as possible. If the error is large, you can change the position of the steering gear arm to correct it.Install the steering gear to the four claws, pay attention to the direction of the arc consistent with the instructions, otherwise your spider may have four feet up to the sky. . . . .

Step 4：

For the installation of the four brackets, you can loosen the screws to install, of course, this is quite complicated. You caFind the position of the bracket, don’t engage in mirroring. For the installation of the four brackets, you can loosen the screws to install, of course, this is quite complicated. You can also just gently break the card and go in. Although it is fast, there is a risk of breaking. This is up to you.

Step 5：

If you strictly follow the precautions of the previous installation steps, you will get a spider without a cover, and the work has been completed 80%. At this time, when you turn on the switch, your spider will keep the look below after shaking its body, proving that you have installed it correctly.If you turn on the switch, it is not in this posture and the posture is strange, then it proves that you did not reset the steering gear angle correctly when installing the steering gear arm, or the steering gear arm angle was installed incorrectly, or the servo wire was inserted into the incorrect position.

Step 6：

Comb the wiring harness, let the wiring harness move freely in the gap of the bottom cover, tighten the bottom cover, tighten the top cover! The work is done!

Step 7：

Connect the robot and remotely control it! First, turn on the switch of the robot, turn on the WIFI of the mobile phone, retrieve the WIFI named ROBOT, and the password is 12345678. After connecting to the WIFI, turn off the GPRS to ensure that the WIFI is the only connection. If the mobile phone prompts that the network is unavailable, whether to continue, select Yes. Then open the browser and enter 192.168.4.1 in the address bar to confirm. The page opened at this time is the control page. We can control it with a mobile phone, a computer, or other equipment. Many friends keep asking me for APP after purchasing. After reading this, I believe everyone understands that it is controlled through a web page and does not require any APP. Good luck!
