72/KIT. Spider bot
For this project, we will be taking a look at this particular kit titled the Freenove Quadruped robot kit, and assemble accordingly. This robot is special in the way it moves, which as we can see, uses 4 legs to move the body. The way the robot moves is that each leg has 3 servos, and each moves the leg in a synchronous pattern to make a step. Once the step from the first leg was done, the other leg follows the pattern to make another step. Eventually, the robot moves accordingly-similar to an insect or a spider.

There are many ways to control this robot after assembly, but for this part, we will be utilizing the Bluetooth remote control that comes with this kit. The remote allows you to not only make it go forwards/backward and left/right, but you can move the body in a stationary position.
To get started with the build, you will need to peel the paper backing of every acrylic part and make sure to organize it. There are separate instructions on the website as well as on the product page from Amazon, but to summarize, you will need to familiarize yourself with Arduino and upload the robot code to the Arduino mega, and the remote code to the remote controller.

Once the code is uploaded to each board, that is when you will assemble the chassis of the robot.
In summary, you need to attach the circle servo horn to the corners of the main body frame with tapping screws. once done, you will need to assemble the acrylic parts to the servo, where they need to be opposing each other. In other words, half of the assembled part stays in the original position, while the other half was in the opposing position.

Once all the servos were connected to all acrylic parts, then you will need to fuse them together so that they form joints. At this point, you should have 4 legs already assembled, so you can attach them to the body frame. Once you do, attack the bottom frame to keep the chassis strong and stable, and attack the Bluetooth modules to the board and the remote control so that they can pair up.
The instructions will also show you which port to connect to which servo and will show you how to assemble the remote control. As for the power supply, you can customize it, like using a 7.4-volt battery for both of these devices, and wire them up accordingly.

At this point, turn on the robot and the remote control, and test out the functions to see your robot come to life, and move according to the joystick position. to make it move while stationed, flip on the switches on the sides of the joystick, and control your robot.
This is more of an experiment than anything, but it's really fun to try out this unique robot!
