NodeMCU main control + expansion board

NodeMCU is an open source IoT platform, suitable for Arduino programming environment. The source code has been burned, and the code can be open sourced for secondary development, which is simple and easy to use. Expansion board reserved 8 servo motors, NodeMCU socket, easy to plug. Download data from the Micro-USB interface above.The following interface is used for charging, the blue terminal is connected to the battery.

Support multiple WIFI device remote control

It supports remote control of various mobile phones such as Android/IOS, and can also use a computer with a wireless network card device.

Open WIFI settings, search for "Robot-" WIFI device, default password: 12345678.

Enter in the browser bar: 192.168.4.1 IP address, get the interface as shown in the figure below, and start control.

3D printed structural parts

The full set of structural parts are made of PLA, and the parts are all printed by a 3D printer.

The place where the steering gear arm needs to be installed has been reserved, and the place where the screw needs to be installed has also been reserved for screw holes. The screw can be easily screwed in with a screwdriver.
