Power Servos: 3 servos per leg, 18 in total Achieve multi-degree-of-freedom motion control

Body Structure: 3D-printed bionic skeleton with a hollow design to reduce weight while ensuring strength; the mechanical structure replicates the movement posture of a spider.

Expansion Interfaces: Reserved sensor interfaces for adding modules such as ultrasonic obstacle avoidance, infrared remote control, and posture sensors.

Functional and Play Highlights

1. Bionic Motion Control

Supports multiple gait modes: forward, backward, left and right translation, turning, and stationary rotation, replicating the crawling posture of a spider.

Gait can be customized via ESP32 programming, adjusting walking speed, stride length, and posture to achieve complex motion combinations.

Built-in balance control algorithm ensures stable walking even on uneven surfaces, preventing tipping.

2. Multiple Control Methods

Basic Remote Control: Supports wireless control via handheld controller/APP, allowing real-time control of the robot's movement direction and posture.

Programmable Custom Control: Code can be written using the Arduino/ESP-IDF development environment to achieve automatic obstacle avoidance, line following, and following functions.

Extended Play Options: Bluetooth/WiFi modules can be added for remote control via mobile phone; or sensors can be added to create an autonomous navigation robot.

3. Learning and Creative Value

Suitable for embedded development beginners, this course allows you to master ESP32 programming, servo control, and mechanical structure debugging skills through practice.

It provides a complete open-source resource package, enabling secondary development, such as adding LED lighting and sound effects modules to create a customized version.

Mechanical Structure and Design Advantages

Bionic Hexapod Structure: Each leg has 3 degrees of freedom, perfectly replicating the movement trajectory of a spider's legs, resulting in flexible and stable movement with a higher fault tolerance compared to quadruped robots.

Lightweight 3D Printed Body: The hollow design reduces weight and servo load while ensuring structural strength, preventing jamming even during long-term operation.

Modular Design: Each component uses a quick-release structure, making maintenance, servo replacement, or hardware upgrades convenient without requiring complete disassembly.
