8DOF Humanoid Biped Robot DIY Kit – 8 Servo Metal Frame Robot

Product Description

The 8DOF Humanoid Biped Robot DIY Kit is a compact and versatile robotics platform designed for students, hobbyists, makers, educators, and researchers interested in humanoid robotics and bipedal motion.

With 8 degrees of freedom, the robot provides 4 joints for the legs and 4 joints for the arms, allowing it to perform a variety of programmed movements such as walking, turning, dancing, arm swinging, and interactive actions.

The kit includes 8 high-torque MG996R/MG995 metal gear servo motors that provide the actuation required to move the robot’s arms and legs. The metal gear construction offers improved durability for repeated movement and robotic experiments.

The robot frame is manufactured from hard aluminium alloy, providing a strong yet lightweight structure. Multiple aluminium brackets and cup bearing assemblies are included to create the robot’s joints and mechanical structure.

A dedicated controller mounting area provides space for installing development boards such as Arduino, ESP32, Raspberry Pi, and other compatible controllers. The available mounting space also allows users to expand the robot with sensors such as ultrasonic sensors, IMUs, cameras, and other modules.

The kit is supplied as a DIY assembly, allowing users to understand the mechanical structure of a humanoid robot while developing their own movement algorithms, control systems, and interactive applications.

Specifications

Robot Structure

The robot uses an aluminium alloy mechanical frame consisting of multiple brackets, U-beams, foot bases, and bearing assemblies.

The leg structure is designed to provide the mechanical joints required for bipedal movement, while the arm structure allows the robot to perform swinging and other programmed upper-body movements.

The cup bearing assemblies help support rotating joints and can reduce friction during movement, contributing to smoother mechanical operation.

The modular bracket-based construction also makes the robot suitable for experimentation and customization.

Working Principle

The robot is controlled by the included servo motors. A suitable servo controller or microcontroller sends position commands to each servo to create coordinated movements.

By controlling the position and timing of the eight servo motors, users can create different motion sequences such as:

• Walking
• Turning
• Standing
• Arm movement
• Dancing
• Balancing experiments
• Interactive movements

A controller such as an Arduino, ESP32, or Raspberry Pi can be mounted to the robot’s structure and programmed to coordinate the servos.

An external servo driver such as a PCA9685 can also be used to simplify multi-servo control.

Expandable Design

The controller mounting area provides additional space for expanding the robot with external electronics and sensors.

Compatible expansion options may include:

• Ultrasonic sensors
• IMU modules
• Distance sensors
• Cameras
• Bluetooth modules
• Wi-Fi modules
• Battery monitoring systems
• Other robotic sensors

This makes the platform suitable for developing autonomous and interactive humanoid robots.

Important Notes

Assembly Required

This is a DIY robot kit and requires mechanical assembly. Basic tools and suitable technical knowledge may be required for assembly and setup.

Servo Controller

A suitable multi-channel servo controller such as a PCA9685 is recommended for controlling all eight servo motors.

Power Supply

The eight servos can draw significant current, especially during simultaneous movement or high mechanical load. Use a suitable 5V–6V high-current power supply, with approximately 5A minimum recommended capacity for the complete servo system.

Do not attempt to power all servos directly from a microcontroller’s 5V or 3.3V pin.

Mechanical Assembly

Ensure that all screws, brackets, servo horns, and bearings are securely installed before operating the robot. Proper mechanical alignment is important for stable walking and reduced servo load.
