Manufacturing a Large Portion of the K1 Robot Body

A humanoid robot is made up of hundreds of mechanical, electrical and structural components. Each part has to fit into a larger system, and even a small dimensional deviation can affect assembly or movement.

For the Booster Robotics K1 project, our factory manufactured a wide range of customized CNC-machined components covering different areas of the robot.

These included:

Robot joint components
Arm and leg structural parts
Torso components
Motor and actuator-related housings
Connection brackets
Structural frames
Sensor mounting components
Precision mechanical interfaces
Customized covers and body components

Instead of treating every component as an independent CNC part, our engineering team considers how the parts will be assembled and used together.

This is particularly important for humanoid robots, where multiple moving components must maintain accurate alignment during repeated motion.

Why CNC Machining Is Suitable for Humanoid Robot Parts

Humanoid robot components often have complex geometries, thin walls, multiple mounting surfaces and tight assembly requirements.

CNC machining allows these features to be produced directly from customer CAD models and engineering drawings while maintaining consistent dimensions between different batches.

For complex robot components, 5-axis CNC machining can also reduce the number of setups required and improve positional consistency between different surfaces.

Our machining capabilities include:

3-Axis CNC Machining

Suitable for brackets, plates, housings, structural components and other parts with relatively straightforward geometries.

5-Axis CNC Machining

Used for complex components with multiple angled surfaces, curved structures and difficult-to-reach features.

CNC Turning

Suitable for shafts, cylindrical components, pins, bushings and other rotational parts.

Precision Drilling & Tapping

Used for mounting holes, threaded holes and connection interfaces required during robot assembly.

Materials for Humanoid Robot Components

Weight is an important consideration in humanoid robot design. Components need sufficient strength while keeping unnecessary mass under control.

Depending on the application, we machine different engineering materials, including:

Aluminum

Lightweight and suitable for structural frames, housings, brackets and robot body components.

Stainless Steel

Used where higher strength, wear resistance or corrosion resistance is required.

Titanium

Suitable for selected high-strength and weight-sensitive components.

Engineering Plastics

Materials such as ABS and other engineering plastics can be used for lightweight covers, prototypes, sensor-related components and non-load-bearing structures.

Material selection is based on the customer's drawings, application requirements and production conditions rather than using one material for every component.

From CAD Drawing to Finished Robot Components

For a humanoid robot project, machining is only one part of the manufacturing process.

Our production workflow typically includes:

1. Drawing & CAD Review

We review 2D drawings, 3D models, material specifications, tolerances and surface-finish requirements before production.

2. Manufacturing Process Planning

Our technical team evaluates machining methods, tooling, workholding and the number of setups required for each component.

3. CNC Machining

The parts are manufactured using our 3-axis and 5-axis CNC equipment according to the approved production requirements.

4. In-Process Inspection

Critical dimensions are checked during production to identify dimensional deviations before the parts reach final inspection.

5. Surface Finishing

Depending on the project, parts can be processed with suitable surface treatments such as anodizing, polishing or other specified finishes.

6. Final Quality Inspection

Finished components are inspected against the customer's drawings and specifications before shipment.

Quality Control for Robot Components

Humanoid robot parts often have multiple interfaces that connect with motors, bearings, sensors, fasteners and other mechanical components.

For this reason, our inspection process focuses not only on individual dimensions but also on the features that affect final assembly.

Our quality control includes:

Dimensional inspection
Thread and hole inspection
Critical tolerance verification
Surface-finish inspection
Material verification when required
Visual inspection
Assembly-fit checks where applicable
Final inspection according to customer drawings

For precision components, inspection equipment such as calipers, micrometers, height gauges and CMM equipment can be used according to the dimensional requirements of the part.

Engineering Support Before Production

One advantage of working directly with a CNC manufacturer is that manufacturing considerations can be discussed before production starts.

Our technical team can review:

Difficult-to-machine features
Thin-wall structures
Deep cavities
Hole and thread locations
Tool accessibility
Machining setups
Material selection
Tolerance requirements
Surface finishing requirements

When a feature may increase machining difficulty or cost, we can discuss a more practical manufacturing approach with the customer before cutting material.

This helps reduce unnecessary machining time and avoid potential problems during production.

Supporting Humanoid Robot Development from Prototype to Production

Humanoid robot companies often need different quantities at different stages of development.

Early-stage projects may require only a small number of prototype components for testing and assembly. Once the robot design is validated, production quantities can increase.

Our CNC machining service supports prototype and low-volume production, making it suitable for robotic companies that need customized mechanical parts without committing to large-volume tooling.

Whether the requirement is a single prototype, a small batch for testing, or repeat production, we manufacture components according to the customer's drawings and specifications.

Building the Mechanical Foundation of Humanoid Robots

Humanoid robots combine motors, sensors, electronics, software and mechanical structures into one highly integrated system.

The performance of the complete robot depends not only on its software and actuators, but also on the accuracy and consistency of the mechanical components connecting everything together.

Through the Booster Robotics K1 project, Jingcheng Dingyi has gained practical experience in manufacturing a broad range of customized humanoid robot components.

We continue to support robotics companies with 3-axis and 5-axis CNC machining for prototypes and low-volume production.
