The complete robot structure was digitally designed and validated using CATIA at 3DEXPERIENCE Lab, enabling precise modeling of mechanical components and assemblies. From an open source project made by a community oh Humanoid pationate people you can find here after :
The project combined mechanical design, electronics integration, embedded programming, and additive manufacturing to create a fully functional humanoid robotic system capable of coordinated movement and gesture-based operation.
All major robot components, including the head, torso, arms, joints, and support structures, were manufactured using 3D printing technologies to ensure lightweight construction and modularity.
Design & Aesthetics:
Humanoid CAD Design:
The robot components were modeled with a strong focus on biomimetic proportions and mechanical realism.
Complex curved surfaces and structural detailing were incorporated to replicate the appearance and movement of a humanoid system.
Lattice structures were integrated into selected regions of the robot components to reduce weight while enhancing the futuristic visual appearance of the robot.
During the CAD development process in CATIA, reference planes and partitioning techniques were used to isolate functional regions for lattice application and component optimization.
Variable wall thicknesses and reinforced joint regions were implemented to improve durability while maintaining smooth surface transitions and refined aesthetics.
CAD Assembly:
A full digital assembly of the humanoid robot was created to validate fitment, joint alignment, and component interaction before manufacturing.
The assembly process included the integration of servo mounting systems, joint mechanisms, structural brackets, and electronic housing sections.
Motion clearances and articulation ranges were analyzed digitally to ensure smooth movement across the robot’s neck, arms, hands, and torso mechanisms.
Exploded assembly views and hierarchical component structures were developed to streamline manufacturing and physical assembly processes.
Systems Engineering:
Embedded System Integration
The humanoid robot was developed using a systems engineering approach integrating mechanical systems, electronics architecture, and software control.
Servo motors, sensors, controllers, and power distribution systems were systematically integrated into the robot architecture for coordinated operation.
Control algorithms and motion sequences were developed for synchronized joint movement, gesture control, and responsive actuation.
Functional decomposition and subsystem-level integration were used to manage interactions between mechanical, electrical, and software domains throughout the development process.
3D Printing:
All structural and aesthetic robot components were fabricated using additive manufacturing technologies.
The modular printing strategy enabled easier manufacturing, reduced material consumption, and simplified replacement of individual components.
Different print orientations and support strategies were optimized to achieve improved surface finish, dimensional accuracy, and structural integrity.
Lightweight internal structures were incorporated into large components to reduce overall robot weight while maintaining sufficient mechanical strength.
Assembly of all 3D Printed Parts:
All 3D printed components were assembled into a complete humanoid robotic platform through a multi-stage integration process.
Servo motors, wiring harnesses, fasteners, bearings, and structural supports were installed and calibrated to ensure accurate motion and stable operation.
Joint calibration and positional tuning were performed to achieve smoother articulation and synchronized movement across multiple degrees of freedom.
The final assembly combined mechanical precision, embedded electronics, and digital manufacturing into a fully integrated humanoid robotic system.
