Structural Team
The Structural Sub-Team focuses on the foundational elements of exoskeleton design, ensuring optimal force support, range of motion, and material selection. By balancing strength and flexibility, this team develops robust and lightweight frameworks that enable efficient performance and adaptability for users in demanding environments.
Component Modelling
Prior to design work, the team analyzed real-life lower limb ergonomics to research optimal frame configurations, ensuring designs aligned with anatomical and biomechanical principles.
SolidWorks, accessible to all general members, is used to model components with detailed material properties and stress simulations. This enables iterative improvements that reflect real-world performance. This technical approach ensures each prototype achieves both structural integrity and functional efficiency.
The following components are currently being iterated to be more lightweight, efficient, and cost-effective. The hip and knee joints are modelled using SolidWorks, while the waist link and leg straps are externally sourced.

Leg straps
Material Sourcing
The exoskeleton design incorporates carefully chosen materials to balance strength, durability, and weight. Velcro straps and lightweight plastic buckles are used for secure and adjustable leg fastening, providing comfort and ease of use. The primary frame consists of steel tubing, ensuring robust support while maintaining manoeuvrability.
PLA filament is utilized for 3D-printed components, offering a cost-effective and lightweight solution for custom parts. Together, these materials create a reliable and efficient design tailored to user needs.
3D Printing
Our team leverages three high-speed 3D printers to fabricate precise, custom components for the exoskeleton. These printers enable rapid prototyping, allowing for iterative design improvements and quick production of parts tailored to the project’s unique requirements.
By using PLA filament, we ensure lightweight, durable components that integrate seamlessly with the overall structure. This capability streamlines the development process, providing the flexibility to test and refine designs efficiently.
