Chassis Concept Documentation
The chassis serves as the structural foundation for both Hyperion and Theia, providing support for all essential components, including mobility systems, electronics, and payloads. The chassis concept evaluation focused on effort to design, reliability, customizability, and ease of assembly to ensure optimal performance for each rover’s mission requirements.
Hyperion: Tank-Style Rover
Hyperion is engineered for extreme durability and resilience in demanding environments. Its 3D-printed frame is designed to provide structural integrity while minimizing weight, ensuring optimal performance in rugged terrain. The frame is reinforced to withstand high-impact forces and external stressors, making it ideal for traversing rocky, uneven landscapes. The modular construction allows for easy repairs and modifications, enhancing adaptability for long-term missions in unpredictable conditions.

Concept Evaluation Criteria
To ensure optimal drivetrain selection, the following weighted criteria were analyzed:
- Price (12.5%): Cost-effectiveness of manufacturing or procuring components.
- Effort (12.5%): Complexity of integrating and assembling the drivetrain.
- Reliability (25%): Structural integrity and durability of the treads or wheels in demanding environments.
- Customizability (50%): Ability to tailor the design for specific terrains and operational needs.
Decision Matrix
| Category | Weighting | Purchased Frame | 3D Printed Frame |
|---|---|---|---|
| Price | 0.125 | 0 | 1 |
| Effort | 0.125 | 1 | 0 |
| Reliable | 0.25 | 1 | 1 |
| Customizable | 0.5 | 0 | 1 |
| Totals | 1 | 0.375 | 0.875 |
Final Decision & Implementation
The final weighting and analysis results determined that the 3D-printed frame outperformed the purchased frame overall, offering significant advantages in price, customizability, and sufficient reliability while maintaining manageable assembly effort. Given the mission needs of each rover:
- Hyperion (Tank-Style Rover): Will utilize a 3D-printed frame to ensure a balance of durability and adaptability for challenging terrain.
Payload Assembly
The final analysis and testing results confirmed that the selected payload assembly design for Hyperion best meets the mission requirements by balancing secure deployment, modularity, and durability. The approach ensures the payload remains stable during navigation and can be deployed accurately at designated locations.
- Hyperion (Tank-Style Rover): Will use a servo-actuated payload release mechanism integrated into the 3D-printed chassis, ensuring precise and reliable payload drops in varied terrain conditions.
This implementation maximizes efficiency, minimizes failure points, and provides consistent payload delivery, critical to Hyperion’s operational success.
