Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional robotic platforms are used in extreme environments, then they can navigate rugged terrain, but they fail to maintain functionality when they flip or change orientations
Solution Approach 1:
The robotic platform employs asymmetrical design elements including a non-symmetrical frame structure and strategically positioned sensors that can detect and adapt to inverted orientations. The suspension system uses asymmetrical tensioning mechanisms that allow the platform to maintain stability whether upright or inverted, resolving the contradiction between reliability during flips and adaptability to different orientations.
Solution Approach 2:
The platform is designed with inverted operational capability as a core feature. The payload support system can rotate 180 degrees to maintain proper orientation of sensors and equipment even when the platform itself is inverted. This inversion principle allows the platform to maintain functionality in both upright and inverted states, directly addressing the reliability issue during orientation changes.
2Adaptability or versatility
If the robotic platform uses a fixed payload support system, then the structure is simple, but the platform cannot maintain proper sensor orientation when inverted
Solution Approach 1:
The payload support system replaces fixed mounting with dynamic, movable components. The payload support can rotate about a longitudinal axis through gimbaled mounts, allowing it to adapt its orientation dynamically in response to platform orientation changes. This dynamic capability enables proper sensor orientation during inversion while managing complexity through controlled degrees of freedom rather than complex active control systems.
Solution Approach 2:
The gimbaled payload support system serves multiple functions: it maintains sensor orientation during normal operation, enables proper orientation during inverted operation, and provides shock absorption during transitions. This multi-functionality achieves adaptability without proportionally increasing complexity, as a single gimbal mechanism handles multiple operational requirements.
3Strength
If the robotic platform lacks suspension-tension system, then the structure is simpler, but it cannot absorb shocks during orientation transitions
Solution Approach 1:
The dual suspension-tension system is pre-configured with tensioning elements and shock-absorbing components positioned to provide immediate cushioning during orientation transitions. The system includes pre-loaded springs and tension members that are ready to absorb shocks before they occur during flips or inversions, protecting the platform structure and payload during transient events.

AI summary
A robotic platform or “bot” having a dual track mobility system. The bot is unmanned and autonomous, or may be controlled via remote control. The dual track dual suspension-tension system has first and second tracks positioned along lateral sides of the bot and extending longitudinally over a plurality of rollers. The bot may include suspension arms coupled to groups of the rollers on the ground facing sides of the tracks for suspension and the non-ground facing side of the tracks for tension in the tracks. The bot can operate in a first orientation and a second, vertically opposite orientation and maintain suspension capabilities in either orientation. The bot may include a payload mounted in a payload bay and that is configured to rotate in at least two axes. The bot may include a symmetrical sensor assembly configured to operate according to a reference frame controlled via a control system.
