Solution Overview
Problem
Existing remote controlled vehicles lack the capability to perform difficult, dangerous, or hazardous tasks such as searching rubble, assessing radiation, breaching buildings, or providing security in high-risk environments due to limitations in terrain handling and equipment versatility.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If larger and more powerful motors are used to handle difficult terrain, then terrain handling capability is improved, but device complexity and size increase
Solution Approach 1:
The vehicle divides its motor system into multiple independent motor units, with each motor driving a separate wheel. This segmentation allows the system to achieve complex terrain handling capabilities through coordinated operation of multiple simpler motor units, rather than relying on a single complex motor system.
Solution Approach 2:
The motor controllers are designed to perform multiple functions: they can independently control each motor's speed and direction, enable zero-radius turning by coordinating left and right side motors in opposite directions, and provide mechanical coupling through the chassis for towing and breaching operations. This multi-functionality reduces the need for separate specialized mechanisms.
2Force
If a large vehicle is used to breach barriers and tow other vehicles, then breaching and towing capability is improved, but vehicle size and weight increase
Solution Approach 1:
The vehicle merges multiple functions into a single integrated platform: the high-torque motors provide both propulsion for difficult terrain and sufficient force for breaching barriers and towing other vehicles. The modular design allows these capabilities to be achieved in a compact vehicle without requiring separate specialized equipment.
Solution Approach 2:
The vehicle uses high-torque motors that deliver extreme force at low speeds, changing the force-velocity characteristic to prioritize breaching and towing capability over speed. This parameter change allows a smaller vehicle to generate the necessary force for heavy-duty operations.
3Object-affected harmful factors
If protective plates are added to deflect radar and small arms fire, then protection capability is improved, but vehicle weight and complexity increase
Solution Approach 1:
The canopy is designed with asymmetric protective plates positioned at specific angles and locations to optimize deflection of radar and small arms fire. The nose section and tail section have different plate configurations tailored to their specific protection needs, reducing overall material requirements compared to uniform protection.
Solution Approach 2:
Protective plates are strategically placed only where needed for protection against radar and small arms fire, rather than providing uniform protection throughout the vehicle. The nose section and tail section receive enhanced protection, while other areas have reduced protection, optimizing the balance between protection capability and vehicle weight/complexity.

AI summary
A remotely operated robotic platform comprises a base module mechanically coupled to a first wheel and a second wheel. A first motor is electrically coupled to a first motor controller and mechanically coupled to a first wheel. A second motor is electrically coupled to a second motor controller and mechanically coupled to a second wheel in order to provide zero-radius turning. An array of batteries is electrically coupled to a distribution bar and further electrically coupled to the motor controllers in order to provide power to the motors. A canopy is mechanically coupled to the base module where the canopy further comprises a nose section mechanically coupled to a tail section where the nose section and the tail section comprise protective plates in order to allow the remotely operated robotic platform to deflect radar.
