Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If pre-programmed responses are used in autonomous robots, then device complexity is reduced and ease of operation is improved, but adaptability to dynamic environments deteriorates
Solution Approach 1:
The patent implements a dynamic machine learning model that continuously adapts to changing environments rather than using static pre-programmed responses. The system dynamically updates its behavior based on real-time sensor data and environmental feedback, enabling adaptation to unforeseen situations while maintaining manageable complexity through modular architecture.
Solution Approach 2:
The autonomous robot performs self-learning and self-adjustment through integrated machine learning algorithms that process sensor data and automatically modify operational parameters. The system serves itself by continuously improving its environmental understanding and response strategies without requiring external reprogramming, thereby enhancing adaptability while keeping the control system relatively simple.
2Adaptability or versatility
If real-time deep learning is implemented, then adaptability and intelligence are improved, but use of energy and computational resources increases
Solution Approach 1:
The system implements partial real-time learning by prioritizing critical functions that require immediate adaptation while using pre-trained models for less time-sensitive operations. The machine learning model processes only the most relevant sensor data in real-time, performing partial actions that balance adaptability needs with energy consumption constraints.
Solution Approach 2:
The patent employs pre-trained machine learning models that are trained offline before deployment. This preliminary action transfers learned knowledge to the autonomous robot, reducing the computational burden and energy consumption during real-time operation while maintaining high adaptability for novel situations through transfer learning capabilities.
3Measurement precision
If multiple sensors and collaborative AI are added, then measurement precision and surveillance capability are improved, but device complexity and cost increase
Solution Approach 1:
The patent integrates multiple sensor types (LIDAR, cameras, GPS, gyroscopes) into a unified sensing system with centralized processing. This merging approach consolidates data from diverse sources through a common machine learning framework, achieving high measurement precision while managing system complexity through integrated architecture rather than separate independent systems.
Solution Approach 2:
The machine learning model serves multiple functions simultaneously - it processes data from various sensors for navigation, obstacle detection, target identification, and environmental mapping. This multi-functionality reduces the need for separate specialized systems, achieving comprehensive surveillance capability while controlling overall system complexity through a universal processing platform.

AI summary
An autonomous driving robot based on a two-wheel SEGWAY self-balancing scooter. Sensors including LiDAR, camera, encoder, and IMU were implemented together with digital servos as actuators. The robot was tested simultaneously with the functionality features including obstacle avoidance based on fuzzy logic and 2D grid map, data fusion based on co-calibration, 2D simultaneously localization and mapping (SLAM) and path planning under different scenarios both indoor and outdoor. As a result, the robot initially has the ability of self-exploration with avoiding obstacles and constructing 2D grid map simultaneously. A simulation of the robot with same 10 functionalities except data fusion has also been tested and performed based on robot operating system (ROS) and Gazebo as the simple comparison of the robot in real world.
