Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple sensors are used to gather vast amounts of information about the environment, then the robot's perception capability is improved, but the data processing complexity and computational load increase
Solution Approach 1:
The system segments the data processing task by dividing it into multiple stages: sensor data acquisition, pre-processing/filtering, feature extraction, and final decision-making. The neural network is divided into multiple layers (input layer, hidden layers, output layer) that process information in sequential stages, reducing the complexity of handling vast sensor data at once.
Solution Approach 2:
The neural network acts as an intermediary between the sensors and the control system. It receives raw sensor data, processes it through multiple computational layers, and generates control commands. This intermediary layer simplifies the overall system architecture by consolidating complex processing tasks within the neural network module.
2Measurement precision
If AI models process vast amounts of sensor data in real time, then autonomous control accuracy is improved, but the processing speed and efficiency may be compromised
Solution Approach 1:
The system performs preliminary actions by pre-processing sensor data before it reaches the neural network. This includes filtering noise, normalizing data formats, and extracting relevant features in advance. The neural network itself is pre-trained on extensive datasets, so when deployed, it can make rapid predictions without performing full training computations in real-time.
Solution Approach 2:
The neural network focuses on processing only the most critical features and data points from the sensor input rather than analyzing every detail equally. The system processes data at different levels of detail depending on the situation - using simplified processing for routine scenarios and more intensive processing only when complex decisions are required.
3Adaptability or versatility
If a neural network engine with multiple models is used for autonomous control, then the robot's adaptability to dynamic environments is improved, but the system complexity and computational requirements increase
Solution Approach 1:
The neural network engine is designed as a universal control system that can handle multiple different tasks and environmental conditions through a single integrated architecture. The same neural network processes data from various sensor types (cameras, LIDAR, radar) and generates control commands for different maneuvers (steering, acceleration, braking). This multi-functional approach reduces overall system complexity compared to having separate specialized systems for each function.
Solution Approach 2:
The neural network architecture is designed to be dynamic and adaptable rather than static. It can adjust its processing behavior based on the situation - changing the level of processing intensity, selecting different subsets of sensors to activate, and adapting its decision-making strategy based on environmental conditions. This dynamic behavior allows the system to maintain high adaptability while managing computational resources efficiently.

AI summary

Each neural network model of the plurality of neural network models receives a subset of the data from the plurality of sensors. The plurality of neural network models generate, based on the data from the plurality of sensors, a plurality of outputs. Each output of the plurality of outputs is generated by a particular neural network model of the plurality of neural network models. Each output corresponds to a respective subset of data received by the particular neural network model of the plurality of neural network models. Thereafter, an output from the plurality of outputs is selected, where the output includes data for controlling the robotic device. The robotic device is then controlled based on the output.
