Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the robot uses sensors to detect obstacles in varying environments, then the robot's ability to identify obstacles is improved, but the robot may still get stuck when encountering unexpected obstacle configurations
Solution Approach 1:
The robot dynamically adjusts its moving track and propulsion direction based on real-time sensor feedback. When an obstacle is detected, the processor calculates the appropriate adjustment angle and controls the roller circuit to change direction, enabling the robot to adapt to varying obstacle configurations and maintain continuous operation
Solution Approach 2:
The sensing circuit continuously provides feedback about obstacle positions and configurations to the processor. This feedback loop enables the robot to detect obstacles, determine appropriate response actions, and adjust its moving track in real-time, preventing the robot from getting stuck in unexpected situations
2Adaptability or versatility
If the robot adjusts its moving track to avoid obstacles, then the robot's adaptability to environment is improved, but the task completion time increases
Solution Approach 1:
The robot performs partial obstacle avoidance by adjusting its moving track only when necessary, rather than continuously changing direction. The processor evaluates sensor data and implements track adjustments only when obstacles are detected, minimizing unnecessary movements and reducing time loss while maintaining adaptability
Solution Approach 2:
The robot efficiently navigates around obstacles by calculating optimal adjustment angles and executing rapid track changes. The processor determines the most direct alternative path and controls the roller circuit to quickly transition to this path, reducing the time penalty associated with obstacle avoidance

AI summary
A robot includes a sensing circuit, a driving circuit, and a processor. The sensing circuit includes a first sensor and a second sensor. The first sensor is configured to receive a first sensing signal and the second sensor is configured to receive a second sensing signal. The driving circuit is configured to control an operation of a roller circuit and to control a forward direction of the roller circuit. The processor is coupled to the sensing circuit and the driving circuit. When the processor determines that, according to the first sensing signal and the second sensing signal, a sensing target is a bridge, the processor controls the roller circuit through the driving circuit to adjust the forward direction, such that the robot gets across the bridge.
