Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple sensors measure distances simultaneously or successively, then the robot can evaluate the surrounding environment, but signal interference between adjacent sensors causes measurement inaccuracy
Solution Approach 1:
The patent implements periodic action by enabling ranging sensors to perform obstacle ranging sequentially in a looping manner rather than simultaneously. Each sensor is activated in turn according to a preset sequence, creating periodic measurement cycles. This temporal separation eliminates signal interference between adjacent sensors while maintaining continuous environmental monitoring capability through the looping execution of the ranging sequence.
2Measurement precision
If adjacent sensors measure successively, then signal interference is reduced, but the total measurement time increases
Solution Approach 1:
The patent applies continuity of useful action through a looping mechanism that continuously cycles through all ranging sensors in sequence. After one complete loop finishes measuring all sensors, the system immediately restarts the loop without interruption. This ensures that environmental evaluation is continuous and up-to-date, minimizing the effective measurement time loss while maintaining high measurement precision through sequential sensing.

AI summary
The present disclosure provides a robot distance measuring method and apparatus as well as a robot using the same. The method includes: obtaining a plurality of relative position parameters of a robot from a plurality of ranging sensors; determining an installation distance between each two of the ranging sensors based on the plurality of relative position parameters; determining a sum of the installation distance of each looping arrangement of the plurality of ranging sensors based on the installation distance between each two of the ranging sensors; and enabling the plurality of ranging sensors sequentially to perform obstacle ranging according to a preset looping rule. Since the adjacent ranging sensors are avoided to range simultaneously or sequentially, the interference of the adjacent ranging sensors can be minimized, the accuracy of measuring the distance of the surrounding obstacles can be improved, thereby improving the navigation performance of the robot.
