Mobile Object Route Control Using Temporary Via-Point Targets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional robots often inefficiently travel to destinations due to decelerating at each via point, which disrupts efficient movement.
Innovation Solution
A mobile object control device and method that sets temporary destination points between via points, allowing the object to travel efficiently without decelerating by setting and deleting these points as it approaches each via point.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the robot sets each via point as a temporary destination and controls itself to reliably pass through the via point, then the robot can ensure accurate passage through via points, but the robot decelerates before each via point which reduces travel efficiency
Solution Approach 1:
The patent segments the route into multiple via points and introduces temporary destination points between consecutive via points. This segmentation allows the robot to maintain higher speeds by treating intermediate points as temporary destinations rather than requiring full stops at each via point, thus resolving the contradiction between reliable passage and travel efficiency.
Solution Approach 2:
The patent introduces temporary destination points as intermediary elements between via points. These temporary destinations act as mediators that allow the robot to pass through via points without treating them as final stopping points, enabling smoother transit and preventing unnecessary deceleration while still ensuring accurate passage through the via points.
2Measurement precision
If the robot treats via points as temporary destinations, then the robot can maintain control accuracy, but the robot cannot travel efficiently to the destination via the via points
Solution Approach 1:
The patent applies preliminary action by setting temporary destination points in advance between via points. This allows the robot to plan its trajectory ahead and pass through via points without sudden deceleration, maintaining control accuracy while reducing travel time by avoiding repeated stopping and starting at each via point.

AI summary
A mobile object control device includes a storage medium configured to store computer-readable instructions, and a processor connected to the storage medium, in which the processor executes the computer-readable instructions to recognize a surrounding situation of a mobile object on the basis of at least an image of the surrounding situation of the mobile object, generate, on the basis of the recognized surrounding situation and a set destination, a route which is from the mobile object to the destination and is composed of via points to be passed through by the mobile object, control the mobile object so that the mobile object moves along the generated route to the destination via the via points, and when the mobile object travels toward a first via point of a plurality of via points, set a temporary destination point between the first via point and a second via point that is the next via point after the first via point, and cause the mobile object to travel toward the temporary destination point via the first via point.
