Autonomous Working Robot Entry Control From Vehicle to Work Area
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous working robots, such as lawn mowers, often require manual intervention to move from a non-working area to a working area due to transportation vehicle limitations, reducing automation levels and increasing labor costs.
Innovation Solution
Equipping the robots with a driving assembly, sensor assembly, and controller that utilize sensing data and map data to autonomously navigate from a transport vehicle to a working area, avoiding manual carrying by determining entry and return conditions and controlling movement trajectories.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the transport vehicle parks near the working area, then the autonomous working robot can directly enter the working area, but the transport vehicle cannot park near the working area when obstacles are present
Solution Approach 1:
The movement process is segmented into two distinct trajectories: a first movement trajectory from the vehicle to a non-working area, and a second movement trajectory from the non-working area to the working area. This segmentation allows the robot to bypass the limitation of vehicle parking locations by using an intermediate non-working area as a transfer point.
Solution Approach 2:
A non-working area is introduced as an intermediary zone between the transport vehicle and the working area. The robot autonomously navigates through this intermediate area using sensor data and map data, enabling it to reach the working area even when the vehicle cannot park directly nearby due to obstacles.
2Extent of automation
If manual carrying is used to move the robot from the get-off point to the working area, then the robot can reach the working area, but labor costs increase and automation level decreases
Solution Approach 1:
The autonomous working robot performs self-service by autonomously navigating from the non-working area to the working area using its own driving assembly, sensor assembly, and controller. The controller processes sensor data and map data to generate navigation instructions, eliminating the need for manual carrying and maintaining high automation levels.
3Adaptability or versatility
If the robot autonomously moves from the vehicle to a non-working area, then the vehicle parking flexibility is improved, but the robot requires additional navigation capability
Solution Approach 1:
The sensor assembly and controller are designed with multi-functionality, serving both the initial autonomous movement from the vehicle and the subsequent navigation to the working area. The same sensor data and map data are utilized for both navigation phases, reducing the need for separate specialized systems and mitigating device complexity.

AI summary
An autonomous working robot including a sensor assembly configured to generate sensing data based on acquired information; and a controller configured to determine whether an entry condition is met, and perform an entry control process in response to the entry condition being met. The entry control process includes outputting a corresponding driving instruction according to the sensing data to control a first movement trajectory of the autonomous working robot moving from a vehicle transporting the autonomous working robot to a ground of a non-working area; obtaining map data of a working area of a working task to be performed; and outputting a corresponding driving instruction according to the map data and sensing data to control a second movement trajectory of the autonomous working robot moving from the ground of the non-working area to the working area.
