Pool Robot Recall Control for Safe Wall-Side Retrieval
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pool robots require manual recovery, leading to low recovery efficiency and potential damage due to collisions with pool walls and dirt accumulation on power cables.
Innovation Solution
A method and apparatus that automatically control pool robots to move to a designated stop position on the pool wall, using onboard sensors to map the pool and plan a path avoiding obstacles, enabling autonomous recovery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual recovery by pulling power cable is used, then the pool robot can be retrieved from water, but the robot may collide with pool wall causing damage
Solution Approach 1:
The pool robot autonomously navigates to the pool wall and positions itself for recovery without human intervention. The robot uses its onboard sensors and navigation system to identify the pool wall, plan a path, and execute the maneuver to reach the designated stop position, thereby serving itself during the recovery process.
Solution Approach 2:
The manual mechanical operation of pulling the robot by the power cable is replaced with an automated navigation system. The robot uses electronic control and autonomous path planning to move itself to the recovery position, substituting the mechanical pulling action with an intelligent control system.
2Reliability
If manual recovery by pulling power cable is used, then the pool robot can be retrieved from water, but dirt sticks to user's hands
Solution Approach 1:
The robot autonomously positions itself at the pool wall for recovery, eliminating the need for users to physically handle the robot or pull the power cable. The self-service capability ensures the robot retrieves itself to a safe position without contaminating the user's hands with dirt or water.
3Reliability
If automated path planning is implemented, then the robot can avoid obstacles in water, but the system complexity increases
Solution Approach 1:
The robot performs preliminary mapping of the pool environment during its operation, storing information about obstacles and pool features. When recovery is needed, it uses this pre-acquired information to quickly plan a safe path back to the wall, avoiding the need for complex real-time obstacle detection and decision-making during the critical recovery phase.

AI summary
A pool robot control method and apparatus, a storage medium, and an electronic device are provided. The control method includes: obtaining a start position of a pool robot existing when the pool robot executes a current task, where the start position is a water entering position or a pool bottom position of the pool robot in a target map at which the pool robot executes the current task, and the target map is a map established by identifying a target pool (S202); and when the pool robot needs to be recalled during execution of the current task or after the current task is executed, controlling the pool robot to move to a target stop position in the water of the target pool, where the target stop position is a position on a side wall of the target pool, where the position corresponds to the start position (S204).
