AGV Material Dropping via Continuous Trajectory Planning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In material dropping processes, the stopping and restarting of Automated Guided Vehicles (AGVs) result in slow material dropping speed and efficiency, and collisions occur when one AGV breaks down in large workshops, disrupting the orderliness of material dropping operations.
Innovation Solution
A method and system that determine a motion trajectory and select a material dropping manner based on the positional relationship between the current and target dropping areas, allowing for efficient material transfer by avoiding occupied areas and optimizing movement paths, including linear and rotary dropping methods, to prevent collisions and improve safety.

Engineering Contradiction Analysis
1Reliability
If the material dropping trolley stops and restarts for material dropping, then the material dropping operation can be completed, but the material dropping speed decreases and efficiency is reduced
Solution Approach 1:
The patent implements continuous material dropping by allowing the trolley to drop materials during motion without stopping. The control device determines a motion trajectory and selects a material dropping manner (first linear dropping manner) that enables continuous dropping while moving, eliminating the need to stop and restart the trolley for each dropping operation.
2Productivity
If multiple material dropping trolleys work in large workshops, then material dropping capacity increases, but collisions occur when one trolley breaks down disrupting orderliness
Solution Approach 1:
The control device receives occupancy information from multiple trolleys and uses this feedback to determine safe motion trajectories. Before a trolley moves along a trajectory, the control device checks whether dropping areas on the trajectory are occupied by other trolleys, and only allows movement if the trajectory is unoccupied, preventing collisions and maintaining operational orderliness.
3Productivity
If the trolley moves continuously without stopping, then material dropping efficiency improves, but the risk of collision with other trolleys increases
Solution Approach 1:
The control device performs preliminary checks of the motion trajectory for occupancy before the trolley begins movement. By determining in advance whether the trajectory is unoccupied and only then allowing the trolley to move continuously, the system enables efficient continuous operation while preventing collisions through advance verification.
