Loader Control Learning for Repetitive Task Automation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Power machines, such as compact loaders, face challenges in efficiently performing repetitive tasks due to the need for continuous operator intervention, which can lead to reduced efficiency and increased operational time.
Innovation Solution
The implementation of a system that includes a learning mode where a home position is set, and a series of machine operations are recorded to perform a work task, allowing the loader to autonomously repeat these operations as needed, using controllers and computer programs to automate repetitive tasks like trailer loading and obstacle avoidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If continuous operator intervention is used to control the loader for repetitive tasks, then the operator can monitor and adjust operations in real-time, but efficiency is reduced and operational time increases
Solution Approach 1:
The loader system performs repetitive tasks autonomously without continuous operator intervention. The control system automatically executes recorded operation sequences, allowing the machine to serve itself by completing loading cycles independently, thereby improving productivity while reducing the need for constant operator input
Solution Approach 2:
The system records the operator's control inputs during a learning phase to create a predefined sequence of operations. This preliminary recording of actions allows the loader to automatically replay the same efficient operation sequence multiple times without requiring the operator to re-perform the complex coordination tasks each cycle
2Loss of information
If display panels are mounted in corners of the cab to provide operational information, then information can be displayed to the operator, but maintaining situational awareness of the work area becomes difficult
Solution Approach 1:
The display panel is integrated into the cab door glass surface, transforming the display from a corner-mounted 2D panel to a surface-integrated display that utilizes the vertical plane of the door. This dimensional repositioning allows information to be displayed in the operator's direct line of sight without requiring lateral head movement, maintaining both information access and situational awareness
