Grass-Cutting Robot Attitude Control for Slope Balance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Grass-cutting robots face challenges in maintaining balance and precision while navigating non-ideal environments, such as slopes and obstacles, which can lead to ineffective cutting and safety risks due to loss of balance or deviation from the cutting route.
Innovation Solution
A control method for grass-cutting robots that detects their attitude and applies a control signal to create resistance in the travelling apparatus, hindering movement in a specific direction to prevent deviation and maintain balance, using sensors to detect conditions like proximity to boundaries, speed, turning speed, and angle relative to the horizontal plane.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the grass-cutting robot operates autonomously in non-ideal environments (slopes, obstacles), then the robot can work independently without human intervention, but the robot may lose balance or deviate from the cutting route
Solution Approach 1:
The patent employs attitude detection means to continuously monitor the robot's inclination angle and provides feedback to the control means. The control means processes this feedback and adjusts the driving forces of the left and right travelling apparatus accordingly, creating a closed-loop control system that maintains balance stability during autonomous operation on slopes and uneven terrain.
2Productivity
If the robot increases speed of advance, then productivity improves, but the robot becomes more prone to losing balance and deviating from route
Solution Approach 1:
The patent implements dynamic control by continuously adjusting the driving forces based on real-time attitude detection. The control means modifies the speed and force applied to each travelling apparatus dynamically, allowing the robot to maintain stability even at higher speeds or when encountering obstacles, thus resolving the contradiction between productivity and reliability.
3Force
If the robot applies more driving force to overcome obstacles, then the robot can maintain progress, but the robot may slip or lose balance
Solution Approach 1:
The patent applies different driving forces to the left and right travelling apparatus based on local conditions detected by the attitude detection means. When slippage or imbalance is detected on one side, the control means adjusts the driving force locally on that side while maintaining or reducing force on the other side, preventing overall loss of traction and balance.
