Autonomous Golf Cart Control Using User Routine Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional golf carts require manual operation via a remote controller, causing inconvenience and safety issues during golf games, especially when players unfamiliar with the cart's operation need to access it, and existing autonomous systems fail to stop or start without user input.
Innovation Solution
A routine-based cart system that recognizes specific user behaviors using IMU sensors and GPS, allowing autonomous driving and stopping/restarting based on user actions without remote controller input, with backup sensors and alarms for safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the golf cart uses autonomous driving by tracking the user's terminal, then the ease of operation is improved, but the reliability deteriorates due to safety accidents and inability to stop automatically
Solution Approach 1:
The cart system performs self-service by automatically detecting user behaviors through IMU sensors and GPS, and autonomously stopping or starting without requiring manual remote controller input. The system monitors user actions (walking, running, jumping) and automatically controls cart operation based on detected behavior patterns.
Solution Approach 2:
The system implements feedback by continuously monitoring user terminal behavior through sensors and using this information to automatically adjust cart operation. The cart receives real-time data about user movement states and responds by stopping or starting, creating a closed-loop control system that improves reliability while maintaining ease of operation.
2Reliability
If the golf cart requires manual remote controller operation, then the reliability is maintained through direct user control, but the ease of operation deteriorates due to inconvenience for multiple players
Solution Approach 1:
The cart system performs self-service by automatically detecting user behaviors through IMU sensors and GPS, and autonomously stopping or starting without requiring manual remote controller input. The system monitors user actions (walking, running, jumping) and automatically controls cart operation based on detected behavior patterns.
Solution Approach 2:
The system achieves universality by enabling multiple players to use the cart without manual control. The automatic behavior recognition system works for any user carrying the terminal, allowing seamless transitions between players while maintaining cart operation, thus serving multiple functions and users effectively.
3Productivity
If the golf cart continuously tracks the user terminal, then the productivity is improved through smooth operation, but the loss of time increases due to unnecessary foot traffic for cart access
Solution Approach 1:
The cart system performs self-service by automatically detecting user behaviors through IMU sensors and GPS, and autonomously stopping or starting without requiring manual remote controller input. The system monitors user actions (walking, running, jumping) and automatically controls cart operation based on detected behavior patterns.
Solution Approach 2:
The system applies preliminary action by proactively detecting user intent through behavior analysis before manual control is needed. The IMU sensors and GPS anticipate when the user will need to access the cart based on movement patterns, allowing the cart to stop in advance and eliminating unnecessary foot traffic and time loss.

AI summary
The present invention relates to a golf cart operating by recognizing a specific behavior of a user as a routine, and a golf cart control method therefor, and, more specifically, comprises: at least one remote controller (100) carried by a user, and a cart (200) capable of performing autonomous driving, stopping, and re-starting by exchanging signals with the remote controller (100), wherein the cart (200) recognizes the user behind the user and performs autonomous driving while keeping a predetermined distance from the user, and, if a specific behavior of the user is recognized, the cart (200) can stop or re-start in response to the specific behavior so that the user can conveniently use the cart even without issuing a command by using the remote controller (100) during stopping or re-starting of the cart.
