Shared Remote Machine Control for Real-Time Operator Training
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current training methods for machine operators, such as those for dozers and excavators, are inefficient as they require extensive practice and often lack effective supervision, especially for novice operators, and existing remote control systems do not facilitate shared control or adequate communication for training purposes.
Innovation Solution
A training system that allows shared access and control of machines through a remote operation device, enabling a trainer to supervise and provide real-time feedback by receiving authorization to control the machine's traction and implement devices, while the operator is present, using video and audio communication to facilitate instruction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a second seat for a trainer is included in the operator station, then real-time supervision and instruction can be facilitated, but cost increases and valuable cab space is used
Solution Approach 1:
The patent creates a virtual copy of the trainer's presence through video feeds and audio communication systems. The remote trainer can view camera feeds from the machine and communicate via intercom, effectively copying the supervisory function without requiring physical presence in the cab.
Solution Approach 2:
The patent replaces the mechanical solution of adding a physical second seat with an electronic communication system. Video cameras, microphones, speakers, and control units work together to substitute the mechanical cab modification with an electronic supervision system.
2Adaptability or versatility
If multiple control devices are manipulated simultaneously, then complex machine tasks can be performed, but novice operators require many hours of practice to achieve proficiency
Solution Approach 1:
The patent implements real-time feedback through the communication system. The remote trainer can provide immediate verbal guidance, corrections, and instructions to the operator as tasks are being performed, allowing for rapid learning and correction of mistakes without requiring extensive trial-and-error practice time.
Solution Approach 2:
The communication system acts as an intermediary between the operator and the remote trainer. This intermediary enables continuous interaction and guidance, allowing the operator to learn complex multi-device coordination by receiving step-by-step instructions and real-time feedback from the experienced trainer.
3Ease of operation
If a remote control system is used for mining vehicles, then control from remote location is enabled, but shared control for training and adequate communication for instruction is not facilitated
Solution Approach 1:
The patent makes the remote control system universal by enabling multiple functions: normal operation, training mode with remote supervision, and emergency intervention. The same communication infrastructure supports both routine remote control and specialized training activities, eliminating the need for separate systems.
Solution Approach 2:
The system dynamically adjusts its functionality based on the operational mode. During training, the system enables two-way communication and video feeds for supervision. During normal operation or emergency situations, the system allows full remote control capability. This dynamic adaptability allows a single system to serve multiple purposes.

AI summary
In one aspect, a method for shared access of a machine for operator training, the machine including a traction device and an implement, includes receiving an authorization from an access device to share access to the machine, and entering a shared control state based on at least the authorization received from the access device. The method also includes receiving commands from a remote operation device during the shared control state and operating at least one of the traction device or the implement of the machine based on at least the commands from the remote operation device while an operator is present in the machine.
