Solution Overview
Problem
Conventional power machines lack an efficient system for selectively executing local control of one power machine and remote control of another, especially when different types of power machines are involved, such as excavators and loaders.
Innovation Solution
A control system and method that allow a single operator to selectively control both local and remote operations of different types of power machines using an integrated user input device, enabling switching between local control of a first power machine and remote control of a second power machine based on user inputs.

1Productivity
If conventional power machines use separate human-machine interfaces for each machine, then each machine can be controlled independently, but the complexity of operation increases and operational efficiency decreases when multiple machines need to be coordinated
Solution Approach 1:
The control system allows a single human-machine interface to serve multiple functions by enabling one operator station to control both the local power machine and remote power machines. The system universally handles different control modes (local and remote) through the same interface, eliminating the need for separate control systems for each machine.
Solution Approach 2:
The patent combines multiple control functions into a single integrated control system. The local power machine's control interface is merged with remote control capabilities, allowing simultaneous or selective control of multiple machines from one location. This merging reduces the number of separate control systems needed.
2Adaptability or versatility
If a single operator controls multiple power machines, then coordination improves and the need for multiple operators is reduced, but the ease of operation decreases without an integrated control interface
Solution Approach 1:
The human-machine interface is designed to be universal, capable of controlling both local and remote power machines through the same controls. The system provides adaptability by allowing the operator to switch between controlling the local machine and remote machines while maintaining consistent operational procedures.
Solution Approach 2:
The control system acts as an intermediary between the operator and multiple power machines. It mediates control signals, routing them appropriately to either the local machine or remote machines based on system configuration and operator input, thereby simplifying the interaction between the operator and multiple machines.
3Adaptability or versatility
If different types of power machines are controlled from a single location, then operational flexibility improves, but the device complexity increases due to different control requirements
Solution Approach 1:
The control system achieves universality by designing a standardized interface that can control different types of power machines (e.g., excavators, loaders) through common control mechanisms. The system adapts to different machine types while maintaining a consistent operator experience, thereby providing operational flexibility without proportionally increasing complexity.
Solution Approach 2:
The control system is segmented into modular components that can be independently configured for different machine types. This segmentation allows the system to handle diverse control requirements through standardized modules, reducing overall system complexity while maintaining versatility.

AI summary
A control system is provided for a first power machine having a first actuator and a second power machine having a second actuator. The first power machine includes a first user input device. Aa first user input corresponding to a power machine operation can be received via the first user input device and a control mode for controlling the execution of the power machine operation can be determined. Controlling the execution of the power machine operation can selectively include: in a local control mode, controlling the first actuator to execute the power machine operation with the first power machine; and in a remote control mode, controlling the second actuator to execute the power machine operation with the second power machine.
