Ride-On Robot Control Terminal for Dual-Mode Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robots with rough terrain mobility are limited to operating either by wheels or legs, and require an operator to be seated, which restricts flexibility in operation modes.
Innovation Solution
A robot design that includes a main body for carrying a person, a handle for gripping, a moving device with leg portions and wheels, an attachable and detachable operation terminal, and a control device that allows operation in both riding and non-riding states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the robot is designed with a seat for operator to ride, then the robot can be operated in a riding state, but the operational flexibility is reduced because the operator cannot operate in a non-riding state
Solution Approach 1:
The operation terminal is designed to serve multiple functions: it can be attached to the robot for riding-state operation or detached for non-riding state operation. This single device replaces what would traditionally require separate control systems, enabling the robot to be operated flexibly in both riding and non-riding states without increasing overall system complexity
Solution Approach 2:
The operation terminal is made detachable rather than fixed, allowing it to dynamically change its attachment state. This dynamic configuration enables the system to adapt between different operational modes (riding and non-riding) without requiring complex permanent structures for both modes simultaneously
2Ease of operation
If the operation terminal is fixed on the robot body, then it is always available for operation, but it cannot be operated while the handle is gripped by the person
Solution Approach 1:
The operation terminal is designed with detachable mounting that allows it to be positioned in different locations based on operational needs. When attached, it can be mounted near the handle area allowing the operator to access both the handle and terminal simultaneously. The detachable nature allows repositioning without complex adjustment mechanisms
3Adaptability or versatility
If separate control devices are provided for riding and non-riding states, then operation in both states is enabled, but the device complexity increases
Solution Approach 1:
A single operation terminal is designed to function in both riding and non-riding states. The terminal includes necessary controls and display elements that work effectively whether the operator is seated on the robot or standing beside it. This universal design eliminates the need for separate control devices for different operational modes
Solution Approach 2:
The operation terminal is designed as a detachable, modular unit that can be independently configured for different operational scenarios. This segmentation allows the same physical device to be optimally positioned for either riding or non-riding operation, providing dual-state capability without requiring duplicate control systems

AI summary
A robot includes: a main body on which a person is carried; a handle to be gripped by the person on the main body; a moving device configured to move the main body; an operation terminal attachable to and detachable from the robot and configured to receive an input of a command related to an operation of the robot; and a control device configured to control the robot in accordance with the command received from the operation terminal. In a state where the operation terminal is attached to the robot, the operation terminal is disposed at a position where the operation terminal is operated while the handle is gripped by the person.
