Spherical Robot Weight Mechanism for Processing Status Indication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Spherical robots without hands, legs, or necks face challenges in notifying users of their processing status during dialogue, as they cannot move body parts to indicate processing time, leading to user uncertainty about the robot's state.
Innovation Solution
Incorporating a weight that rotates around a pivot within the robot's spherical housing, controlled by a drive mechanism to reciprocally move and indicate processing status through side-to-side swinging, allowing users to distinguish between processing and being out of order.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the robot performs predetermined processing that requires a predetermined time or more, then the robot can provide accurate response based on processing, but the user cannot determine whether the robot is under processing or out of order
Solution Approach 1:
The patent uses visual indication through lighting color changes to communicate the robot's processing state. The indication light displays different colors (e.g., blue for processing, red for error) to provide immediate visual feedback to users about the robot's operational status during predetermined processing, resolving the information loss about processing state.
Solution Approach 2:
The patent introduces an intermediary indication light that mediates between the internal processing state and the user's perception. This intermediary device translates internal processing states into visible external signals, allowing users to understand the robot's status without directly observing internal operations.
2Stability of the object's composition
If the robot remains stationary during processing, then the robot maintains a stable appearance, but the user cannot distinguish processing state from error state
Solution Approach 1:
The patent employs color changes in the indication light to convey operational status while maintaining the robot's physical stability. Different colors indicate different states (processing vs. error), allowing the robot to remain stationary while still communicating its operational status effectively.
Solution Approach 2:
The patent uses periodic blinking or pulsing patterns of the indication light to differentiate processing state from error state. During processing, the light may blink at a specific frequency, while in error state, it displays a different pattern, providing temporal variation to convey status information without mechanical movement.

AI summary
A robot including a spherical housing made up of a main housing portion, a first spherical cap portion, and a second spherical cap portion. The main housing portion is disposed between the first spherical cap portion and the second spherical cap portion. The robot further including a weight that is provided in the main housing portion and configured to rotate around a pivot that is orthogonal to a shaft connecting the spherical cap portions. When outputting a response to an input instruction received from a user, via an input device, based on a predetermined processing is determined to require a predetermined time or more, a robot controls a first drive mechanism during the predetermined processing such that the first drive mechanism rotates a weight around the pivot to reciprocally move the weight in the opposite directions of the pivot.
