Data Glove with Accelerometer for Robot Hand Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for controlling robot hands via telepresence often require cumbersome operation, as the robot arm needs to be manually adjusted in x, y, and z directions to achieve a secure grip, which is inefficient and prone to errors.
Innovation Solution
A data glove equipped with additional sensors, such as a three-axis acceleration sensor or gyroscope, allows for the detection and correction of the robot hand's position and orientation relative to the object, enabling secure gripping without the need for a separate controller.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a separate controller is used to adjust the robot arm's position, then the robot arm can be precisely positioned, but the operation becomes cumbersome and complex
Solution Approach 1:
The patent combines the arm positioning function into the data glove by integrating additional sensors (accelerometer and gyroscope) that detect wrist movements. This merges the previously separate controller functionality directly into the glove, allowing users to control both hand grasping and arm positioning through natural hand movements without needing a separate controller device.
Solution Approach 2:
The system uses the user's own wrist movements to control the robot arm's positioning. The accelerometer and gyroscope sensors in the glove detect natural wrist motions and automatically translate them into corresponding arm movements, making the system self-controlling without requiring external controller operation.
2Adaptability or versatility
If multiple sensors are integrated into the data glove, then the control functionality is enhanced, but the device complexity increases
Solution Approach 1:
The data glove is designed to perform multiple functions using a unified sensor system. The same accelerometer and gyroscope sensors that detect wrist movements for arm positioning also work alongside the existing grasp detection sensors to control hand grasping movements, creating a universal control interface that handles both arm and hand operations through a single device.
