研究目的
To develop a wearable hand motion capture device that detects finger motion and is equipped with an air cylinder for future force sense presentation.
研究成果
The sleeve sensor successfully detected finger motion with an error within 3 degrees, demonstrating the device's reliability for motion capture. Future work will focus on adding force and temperature feedback.
研究不足
The device has a weight of 540g and a movable finger range of 42 degrees; future improvements include integrating force and temperature sense presentation.
1：Experimental Design and Method Selection:
The device was designed with an exoskeleton made of acrylic resin using a 3D printer, incorporating four guiding structures based on finger motion trajectories. A sleeve sensor was used for displacement detection, connected to an air cylinder in parallel.
2：Sample Selection and Data Sources:
Motion trajectories were acquired from multiple sample data through human testing.
3：List of Experimental Equipment and Materials:
Air cylinder, sleeve sensor (ET850-L075, MACOME Co.), acrylic resin, 3D printer, transmission flexible wires.
4：Experimental Procedures and Operational Workflow:
The device was fabricated and evaluated by comparing theoretical and experimental angle-voltage characteristics of the sleeve sensor.
5：Data Analysis Methods:
Linear characteristics were analyzed, and error was calculated between theoretical and experimental values.
