Sensor positioning involves determining the best location for a sensor to be placed or installed so that it can effectively sense or measure the desired physical or environmental parameters. In this paper, we present a novel approach for finding sensor positions on a robotic hand using machine learning techniques. We focus on pressure sensors and their placement in order to enhance the performance and reliability of gesture recognition tasks. Our study analyzes data from 22 sensors placed at different locations on a right-handed robotic hand, simulating 10 distinct hand gestures. We employ various machine learning algorithms and create a correlation matrix to determine the most relevant sensor positions. The results highlight the significance of sensor optimization in improving the overall efficiency and effectiveness of robotic hand systems. By reducing the number of sensors to 12, we were still differentiate 10 hand gestures with % 99 accuracy.
