Manipulator Massage System Based on STM32 Control

Abstract

With the computer gradually become an essential part of People’s Daily life. Long periods of sitting can lead to headaches, dizziness and cervical discomfort. In this paper, a manipulator massage system based on STM32F103 chip is designed to promote the intellectualization and automation of human cervical vertebra massage. Based on the study of human neck and shoulder massage points and massage techniques, the mechanical structure of the manipulator is designed, and SolidWorks is used to design the 3D model.

Autonomous Microcontroller-Based Aerial Water Sampling Device

“…However, when close to water, even wind speeds of less than 10 m/s can disrupt the system's ability to successfully sample water in several ways (1) The wind changes the air pressure around the body, resulting in large and rapid changes in the height recorded by the pressure altimeter. (2) The wind deflects the rubber-tipped dropper at an angle (5°), reducing the effective aspiration length and requiring the UAV to descend in altitude again, resulting in the flight system remaining in a critically stable state. (3) The wind disrupts the flow of water at the needle, resulting in less water entering the capture bottle.…”

“…However, The mission of this work required us to fly very close in order to achieve a high sampling success rate. During the sampling process this article set a 'target height' which the UAV attempted to maintain as it headed the dropper into the vial [2]. Overall, the flight system was able to operate the system normally without significant impact at water surface wind speeds ≤10m/s.…”
