摘要：
机器人系统在水质监测、污染测绘和生物多样性数据采集等水环境传感应用中展现出巨大潜力。传统部署方法往往会破坏脆弱的生态系统，无法还原未受干扰的环境状态。针对这一挑战，我们提出了一种新型框架，采用搭载传感单元的轻型翻滚系统，通过无人机进行部署。该设计通过保持缓慢下降速度，最大限度减少对水生栖息地的干扰。传感单元在到达水面后分离，可实现对底栖区域的精准、非侵入式数据采集。\n翻滚装置设计得轻巧紧凑，支持无人机部署。与翻滚装置分离后下沉至水体底部的传感舱，配备有温度传感器、压力传感器以及一套浮力系统。浮力系统在任务完成时启动，利用通过化学反应充气的硅膜工作。该反应产生70千帕的压力，使硅膜膨胀30%，超过了实现正浮力所需的5.7%的体积增幅。翻滚装置由环保材料制成，可减少任务中遗失时对环境的影响，我们对其滑翔比和下降速度进行了测试。它们的下降速度较低，处于每秒0.8至2.5米的范围内，可最大限度降低入水时对生态系统的干扰。此外，在户外测试中，该系统在中等至强风条件下表现出鲁棒性，验证了整个框架的可行性。
英文摘要：
Robotic systems show significant promise for water environmental sensing applications such as water quality monitoring, pollution mapping and biodiversity data collection. Conventional deployment methods often disrupt fragile ecosystems, preventing depiction of the undisturbed environmental condition. In response to this challenge, we propose a novel framework utilizing a lightweight tumbler system equipped with a sensing unit, deployed via a drone. This design minimizes disruption to the water habitat by maintaining a slow descent. The sensing unit is detached once on the water surface, enabling precise and non-invasive data collection from the benthic zone. The tumbler is designed to be lightweight and compact, enabling deployment via a drone. The sensing pod, which detaches from the tumbler and descends to the bottom of the water body, is equipped with temperature and pressure sensors, as well as a buoyancy system. The later, activated upon task completion, utilizes a silicon membrane inflated via a chemical reaction. The reaction generates a pressure of 70 kPa, causing the silicon membrane to expand by 30\%, which exceeds the 5.7\% volume increase required for positive buoyancy. The tumblers, made from ecofriendly materials to minimize environmental impact when lost during the mission, were tested for their gliding ratio and descent rate. They exhibit a low descent rate, in the range of 0.8 to 2.5 meters per seconds, which minimizes disturbance to the ecosystem upon water landing. Additionally, the system demonstrated robustness in moderate to strong wind conditions during outdoor tests, validating the overall framework.
