中文摘要为提高海上搜救的成功率,最大限度地减少生命和财产损失,需获得精确的漂移模型,并快速确定包含搜救目标的最小搜寻区域。对此,分析海洋环境、目标漂移特性等因素的不确定性对漂移运动的影响,提出一种新的风压差翻转率计算方法,并运用该方法建立搜救目标漂移模型。通过仿真试验,基于所建立的漂移模型,分别用解析法和Monte Carlo法对失事船舶搜寻区域进行估计。结果表明:风压差翻转率计算方法可提高漂移模型的精度;基于所建立的漂移模型,使用Monte Carlo法估计的搜寻区域能最大程度地包含搜救目标且面积小。
英文摘要A snake-like robot and its ground contacting mechanism with dual directional passive wheels were developed, and the technical solution for engineers to re-produce the corresponding modules was given. The performance of the robot in achieving serpentine locomotion by using the parameter α of the serpoind curve formula in given environments and its function of realizing turn motion based on amplitude modulation were tested. An infrared sensor was used to sense the geometrical properties of obstacles,and the robot can adopt the direct serpentine locomotion or the roundabout sperpentine locomotion to realize obstacle avoidance according to the measured geometrical properties of obstacles. The study provides the technical reserve for practicalizing snake-like robots.
