相对于传统的轮式机器人,足式机器人拥有丰富的运动状态,可以适应复杂多变的非结构路面,其中环境检测能力以及稳定的步态控制是现阶段的研究难点之一.结合地形感知与遥控操作的六足机器人运动控制方法采用三维激光雷达实时监测环境,获取机器人周围三维点云数据与高程图信息.提出了基于激光雷达点云数据的自由步态控制算法,实现了遥控器控制机器人运动的功能.在ROS系统中搭建算法,在Gazebo软件中进行步态仿真,最后在真实环境中完成实验验证.为六足机器人在复杂环境中的精确运动提供参考.
Wireless Sensor Network(WSN)is an advanced Internet of Things(IoT)technology with many advantages and is wide-ly used in the field of smart agriculture.This paper proposes a smart agriculture architecture system based on wireless sensor networks,which adopts a partitioned and heterogeneous wireless sensor network architecture according to the geographic area and agricultural in-dustry,with the advantages of saving node transmission resources,distance,and energy,thus prolonging the network lifespan.The ap-plication methods of wireless sensor networks in the whole industry chain of smart agriculture are summarized to provide reference for related technicians.
Using the Framework framework,self-developed tools,combined with the basic work parameters,full customer TA dis-tribution and station spacing,the overreach coverage area was quickly located and the overreach coverage problem area database was formed.In addition,through the link budget and trigonometric algorithm,the automatic,fast and efficient identification of problem cells differentiated by scene and more accurate output of optimization and adjustment schemes,the accurate output of downdip adjustment schemes make up for the lack of effective means for the adjustment and optimization of existing on-site antenna feeders,which requires repeated on-site inspection and adjustment,and effectively support first-line production in cities and cities.Increase production effi-ciency and reduce optimization costs.
