  • Coordinate Planes and Architecture
    ::协调规划和建筑

    Coordinate planes can be a useful tool for architects. Blueprints are usually laid out on a coordinate grid to help identify angles and side lengths.
    ::坐标机可以成为建筑师的有用工具。 蓝图通常放在坐标网格上,以帮助识别角度和侧长。

    For this interactive, you will use the distance between points on a coordinate plane to calculate the perimeter of a polygon.
    ::对于此互动, 您将使用坐标平面上的点数之间的距离来计算多边形的周界 。

    Making a Robot Part 9
    ::制作机器人第9部分

    Now that  the robot you began programming in the lesson is complete,  you can move the robot through  a maze. The function moveTo(x,y) has been added to  the commands. You can use this command to move a robot straight to a certain location, which may come in handy if  you need to move diagonally. Enter the x coordinate for x   and   y coordinate for y  of the location where you want to go. If you enter moveTo(5,6), this will move the robot in a straight line to the point (5,6), relative to the original starting location.
    ::现在课程中开始编程的机器人已经完成, 您可以通过迷宫移动机器人。 函数移动To( x, y) 已被添加到命令中。 您可以使用此命令将机器人直接移动到某个位置, 如果您需要移动对角, 则可以使用此命令。 输入 x 和 Y 坐标的 x 和 y 坐标, 您想要移动的位置 。 如果您输入 To( 5, 6) , 这将将机器人直线移动到点( 5, 6 6 ) , 相对于初始启动位置 。

    The list of all available commands is below:
    ::所有可用命令列表如下:

    • stepsYNo - This command will move the robot n steps forward, or n steps backward. The command stepsY(4) will move the robot 4 steps forward, and the command stepsY(-2) will move the robot 2 steps backward.
      ::stepsYNo - 此命令将移动机器人 n 步向前, 或 n 步向后。 命令步骤Y(4) 将移动机器人 4 步向前, 命令步骤Y( 2) 将移动机器人 2 步向后。
    • stepsXNo - This command will move the robot n steps right, or n steps left. The command stepsX(4) will move the robot 4 steps right and the command stepsX(-2) will move the robot 2 steps left.
      ::stepsXNo - 此命令将移动机器人 n 步向右, 或 n 步向左。 命令 stepsX(4) 将移动机器人 4 步向右, 命令 stepsX(-2) 将移动机器人 2 步向左 。
    • location() - This command returns two values, telling you the current x location and y location of the robot.
      :sad) 位置 - 此命令返回两个值, 告诉您机器人的 x - 位置和 Y - 位置 。
    • reset() - This command will move the robot to the starting position and will set the total number of steps taken to 0.
      ::重置 () - 此命令将把机器人移动到起始位置, 并将将所采取步骤的总数设置为 0 。
    • total() - This command will return the total number of steps taken by the robot.
      ::总计 () - 此命令返回机器人所采取步骤的总数 。
    • moveTo(x,y) - This command will move a robot to the x coordinate and y coordinate entered by the user.
      ::移动To(x,y) - - 此命令将把机器人移动到用户输入的 x - 坐标和 y - 坐标 。

    For the following interactive, you will be using everything you know about locations and distances on the coordinate plane to navigate a robot through a maze.
    ::在接下来的交互式操作中, 你将使用你所知道的 坐标飞机上的位置和距离 来导航机器人穿过迷宫。

     

     

     


    Science Connection
    ::科学连接

    This Physics Simulation involves a very similar robot motion and location system to the one  designed  over multiple lessons in this series.
    ::这种物理模拟涉及一个非常相似的机器人运动和定位系统,与本系列多个课程上设计的系统非常相似。

    See if you can identify the similarities and determine how the robot's programming might work.
    ::看看能不能找出相似之处 确定机器人的程序如何运作

     

      Summary
