罗盘定位除星星之外,磁性罗盘被视为人类长距离航行时主要的助手。罗盘的工作原理是:一根针指向地球的北磁极。只要你知道哪个方向朝北,就能很容易地重定旅行方向。机器人也能使用罗盘,多种电子和机电罗盘可用在业余的机器人中。最便宜的一种是由 Dinsmore 设备公司生产的 Dinsmore 1490。1490看起来像一个胖胖的晶体管,下面引出12根导线。每三根导线构成一组,共四组;每组主要代表一个罗盘指向:北、南、东和西。三根引线分别为电源、地和信号线。图11为安装在电路板上的 Dinsmore 1490。1490通过测量地球磁场提供了八个方向信息(北、南、东、西、东南、西南、东北、西北)。这使用小型的霍尔效应传
Compass positioning In addition to the stars, the magnetic compass is considered as the main assistant of human long-distance voyage. The working principle of the compass is: a needle points to the north pole of the earth. As long as you know which direction to head north, you can easily redirect your travel direction. Robots can also use the compass, a variety of electronic and mechanical compass can be used in amateur robots. The cheapest one is Dinsmore 1490.1490, manufactured by Dinsmore Equipment, which looks like a fat transistor with 12 leads underneath. Each of the three wires forms a group of four groups; each group mainly represents a compass that points north, south, east and west. Three leads were power, ground and signal lines. Figure 11 shows the Dinsmore installed on the circuit board 1490.1490 provides eight directions of information (north, south, east, west, southeast, southwest, northeast, northwest) by measuring the Earth’s magnetic field. This uses a small Hall effect pass
