在这里,我想计算机器人在atmega 2560中行驶的距离?我知道公式:距离=车轮的周长*马达的转速。但是我不明白如何将这个公式应用于下面的问题。
What is the approximate distance covered by the robot in 2 seconds, if OCR5AL=OCR5BL=0xB2. Given that, maximum speed at which the motors rotate is 300 rpm and wheels have a radius of 2.8cm.

OCR5AL is Output compare regis
我只是想用经度/纬度点来计算行驶的距离。我有2983223行数据。我一直收到这个错误,并且我的distance列在整个df中重复相同的值。
library(geosphere)
dtrav <- matrix(c(df$start_lng,df$start_lat), c(df$end_lng, df$end_lat), nrow=2983223,ncol=2)
df$distance <- distHaversine(dtrav)
Error: Assigned data `distHaversine(dtrav)` must be compatible with exist
我第一次使用Mapbox Matrix API。我试着得到两个点之间的行驶距离:
Point A -105.044052,40.541783
Point B -105.43421,41.2337
我的请求格式如下:

我得到的回应是:
