On the grid cell, this location would correspond to cell (x=3, y=4) because the grid map is 1 meter resolution.īut what if we wanted to change the map resolution to 0.1 meter spacing between each grid cell? Let’s suppose the robot reported its location as (3.5, 4.3). For example, let’s say a robot’s location in the real world is recorded as (3.5, 4.3). One other thing we need to keep in mind is that I assumed the map above has 1 meter spacing between each grid cell. Knowing what part of a factory floor is open space and what part of a factory floor contains obstacles helps a robot properly plan the shortest, collision-free path from one point to another. A robot’s position in the environment at any given time is relative to the corner of the map (x=0, y=0). We can use a grid map to abstractly represent any indoor environment, including a house, apartment, and office. However, open factory floor is located at (x=3, y=3). ![]() ![]() For example, we can see in the image above that a shelf is located at (x=6, y=8). The cool thing about a grid map is that we can determine what is in each cell by looking up the coordinate. An overhead view of a factory floor represented abstractly as a grid map with 1 meter x 1 meter cells. ![]()
