  1. There are two stages in isc : in the first stage the robot explores along the boundary of the environment , and in the second stage the robot plans the coverage path on line . by repeat covering some grids and setting the gate grids it not only guarantees the complete coverage , but also reduces the coverage repetition , thus improves the efficiency . there are no complex mathematical calculations in the planning which can meet the requirement of real - time and is fit for the embedded system
    Isc算法通过边界探索获得环境边界地图,之后在线规划覆盖路径,通过对部分栅格的重复覆盖和设置gate栅格保证了完全覆盖所有区域,而且也降低了重复覆盖率,提高了工作效率,同时该算法不用进行复杂的数学计算,保证了算法的实时性,降低了对内存的需求,适合于嵌入式软件。
