#define IGNORE_CLOSER_THAN_M 0.1

Do not mark any obstacle closer than this to center of the robot (avoid path planning deadlock).

#define IGNORE_FURTHER_THAN_M 0.5

Ignore data from sharp if further than this.

#define OBS_FORGET_PERIOD 100

The period of thread_obstacle_forgeting [ms].

#define OBS_FORGET_SEC 1

Time to completely forget detected obstacle.

#define OBS_OFFSET 0.6

#define OBS_SIZE_M 0.1

Expected size of detected obstacle.

Function Documentation

void obst_coord	(	struct robot_pos_type *	e,
		const struct sharp_pos *	s,
		double	v,
		double *	x,
		double *	y
	)

A thread running the trajectory recalc.

This (low-medium priority) thread updates the map with sensors information. If it is necesary, it recalculate the path.

Parameters:

arg

Returns:

Here is the call graph for this function:

Here is the caller graph for this function:

void obstacle_detected_at	(	double	x,
		double	y,
		bool	real_obstacle
	)

Then all the cells arround obstacle cell are set as MAP_NEW_OBSTACLE. Cells of current robot position are not set to avoid path planning deadlock. If there are a path cell between them, the path will be recalculated.
