Detailed Description

A class that treats the robot's bumpers as a range device.

The class treats bumpers like a range device. When a bumper is bumped, it reports the approximate position of the bump in a buffer. The positions are kept current for a specified length of time.

Constructor & Destructor Documentation

ArBumpers::ArBumpers	(	size_t	currentBufferSize = `30`,
		size_t	cumulativeBufferSize = `30`,
		const char *	name = `"bumpers"`,
		int	maxSecondsToKeepCurrent = `15`,
		double	angleRange = `135`
	)

Parameters

currentBufferSize	The number of readings to store in the current Buffer
cumulativeBufferSize	The number of readings in the cumulative buffer (This currently is not being used)
name	The name of this range device
maxSecondsToKeepCurrent	How long to keep readings in the current buffer
angleRange	the range in front and behind the robot which is divided by the number of bumpers and used to detrmine where the sensor readings will be placed.

Member Function Documentation

	)

Parameters

bumpValue	This is the value that tells which individual bumper has been triggered
whichBumper	This value tells if the front or rear has been triggered
