Member Function Documentation

bool ArACTS_1_2::closePort (  void   )

Closes the connection. Closes the port to the ACTS server Returns: true if the connection was closed properly, false otherwise

bool ArACTS_1_2::getBlob (  int  channel, int  blobNumber, ArACTSBlob *  blob )

Gets the given blob from the given channel. Gets the blobNumber from the channel given, fills the information for that blob into the given blob structure. Parameters: channel  the channel to get the blob from blobNumber  the number of the blob to get from the given channel blob  the blob instance to fill in with the data about the requested blob Returns: true if the blob instance could be filled in from the

int ArACTS_1_2::getNumBlobs (  int  channel  )

Gets the number of blobs for the given chanel. Returns: the number of blobs on the channel, or -1 if the channel is invalid

void ArACTS_1_2::invert (  int  width = 160, int  height = 120 )

This will make the image stats inverted (for use with an inverted camera). This inverts the image, but since ACTS doesn't tell this driver the height or width, you need to provide both of those for the image, default is 160x120. Parameters: width  the width of the images acts is grabbing (pixels) height  the height of the images acts is grabbing (pixels)

bool ArACTS_1_2::openPort (  ArRobot *  robot, const char *  host = "localhost", int  port = 5001 )

Opens the connection to ACTS. Opens the port to the ACTS server Parameters: robot  the robot to attach this to, which puts a sensorInterp on the robot so that ArACTS will always have fresh data from ACTS... giving a NULL value is perfectly acceptable, in this case ArACTS will not do any processing or requesting and you'll have to use receiveBlobInfo and requestPacket (or just call actsHandler) port  the port the ACTS server is running on, default of 5001 host  the host the ACTS server is running on, default is localhost (ie this machine) Returns: true if the connection was established, false otherwise Examples: actsColorFollowingExample.cpp.

bool ArACTS_1_2::receiveBlobInfo (  void   )

Gets the blob information from the connection to acts. Checks the connection to the ACTS server for data, if data is there it fills in the blob information, otherwise just returns false Returns: true if there was new data and the data could be read succesfully

bool ArACTS_1_2::requestPacket (  void   )

Requests another packet. Requests a packet from the ACTS server, specifically it sends the request to the acts server over its connection Returns: true if the command was sent succesfully, false otherwise

bool ArACTS_1_2::requestQuit (  void   )

Requests that ACTS quits. Sends a command to the ACTS server requesting that ACTS quit Returns: true if the request was sent succesfully, false otherwise
