| 125 | We completed intrinsic camera calibration for all three robots and extrinsic calibration for two of them (the terminator's camera is not mounted properly and we cannot perform calibration until we have some glue to fix it.) |

| 127 | A potentially serious problem we've realized is that the navigation tool is not remembering any landmarks. This is a big problem because landmarks are the way the robots remember obstacles they've encountered in a room and build a map of their surroundings. Originally it was thought that lack of calibration was the problem, but having calibrated the robots we find that at least Bender still does not catalog any landmarks in Navtool. I now suspect the culprit may be a broken communication link between the vSlam applet and the camera. An error in the logs warns us to check permissions on /dev/video0, which are set to 666 as I believe they should be. |

| 129 | Today, magically, the teleop applet was working with camera support on Bender. When we clicked a destination for the robot, it moved in generally the right direction, but passed the target and spent a long time colliding into the wall until we swithed off the battery. This is dissapointing, especially considering that the camera is supposed to be calibrated. |
