 Once these parameters are set, obstacle avoidance works very well. It is important to make sure the sensors are in fact pointing in the directions specified under (roll,pitch,yaw).

+We played around with joysticks for a little today. Between us, we have one Destroyer Tilt and one MS XBox 360 controller. We were able to get the Tilt working but not the Xbox controller. Oddly however, different applications reacted differently to being joystick controlled. Some programs, such as the odometry calibration script, were reluctant to respond to left and right motions on the joystick. We hope to iron out the details in using the joystick soon as it will be very useful for calibration. Ivan has given the go ahead to purchase one for Winlab.

+An exciting end of the day - we began writing a python script which will hopefully cause the robot to seek out the area of best internet connectivity. So far, the script is able to run iwconfig and extract the signal strength. It also has structures in place to keep track of three (x,y) coordinates and the signal strength at each of them. The functions written so far are: GoToXY(x,y) [Moves robot], scanning_thread() [returns signal strength], BigReading() [calls scanning_thread several times and returns average], Say() [calls ''flite'' for text to speech], Sort() [Sorts the three points in memory in order: best, good, worst], and PrintPoints() [prints BGW points to screen]. Python scripting is proving fast and easy, and we can probably have this working before lunch tomorrow.
