2012-04-07 13:58:22 -0500 asked a question LaserScan ranges values - left and rightmost scans.

I'm using a for loop to print out values retrieved from a Kinect LaserScan (specifically the "ranges" array). It returns 360 values, each with a number - most of the numbers are 11, but occasionally the numbers from 142-257 (I can't remember the exact range but it's something like that) are different. I believe these are the laser ranges? Am I wrong? Also, what are the numbers measure in? I normally get numbers between 0.5 and 10. If i'm mistaken, could someone explain how to get laser ranges from a kinect laser scan (i'm trying to get the leftmost and rightmost scans)?

2012-04-07 06:53:40 -0500 asked a question Kinect laser range - strange values.

I'm trying to get several value from my turtlebot's kinect laser (specifically the left-most and right-most laser ranges). I'm currently reading the sensor_msgs/LaserScan ranges array for those values. If I cover the laser with my hand, the values are read as 11 for some reason - can anyone explain this? Also, it seems like the laser doesn't fire as far as it possibly can - if I put the turtlebot in the middle of a room, the range values reported are also 11 (most of the time - if I put an object a few feet in front of the turtlebot, some of the ranges change. Is there a way to extend or set the kinect's laser range? Could someone clear this up for me?

I am trying to get the distance between the turtlebot kinect laser to a wall - could someone point me in the right direction - i've just started using the turtlebot.

2012-02-29 14:34:26 -0500 asked a question Creating 2d grid from laser scans.

Is there a way to create an OccupancyGrid without using the 2D SLAM libraries? I have a turtlebot firing laser scans while rotating - the lasers collide into the rooms walls. I want to create an OccupancyGrid showing where there are empty spaces and obstacles.
