SICK LMS 291

[Sena_Scott]

hi,

     SICK LMS 291 is a laser sensor whereby it sends and recevies hexadecimal codes. I'm thinking is there any way i can show the hexadecimal i get from SICK displaying it in a graph. Which kind of graph is more suitable? I'm using SICK to judge the distance between an object and the SICK. Attached file is roughly what i have make so far.. getting signal from SICK but jus unable to show it in the way i wanted.. Thanks.

Thanks for the link.. It helps a lot.. Here something i wish to try currently.. Is there anyway i can view the readings of the polar plot given by the SICK on my labtop using LabView wirelessly using TCP/IP whereas my SICk is connected to a CPU put on a robot..

There a number of ways to do this.  I would use remote front panels if you have the full or professional development package.

Hi,
     Just want to know is that any ways to make use of the data i obtained from the SICK sensor? Cause the data i obtained from SICK sensor, is some sort like a distance measurement, jus wondering is that any way i can use this readings to control my robot movement for obstacle avoidance? Thanks..

Sena_Scott,

At this point in time it might be best to contact the manufactor of the robot.  They will have a good idea about what type of data the robot can accept as well as what type of programming might be involved in sending the appropriate commands to robot.  I would also consult the user manual for the robot, it also may have some of the information about how to interface with the robot.

Thanks A_ryan,

                          Currently the robot is my school project which is built by my supervisor and my group.. So far the data is being transfer through the RS-232 into the labtop as the labtop is used as a interface for the user.. Any idea what kind of data is being transfer out of SICK LMS.. Below is a attached file, can you like point it out roughly which part is the most suitable part for me to extract the data from? Thanks

There is no attachment.  I guess I am not sure what more you want.  The VI's I posted in the link above should give you about everything you need.  There is a distance data point for every reading from the laser.  The angular position of that distance point is dependent on your model number.  With that information, you should be able to figure out the position and distance of obstacles.

I just noticed that you are using RS-232.  You will not be getting all of the data with that interface.  You need to use a 500K RS-422 interface to capture all the data points.

Thanks Brian.. I roughly get the idea already.. Thanks alot for the Help.. ^_^
