[Urgwidget-users] Requesting bug fix

[Chris N. <nog...@vt...>]

Hi,

I was not able to install the code in Ubuntu 13.04 but adding the following
line:

*#include <sys/select.h>*

to the file called* urg_serial_linux.c *solved my problem.
Could you please fix this bug? Thank you.

Sincerely,

Chris

Hi,

The reason for this is the result of it is limited by the maximum value. 
  Since the confirmation later, could you wait a little more?

[Urgwidget-users] Rad to step to rad

[Quentin C. <que...@gm...>]

Here is an extract of my code, running on Linux Mint with an URG-04LX-UG01 :

urg_set_scanning_parameter(urg, urg_rad2step(urg, -PI/2), urg_rad2step(urg,
PI/2)
....
urg_step_min_max(urg, &min, &max);
printf("steps : min : %d, max : %d\n", min, max);

and it produces the output
"steps : min : -2.0XXXX, max = 2.0XXXX"
XXX cause I don't remember the exact output. Anyway, the thing is why isn't
around 1.57 and -1.57?

Thanks !

PS : I hope there are people on that mailing list....

I am not the author of the codes, but I suggested to implement
sufficient but minimal features to obtain range data from a sensor.  I
do not know much about old library features.

Sample program names show what kind of features are available.

  urg_library-1.0.4/samples/
    angle_convert_test.c
    calculate_xy.c
    find_port.c
    get_distance.c
    get_distance_intensity.c
    get_multiecho.c
    get_multiecho_intensity.c
    ld_setupapi.sh
    ld_wsock.sh
    open_urg_sensor.c
    open_urg_sensor.h
    reboot_test.c
    sensor_parameter.c
    sync_time_stamp.c
    timeout_test.c

Actually these are not the library, but sample codes.
The script  urg_library-1.0.4/windowsexe/compile.bat 
shows how they are compiled and linked.

If you want C++ version, look at forked project URG Network.
URG helper will never be updated.

  http://sourceforge.net/projects/urgnetwork/

The other forked project is Satofumi's work which may not be presented
in the net yet.

does the new library provide same set of features? I mean all features

[Satofumi K. <sat...@hy...>]

Dear Olzhas Adiyatov,

New library has also been added the function to get the data of 
multi-echo data.  You can use this function for the product of
UTM-30LX-EW and UXM-30LX-EW.

liburg depends on STL and SDL.  Because of this dependency it is
sometimes hard to integrate the library to other codes.

library is simple and independent.  It is easier to understand inside
and to be integrated to other codes.

Dear,



Hello!



I’m using the URG-04LX-F01. I’m debugging the old version. And I try to
copy the md_scan.c. while it looks like the urg.lib has some problem.



I want to use the new version, while I can’t know how to achieve the
continuous mode. I can understand the code easily in the old version.



So I turn to you for help. I will appreciate it if you can help me.

Hello!

 

I’m using the URG-04LX-F01. I’m debugging the old version. And I try to
copy the md_scan.c. while it looks like the urg.lib has some problem.

 

I want to use the new version, while I can’t know how to achieve the
continuous mode. I can understand the code easily in the old version.

 

So I turn to you for help. I will appreciate it if you can help me.

Dear Sir,

 

I am a student from Beihang University in Beijing, China. I have some question about the laser.

 

Our teacher bought us a Hokuyo laser range finder UTM-30LX. We have already made a project on our OS of Ubuntu and it works great. But when comes to the ARM board, it couldn’t transmit well. It always sending back the wrong data. The ARM board is Cubieboard, with an OS of Lubuntu, and I made a small kernel of my self. I’ve already known that UTM-30LX need the cdc-acm support to identify the device as /dev/ttyACM. I want to know if there are some else device drivers should I compiled in the kernel to communicate well with the laser.

 

I’m looking foward to hearing from you!

[Urgwidget-users] Rapid URG Not Spinning Up

[Nathan L. <na...@re...>]

Hi Guys,

I have just received a UBG-04LX-F01.  When the unit is powered up, the
green LED flashes while the laser mirror at the top spins up - however
after about 8 seconds the spinning stops.  This process repeats a few
times, until eventually the unit seems to 'give up' and all LEDs (1 x green
and 3 x orange) flash.  At this point the unit is unresponsive until power
is reset.

Am I doing something wrong?  Or do I perhaps have a defective unit?

Thanks!

Nathan

Perhaps, your programs try to connect the sensor by serial connection.
Please edit sample/open_urg_sensor.c like this to connect the sensor by
ethernet connection.


int open_urg_sensor(urg_t *urg, int argc, char *argv[])
{
     // ethernet connection
     urg_connection_type_t connection_type = URG_ETHERNET;
     long baudrate_or_port = 10940;

[Urgwidget-users] Using URG C library 1.0.4 with UTM-30LW-EW

[Markus D. <el...@le...>]

Dear Sir or Madam,

I am student at the Baden-Wuerttemberg Cooperative State University 
Stuttgart in Germany.
To realize driver assist systems for a Pedelec(electrical bicycle) and 
for projects relating to autonomous navigation we are using the Laser 
range finder UTM-30LW-EW.

To get into the programmation of the range finder I am using the URG 
Library 1.0.4 with Visual C++ 2010 Express. I tried to translate your 
explanations how to use this library.

Let me first explain what I've understood.
I opened the project "urg_library-1.0.4\visual_cpp\urg.sln". Visual C++ 
converted the project I think it's written in an earlier version. Then I 
started debugging by pressing F5. After compiling I have got the file 
"urg.lib" in the directory "Debug". I noticed that this library and the 
files in the directory urg_library-1.0.4\include are already included in 
the sample projects of "urg.sln". Then I wanted to execute one of those 
projects for example "get_distance". First I connected the range finder 
by ethernet to my PC and tested the functionality with the URG Benri 
V1.2.7 tool. That was working. After disconnecting URG Benri again I 
tried to debug the "get_distance" project on its own. Then I have got 
three files (get_distance.ilk, get_distance.exe, get_distance.pdb) in 
the directory "Debug". Nothing else happens. With double click on the 
.exe I there is appearing a console window for one moment but there 
seems not to be any connection to the range finder.

It would be great if you could help me by explaining how to use the 
library the correct way. In the first step it is just important to me to 
run your projects and to get some connection to the URG range finder.

Thank you very much in advance.

With kind regards
Markus Davin

Re: [Urgwidget-users] Are there any library for us to connect URG-04LX through USB to Arduino?

[Satofumi K. <sat...@hy...>]

Hi, Shang


I think that the urg_library will work syntactically if you are
porting a serial(USB) communication module.  But, I am concerned
that there is not enough memory in the Arduino.

I think making a new library for Arduino is good.
