The Player Project

Hi,
player cvs has this driver included, if you need a driver for player 1.6 
I can upload it to my website. My solution to the range problem for 1.6 
was to only return alternate scans and for cvs to increase the value in 
player.h.

Further to my previous email (which doesnt appear to ahve made it to the 
list yet?)

driver is in CVS, but since CVS isnt that stable at the moment here is a 
link to a player-1.6.x compatible version

Yes, indeed.  Toby Collett has done just this, and checked it into  
CVS.  It's a player 2.0 driver, so you'd have to work from CVS to try  
it out.  Alternatively, I think Toby mentioned that he has a player  
1.6 version of the driver; maybe he'll post it somewhere?

In part because of the URG, that value is 1024 in player 2.0.  The  
player 1.6 version of the driver probably skips scans in order to fit.

Yeah, it's quite cute.  Has anybody tried building a map with this  
thing yet?  I'm going to give it a try next week.

I've done some playing with the laser and pmap/amcl, seemed to work 
okay, no real numbers and I havent used the SICK for comparison.

Ill be interested to hear what you think of it once youve had time to 
try it properly.

Hi everyone,

I just got a URG laser scanner and I am trying to run it under linux. I am not using player but I took the urg drivers that are in player 2.0 (could not find any official driers from hokuyo!!). Everything looks fine, /dev/ttyS0 opens,  but there is no data coming from the file descriptor. (When set to non-blocking the errno is 11:Resource temporarily unavailable) Any idea why? Before this a "magic" string is sent to the scanner:  "G00076801\n", I am not so much into serial port programming, so I will be very grateful if anyone can shed some light on that too :) And lastly does anyone know if I can find a usb driver for the urg? Thanks a lot, any answer is appreciated.

-Ivan

You don't need a special driver to use the  URG with USB.  As long as
you have the acm or cdc-acm kernel module loaded, the URG should be
detected automatically as ttyacm0 (or possibly ttyacm1 etc).

I believe the driver in 2.0 assumes that you are using the USB
connection, so it won't work if you try to connect through serial.  It
wouldn't take much work to do this though.

Regarding the connection string, there is a document that describes
the communication protocol.  There should also be a sample project
that can help you work out the correct commands.  I don't have the
docs to hand, but if you don't have it, I can send it to you.

regards,

Jonathan

Hello!

I am trying to write a little client application, which is in charge of 
data logging, in a format that is convenient for the persons working in 
the same lab as me. I have to write down time stamps, and I am trying to 
do that for a laser and a position interface (sick and odometry values, 
in fact).
I wasn't able to find how to get those timestamps.

Does anyone know where I missed the point?

Regards,

Pierre


P.S. I have already written the same app with the C++ lib, which was 
successful. But for "didactic" purposes I now have to write it using 
libplayerc ;-)

the playerc_device_t structure has the timestamp in it, im not sure 
exactly how this is updated but I would assume it has the timestamp of 
the last processed message in it...

the playerc_client_t has a member datatime which should have the 
timestamp for the last data recieved for each individual device.

Is there no way, as when using C++ lib, to have a kind of "senttime"=20
timestamp, which would be much more precise?

Every libplayerc proxy structure has as its first member a field  
(usually called 'info') of type playerc_device_t.  This structure in  
turn has a field 'datatime,' which is the timestamp that the driver  
attached to the data currently sitting in the proxy (that's the most  
precise estimate you'll get of when the underlying phenomenon occurred).

For example, if you have a playerc_laser_t* called 'laser', you want  
laser->info.datatime (it's a double, representing seconds from the  
epoch).

Thanks. I personnaly don't care about sick scans timestamps, but it=20
seems that ma boss does, because his boss want timestamps.
I will use that!

Tank you very much.

Hi,
is there a Windows driver for the Hokuyo Laser? I'm programming in a project
and I have to use Windows but haven't found a driver yet. I have a driver
for Linux and I think it's not difficult to rewrite it for Windows, but I
don't know how to communicate with the USB port under windows (like
dev/ttsyACM0 under Linux)
Has anybody an idea?

Thanks a lot.

Hi,
The laser comes with software for interfacing to it in windows, if you 
do not have a copy of this I suggest you contact Hokuyo or check out 
their website.

In windows I dont recall *exactly* what happens with the ACM devices but 
from memory they appear as simply another COM port (COM5?)

Dear all,

I have bought one URG-04LX and I can read that it seems to be very good.
However, with the software provided, I have no signal going to it. I want to
apply this laser scanner to do 3D object reconstruction b y mounting it a a
robotic arm on top of a Pioneer platform.

The problem is twofold: I do not have proper documentation that would help
troubleshoot and the supplier is not responding to my messages. 

Do you have any suggestion on how to use the USB link ?

Hello Luc,

Im currently using URG on USB with Palyer and got it working quite 
easily. I dont know how much documentation you have, but I It should get 
working with following:
-Feed 5VDC(~500mA) to the marked "Power" pins in serial port of the URG
  (Apparently startup of the device is taking more than 500mA and thus not 
powered trough USB)
-Blug the USB gables
-Find URG in ur operating system and fix urglaser's port in your .cfg file 
(/dev/ttyACM0 in my SuSe Linux)
-Run Player
-Enjoy laserscans

Hope this helps,
Tapio

To use the laser via USB you still need to apply power via the other plug.

Dear all,

I thank Tapio for the very useful answer.

The 5VDC voltage source has to come through the serial link, otherwise it
does not work. 
It is quite important to notice that the Hokuyo URG laser range scanner
cannot be powered by the USB physical connection. 
I have measured a 650 ma rush current at sensor start-up which exceeds the
USB capacities.

Another one was also difficult with this snesor type, you have to unzip
files which are compressed by a very esoteric standard. 
Then, care should be to properly install the USB driver. 

After that, all worked well. 

Now, I have a new problem related to configuration. As it is required on the
readme file provided with the URG-Configurer, I have updated to SCIP 2.0 and
now I cannot use the sensor anyhow.
Has anyone found a simple solution to that or will I have to return the
sensor to Hokuyo for arranging it like it is advocated by Sentek, supplier
of this sensor in Europe and North America ? 

Thanks for the help,

LHR
