[Gearbox-users] [GearBox] Error when installing hokuyo_aist library

[Stanley L. <pro...@gm...>]

I'm having trouble installing the hokuyo_aist library. Gearbox has been
installed, running Player SVN 2.1, tried with Player trunk also. Have tried
with Linux versions 7.10 and 8.04.

I'm trying to run a UHG-08LX laser sensor.

Error is shown below:

I've added these to my bash.bashrc:



export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig/
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig/:$PKG_CONFIG_PATH
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib:$LD_LIBRARY_PATH
export PATH=/usr/local/bin:$PATH


Are my paths set up incorrectly??? I can't work out why it can't find it.

[Gearbox-users] API changes in hokuyo_aist, new Python bindings

[Geoffrey B. <geo...@ai...>]

I have just checked in a small change to the hokuyo_aist library's API. 
The following functions have been renamed:

unsigned int GetRanges (HokuyoData *data, double startAngle, double 
endAngle, unsigned int clusterCount = 1);
unsigned int GetNewRanges (HokuyoData *data, double startAngle, double 
endAngle, unsigned int clusterCount = 1);
unsigned int GetNewRangesAndIntensities (HokuyoData *data, double 
startAngle, double endAngle, unsigned int clusterCount = 1);

The new names are GetRangesByAngle, GetNewRangesByAngle and 
GetNewRangesAndIntensitiesByAngle, respectively. This resolves an 
ambiguity in the overloading of these functions and the functions used 
to retrieve range values by step rather than angle.

I have also added an initial version of Python bindings for this 
library. These will be built automatically if Python and Boost.Python 
are found. The shared module is installed to 
$PREFIX/lib/python/site-packages/, so this path must be in your 
PYTHON_PATH environment variable for the module to be located. An 
example is provided, installed to 
$PREFIX/share/gearbox/hokuyo_aist/example/. This example is a Python 
port of the C++ example.

Currently the full API is provided with two exceptions: the 
HokuyoSensorInfo object is not available in Python and the method of 
retrieving range and intensity values from a HokuyoData object is to ask 
for a single value each time using .Range (index) and .Intensity 
(index). These will be fixed in the future (near future, I hope).

I've only ever tested with the LMS291 (docs updated).

Ben, did you test with something else?

Which particular hardware models does the gbxsickacfr library support? 
The docs don't say.

I'm fine with USB, but I guess it should be mentioned in the docs 
(frustrating otherwise). I did a bit of digging around, but debugging 
custom serial code just ain't fun ;-).

Ah, ok. I'd argue that the base driver shouldn't worry about this and 
leave that to the user (somewhere in the glue layer), but that's 
definitely a matter of taste.

It happens relatively often, maybe every 5min. However, I didn't really 
investigate and it might as well be a problem in the quick and dirty 
hydro-wrapper that AlexM and I put together. Mainly I wanted to know if 
other people had seen the same behavior.
An exception seems appropriate, but transmission error I doubt (no 
checksum error).

Fair enough, let's keep it here.

Cheers,
Michael

Re: [Gearbox-users] [Gearbox-devel] urg_nz problem with serial interface

[Geoffrey B. <geo...@ai...>]

The new URG scanner I have unfortunately lacks a serial connection, but 
the older one I used to have did have one and I noticed exactly the same 
problem. Part of my research into the cause found that the Player driver 
suffered the same problem (not surprising), but I never determined the 
cause. Eventually I had to give up and attribute it to my hardware being 
faulty in some way. Obviously, though, that wasn't the case. I'll try 
and figure out why when I change the library to use the gearbox serial 
library. I can't get the scanner I have now to do it, but I only have a 
USB connection for it until I can dig up a serial cable.

min/maxIndex are necessary if the user wants to get less than the full 
scan back; they aren't just for filtering out the bits the laser can't 
see from the full "capable" scan range. I'm open to suggestions for a 
better way to do this, though (and I'll look at improving the 
documentation).

I've never seen my scanner return ranges beyond max_range, nor the 
scanner I used to have. How often do you get these values, and do you 
think that an exception is the best way to handle them, given that 
they're theoretically impossible and thus indicative of a transmission 
error?

I don't think you need permission do you? (since this is a public mailing

But no I have no objection.
