The Orocos Project - RTT 1.x

Using Orocos to visually track a free-floating target in micro-gravity

The Robotics Demonstration and Test team, in the NASA Goddard Satellite Servicing Capabilities Office, used the Orocos ecosystem to control a Motoman SIA10D industrial robot to demonstrate autonomous visual tracking of both cooperative, and uncooperative, targets in microgravity.

Orocos 1.x for Windows?

qootec — Tue, 15 Mar 2011 16:22:22 +0000

Below, the story of an Orocos newbie...

What do I like to do? Get started with Orocos 1.x.

What is my preferred environment? C++, Windows, Eclipse

Is this realistic? I guess so:

Orocos has a 2.x version, so I suppose 1.x is super-stable and well-documented.
A first look at the site indicates that "RTT on MS Windows" is supported "out-of-the-box" as of 1.10.0.

So, here we go...

1) Start from http://www.orocos.org/wiki/rtt/rtt-ms-windows.

It indicates that 1.10.0 supports Windows out-of-the box, so that the work-arounds on this page are not needed anymore.

Fine. Click below to read the rest of this post.

Segfault when calling export function in non periodic activity

RenaudHeitz — Fri, 18 Feb 2011 14:43:54 +0000

Hi all,

I am using Orocos 1.10 under linux.

I use a component with non periodic activity : do setActivity("MyComponent", 0.0, 0, ORO_SCHED_OTHER )

I create a script with this function :

export function test() {

    //nothing

}

In the TaskBrowser : - I call MyComponent.test() a first time -> no pb. - I call MyComponent.test() a second time -> i get a segfault, my application crashes

Back trace :

Encoder Card with Orocos

cazalilla1988 — Tue, 15 Feb 2011 16:15:22 +0000

Hello.

I am doing a project with Orocos, and I need an analog output card and a encoder card. The analog output works successfully integrated into Orocos, using the class "ComediDevice" (and the card PCI-1720 by Advantech) but I can't integrate the encoder card.

I've looked at the list of "Supported Hardware" (http://www.comedi.org/hardware) and any two encoder cards appear in the list. Click below to read the rest of this post.

OCL Release 1.12.1 "undefined_referendce" and "sigfaul" (in xenomai)

cazalilla1988 — Mon, 24 Jan 2011 13:08:05 +0000

Hi.

Finally I succeeded to install the 1.12.1 version of OCL & RTT (to use the Comedi library), as well as having installed the latest toolchain. Well, I did "make install " (OCL & RTT) and the log show is installed everything correctly (in the correct directories.) - Attachments -

Modifying the component "HelloWorld", I created a function that runs on the "main"

include <ocl/dev/ComediDevice.hpp>
include <ocl/dev/ComediSubDeviceAOut.hpp>
include <rtt/dev/AnalogOutput.hpp>

....

void test () {

ComediDevice * comediDevAOut; unsigned int minor = 0; ComediDevice com... Click below to read the rest of this post.

In scripting, 1-1+1=-1

ThierryBultel — Fri, 21 Jan 2011 09:04:03 +0000

I am using RTT/OCL 1.10

This is due to the fact that the operation is evaluated as 1-(1+1) Is is fixable, or already fixed in a more recent version ? Thanks

peter — Thu, 23 Dec 2010 14:40:04 +0000

The Orocos development team is pleased to announce the first bugfix release of the Real-Time Toolkit v1.12, a C++ toolkit for building component based, real-time robotics and machine control applications.
