From David Vandergucht

Position: Software Engineer, specialized on Inertial Measurement Unit on embedded systems.
At LOEMI laboratory, Institut national de l'information géographique et forestière (IGN, France)

In the context of a large-scale European nanotechnology project, IGN is seeking a software engineer specialized in Inertial Measurement Unit's data processing to contribute to the design of a real-time geolocalization system based on image processing (smart glasses).


Mission:

As part of a team of researchers and engineers in IGN's MATIS and LOEMI laboratories, you will participate to the building of a 3D pose estimation tool relying mainly on video streams processing and inertial sensors.

Your work will be focused on the inertial part. This tool will then be ported on a wearable embedded system developed by our partner CEA, but may also be used on UAV for 3D scanning tasks involving photogrammetry.

The mission contains four folds:

  • You will develop a high rate 3D trajectory reconstruction software based on gyroscopes and accelerometers.

  • The sensors planned to be used being targeted for consumer applications, their precision worth their (low) price. Hence, you will develop several filtering and calibration tools to cope with the quality of these sensors and limit the drift that tends to accumulate over time.

  • You will develop a data fusion system to combine the trajectory computed from the inertial data with the pose estimation retrieved by an image processing. The knowledge of the uncertainties of both sensors and processing methods should allow the fusion, but will also have to be recomputed and propagated over time.

  • You will develop an IMU calibration system based on information provided by image analysis.

The whole software being ported on a custom-designed System-on-Chip (SoC), a hardware acceleration of some of the functions may be possible via an FPGA chip.


Required skills:

  • Classical mechanics

  • Signal processing

  • 3D pose estimation

  • Kalman filter, particle filter, complementary filter

  • Very good knowledge of C++

  • Ability to read/write/talk fluently in English.

Bonus:

  • Agile methods

  • Knowledge of the ROS framework (Robotic Operating System).

  • VHDL/FPGA


Work location:

The research department of the French mapping agency (IGN) hosts four laboratories. Two of them, the MATIS and the LOEMI are specialized in computer vision, photogrammetry, image analysis, 3D modeling and remote sensing for the MATIS, and optical and electronic sensors for observations and measurement for the LOEMI. Those two laboratories are composed of more than 50 researchers and engineers whose publications are recognized in their fields.

IGN is a public institute located in Saint Mandé, France (immediate border with Paris), accessible in metro or RER. The location allows quick access to the Bois de Vincennes, hosts a corporate restaurant and propose several services included a large sports offer. Professional training and courses during the contract are available through our engineering school l'École Nationale Des Sciences Géographiques.


Project Context

This position takes place within the scope of a large-scale European Project: Things2Do (call KET-ENIAC 2013-2, 120M€). The project involves 45 academic and industrial partners from the nanotechnology field. IGN's laboratories contribute to the development of a wearable lightweight pedestrian navigation aid, in collaboration with Commissariat à l'Energie Atomique (CEA).

During four years, a fifteen people team of researchers and engineers will study and design a smart camera based on FDSOI architecture and computer vision techniques embedded on this architecture. A key goal is to allow a very precise pose estimate based on image and IMU rather than GPS signals.


Required qualification

High level education in software or electrical engineering (master of science or PhD)


Type/Contract duration

Location

CDD for 24 months.

We are hiring, ASAP.

IGN, Saint-Mandé (Paris, métro Line 1, RER Vincennes).


How to apply?

Before the 15/12/2015, please send an email to the contact address, with one pdf file containing:

  • a detailed resume with description of achieved projects.

  • A cover letter.

  • 3 contact names for recommendation.

Introducing A Better Inverse Kinematics Package

| No Comments | No TrackBacks
From Patrick Beeson via ros-users@

TRACLabs Inc. is glad to announce the public release of our Inverse Kinematics solver TRAC-IK.  TRAC-IK is a faster, significantly more reliable drop-in replacement for KDL's pseudoinverse Jacobian solver.

Source (including a MoveIt! plugin) can be found at:
https://bitbucket.org/traclabs/trac_ik.git

TRAC-IK has a very similar API to KDL's IK solver calls, except that the user passes a maximum time instead of a maximum number of search iterations.  Additionally, TRAC-IK allows for error tolerances to be set independently for each Cartesian dimension (x,y,z,roll,pitch.yaw).

More details:

KDL's joint-limited pseudoinverse Jacobian implementation is the solver used by various ROS packages and MoveIt! for generic manipulation chains.  In our research with Atlas humanoids in the DARPA Robotics Challenge and with NASA's Robotnaut-2 and Valkyrie humanoids, TRACLabs researchers experienced a high amount of solve errors when using KDL's inverse kinematics functions on robotic arms.  We tracked the issues down to the fact that theoretically-sound Newton methods fail in the face of joint limits.  As such, we have created TRAC-IK that concurrently runs two different IK methods: 1) an enhancment of KDL's solver (which detects and mitigates local minima that can occur when joint limits are encountered during gradient descent) and 2) a Sequential Quadratic Programming IK formulation that uses quasi-Newton methods that are known to better handle non-smooth search spaces.  The results have been very positive.  By combing the two approaches together, TRAC-IK outperforms both standalone IK methods with no additional overhead in runtime for small chains, and significant improvements in time for large chains.

Details can be found here in our Humanoids 2015 paper here:
https://personal.traclabs.com/~pbeeson/publications/b2hd-Beeson-humanoids-15.html

A few high-level results are shown in the attached (low-res) figure.

ROS 2 alpha2 (Baling Wire)

| No Comments | No TrackBacks
We're happy to announce the release of ROS 2 alpha2, code-named Baling Wire!

Installation instructions and tutorials designed to exercise new
features in ROS 2 are in the wiki:
  https://github.com/ros2/ros2/wiki

To get an idea of what's in (and what's not in) this release, be sure
to read the overview page:
  https://github.com/ros2/ros2/wiki/Alpha2-Overview

From that page, an important caveat that will persist for the next few
alpha releases:
~~~
As the "alpha" qualifier suggests, this release of ROS 2 is far from
complete. You should not expect to switch from ROS 1 to ROS 2, nor
should you expect to build a new robot control system with ROS 2.
Rather, you should expect to try out some demos, explore the code, and
perhaps write your own demos.
~~~

We're now on a ~6-week cadence for alpha releases.  We're continually
updating the roadmap to forecast what will be included in each alpha
release:
  https://github.com/ros2/ros2/wiki/Roadmap

As always, we invite you to try out the new software, give feedback,
report bugs, and suggest features (and contribute code!):
