A first study text for a newcomer to the field.

In "Simultaneous Stabilization and Tracking of Nonholonomic Mobile Robots: A Lyapunov-Based Approach", the authors stated that the nonholonomy of mobile robots allows control of the system with less control inputs. A mobile robot is underactuated in nature, and it's often controlled with less number of control inputs than the system's degree of freedom (if dynamic is ignored). How does the nonholonomy of the system helps with that?

I am trying to build a software system which will sense the real word in 3D (and do some AI stuffs to detect obstacle etc). At present I am using the Microsoft kinetic / creative 3D depth camera for sensing the terrain in 3D. These sensors are Laser and IR based hence are limited in distance and the nature of material the rays are bouncing from (eg, sensing black surfaces are difficult than white one). I have also found hokuyu sensors, but they are very costly. Can anyone suggest some good and cost effective sensors to map the terrain in 3D?

3D sensor Options:

1. Stereo vision:

Pros: Cost effective

Cons: large processing, complex algorithm

2. Hokuyu:

Pros: Reliable Data, Visual Studio supported.

Cons: Costly, less range

3. Velodyne (Google Car):

Pros: Range, Reliable, Outdoor Capability,

Cons: Cost (75,000 USD ) , Mechanical spinning Unit,

I was reading an article on Euler-Lagrange systems. It is stated there that since M(q) and C(q,q') depend on q, it is not autonomous. As a result, we cannot use LaSalle's theorem. I have uploaded that page of the article and highlighted the sentence. (ren.pdf)

Then, I read Spong's book on robotics, and he had used LaSalle's theorem. I am confused. (spong.pdf)

I did some research, and found out that non-autonomous means it should not explicitly depend on the independent variable. Isn't independent variable time in these systems?

I am just starting working on vehicle decision making at intersections. I need a traffic simulation platform to

1)Find the transition probability among states of environment vehicle;

2)Test decision making algorithm for my ego vehicle;

3)Test my cooperative decision making algorithm that applies to a group of vehicles at intersection.

Indexed in the ISI Thomson - SCIE/CURRENT CONTENTS and in all major scientific databases, the International Journal of Advanced Robotic Systems is a peer-reviewed Open Access journal, published by InTech, which aims to present the latest research in robotics. 

Facts:

First issue: 2004

Periodicity: 4 time per year

Success story: In 2006, upon NASA's request, InTech published a special issue of ARS journal, to which NASA's scientists contributed their scientific achievements regarding the Mars Exploration Rover missions

Other facts: New design in 2011, online only, InTech's first publication, started in Vienna

At the moment the journal has an ongoing call for papers for a special issue that seeks to examine the state-of-art, to present original insights and up-to-date research results in the field of Robot Manipulators. Under the editorial guidance of Dr. Gerasimos Rigatos, the proposed special issue aims at analyzing recent advances in the design and applications of robotic manipulators with particular interest in problems of nonlinear estimation, multi-sensor fusion and control.

If you are interested in contributing to this special issue by submitting your research papers please visit InTech's invitation page:

For previous issues please visit http://www.intechopen.com/journals/show/title/international_journal_of_advanced_robotic_systems where you can read the journal online for free, like all other InTech's publications (academic journals and books).

Hi,

I've just joined the group and would like to let you know about an Open Access book, "Multi-Robot Systems, Trends and Developments", which has just been published and is available for FREE download at:

Edited by Toshiyuki Yasuda and Kazuhiro Ohkura of Hiroshima University, Japan, the book consists of 29 chapters and 586 pages covering the task oriented approach, bio inspired approach, and modeling/design.

Please visit, read, download and share the news with your friends and colleagues!

InTech was founded by robotics researchers, and I believe you will find a great deal of material of interest to you on our reading platform www.intechopen.com - absolutely free of charge!

Regards,

Nataly and the InTech team

The classical engineering approach of multi-agent systems (MAS) was Agent-centered MAS (ACMAS), the current emerging trend is to adopt the organization-centered MAS (OCMAS), what are the advantages and disadvantages of each of them and when it is preferred to use each of them?

Hi, Can anyone please suggest any Software agent development tool for Beginners- Preferably Java based (apart from JACK and JADE) or .Net based. Also if there any books which give a good idea about the agent communication languages and their implementation.

I clicked to join the group and was presented with a form to "Share with this group," so I suppose I will.

I'm currently running the High Level Logic (HLL) open source project, attempting to bring code to version 1.0 that was prototyped in a robotics project - although the HLL concept sprouted its first roots much earlier and is aimed at a very broad range of applications. It does use agent technology, which is why I decided to join this group.
