Additional Requirements

Connection with PC

First step is to make sure that the Sensor glove is connected to the USB0 and Robot Hand is connected to USB1. If this is not in order, we might have to change it inside the files and aslo in rosserial_python library. 

Connecting with ROS

  • Initiate Roscore with command: roscore
  • Run the Rosserial Python command to initiate the Serial connection between with the hand through Python:

          rosrun rosserial_python serial_node.py tcp

           You will see something like this:

  • After this, run the Arduino file to initiate the calibration. If the Serial connection is finished, you will see something like this:

Connecting with the Robot Hand

In order to connect with the hand, just run this file:

roslaunch rh8d start_rh8d.launch

GPU Cluster with eight A100

Getting started with Pytorch using Cuda acceleration

This tutorial gives an instruction on installing Cuda and enabling Cuda acceleration using Pytorch in Win10. Installation in Linux or Mac systems are all possible. An additional .py file will verify whether the current computer configuration uses the Cuda or not. The following instruction assumes that you have already installed Python IDE, e.g., Anaconda, Pycharm, Visual Studio…

Step 1: Check which Cuda version is supported by your current GPUs under this website. From the left figure, we can see that A100 supports Cuda 11.0. It is also reported from other blogs/ forums that A100 can support Cuda 11.1. In this post, we install Cuda 11.1.

Step 2: Download Nvidia Cuda Toolkit 11.1 (the same version as Cuda in Step 1) from the website. In Win10, for instance, we follow up the choice as shown right. The size of exe(local) is around 3.1GB. After downloading, run the .exe and perform installation. It may take some minutes to complete installation.

Step 3: On the homepage of Pytorch, choose the appropriate options as shown in the left figure. IMPORTANT: The cuda version must be the same as in Step 1. It is also recommended to use Stable version. After finishing the , copy the command into Anaconda Powershell Prompt or other command prompt where you install packages for Python. Waiting for the installation, which may require larger than 1GB disk space and takes some minutes for installation. You could also find historical version of Pytorch in that homepage.

Verify your installation with .py file

You could download a cuda-test.py file and run it. If the result shows ‘cuda’, then you can enjoy the Cuda acceleration for training neural networks!

Using Multiple GPUs for further acceleration

Running Pytorch with Multiple GPUs can further increase the efficiency. We have 8 GPU cards and can be used parallely for training. Please refer to (1) (2) (3) for details. 

Meeting Notes Template

Elmar Rueckert wiki_phds

As PhD you have to attach a meeting note to your personal profile post, e.g., Linus Nwankwo, M.Sc.. The notes have to be uploaded right after the meeting!

 

Clone this template and change the category to ‘notes_yourname’ (you may need to create this category first). You will need this category to display only your notes on your personal post. 

Make sure that the post you create is only accessible by the administrator and PhDs. In special case you may restrict the access only to you and your supervisor which is the administrator. 

 

The title of the meeting notes should contain the date and some keywords of the discussed topics. 

To attach the notes to your personal post, look at the example here. An image of the relevant section in your post is shown on top.

PhD Thesis Roadmap & Goals

Elmar Rueckert wiki_phds

Defining concrete measurable goals is of major importance for PhD students. 

These goals should be well crafted based on the research focus and the strengths of the student.

The goals form an agreement between the supervisor and the student. They can be used to evaluate the progress at any time. 

Your Thesis Topic in One Sentence

Every student should be able to explain their research topic and the scientific contribution in one sentence! 

Start thinking about it now. You will be asked dozens of times during your PhD at meetings or conferences.

What is your research about; and why is that important; and what is new; in one sentence. 

Thesis Topics

Ideally, your thesis consists of three parts or research topics. These parts might be adapted during the progress of the thesis. 

Each part should result an a journal publication and/or two conference publications. A good strategy is to first publish two short stories (= conference papers of 6-8 pages). Thereafter, the short stories are combined in a larger approach and published as journal paper. 

  1. Plan: planning future actions.
    Open research question: How can biologically inspired neural networks plan complex actions in few milliseconds?
  2. Act: Executing the actions. 
    Open research question: How can closed-loop controller be learned or generated from high-level plans?
  3. Sense: Sensing the environment and monitoring the execution. 
    Open research question: How to monitor the execution of neural closed-loop controller and to apply corrective actions in real-time?

Defining a Short Research Story

  1. Start by collecting the relevant related work to your research question. 
  2. Define an open unsolved problem and why it is relevant to the community. 
  3. Create measurable scores or goals how a solution to this open problem could be validated. 
  4. Also define 1-3 baseline algorithms or approaches which you will (re-)implement first. 
  5. Think about a toy task to demonstrate the principles. Typically, toy task simulations of point masses, simple 2D games or robot simulations in V-Rep are useful first case studies.
  6. Develop a relevant experimental setting to evaluate your approach. 
  7. Compute statistically significant statistics. Print Tables and Figures.
  8. Start by writing the results section of you paper. Describe the Tables and Figures first. Is your research question answered? 
  9. Continue with the methods section. Did you define a problem statement? Are your baseline approaches explained?
  10. Structure the collected related work and add it as subsection to the introduction.
  11. For the introduction, first write 1-3 sentences on the topic and the relevance. Next talk about the open problem and discuss the related work. Explicitly discuss your idea, own prior work and your contribution. 
  12. Write an abstract and a conclusion. 
 

Here are some examples.

Welcome to Leoben for Researcher

Elmar Rueckert wiki_phds

Organisational Steps before you arrive

For EU & Swiss Citizens: 

  • Get familiar with our Webpage and with the team.
  • Get in contact with our secretary. 

For Non-EU or Swiss Citizens: 

  • Get a Visa D for gainful employment (germ. VISUM D Erwerb) at an Austrian embassy. 
    Note that without that visa, it may take up to two months until you can sign your work contract, get an health insurance and, most importantly, get your first salary. 
  • With the Visa D for gainful employment, cou can immediately start to work and will have up to six month to get the Austrian residence permit at the local headquarters district (see below).
  • Also all points like for EU & Swiss citizens.   

Organisational Steps after your Arrival

There are a few very important things you need to do after you arrived. Please update the information if it is outdated. 

1. Get a Certificate of Registration from your Landlord

Once you signed the contract for your room or flat in Austria, you get a Certificate of Registration (germ. Meldebestätigung). An example is shown in the Figure on the left. If you did not get such a certificate, just print the PDF and get it signed by your landlord. 

 

2. Get a Registration Form from the City Hall

You need to go to the city hall (germ. Stadtgemeinde Leoben) to register your new main residence.  You will receive a Registration form (germ. Meldebestätigung). An example is shown in the left panel.

3. VISA or Residence Permit for Researcher

As researcher you can apply for a Residence Permit for Researcher. Sadly, the government’s information page is only in german. 

Below we outline the necessary steps for Non-Europeans. 

4. Get in contact via Email with the District Headquarters

To get a residence permit, you need to get in contact with the district headquarters Leoben (DH). Send them an Email or call them. The district headquarters will need from you: 

  1. A copy of your passport.
  2. Your Work contract.
  3. Your Registration form.

Once you send all your files to the DH, they will send you an appointment date via email. 

5. Documents required from Non-EU applicants

Find all important information on the page of the government. 

In order to obtain a residence permit, you need to contact the Bezirkshauptmannschaft Leoben. Send them an email or call them. The best way is to call them and inform them about your visa status. They will send you and appointment and you will need to submit the following documents:

  1. Completed and signed application form
  2. Copy of valid travel document
  3. Birth certificate (with translation)
  4. Proof of criminal record from the place of your residence (with translation). Note in some cases also records from your home country are needed!
  5. Current passport photo in the size of 3,5 x 4,5 cm (not older than 6 months)
  6. City Registration certificate
  7. Proof of legal entitlement to accommodation in Austria: e.g. rental contract, housing rights agreement.
  8. Proof of health insurance valid in Austria (probably only possible after starting work)
  9. Original admission agreement with the University of Leoben
  10. Original employment contract with the University of Leoben

6. Send all your Files to Mrs. Hotter

Mrs. Hotter of the Montanuniversität Leoben is responsible for new employees. Send her your files asap.
