-== Fluid Simulation in Gazebo (BA/MA)== +== Scene Format Conversion Tool for Robotics Simulation (MA Thesis) ==
- {{ :research:fluid.png?200|}} +
  
-[[http://gazebosim.org/|Gazebo]] currently only supports rigid body physics engines (ODE, Bullet etc.), however in some cases fluids are preferred in order to simulate as realistically as possible the given environment.+**Motivation:**
  
-Currently there is an [[http://gazebosim.org/tutorials?tut=fluids&cat=physics|experimental version]] of fluids  in Gazebo, using the [[http://onezero.ca/fluidix/|Fluidix]] library to run the fluids computation on the GPU.+With robotics playing a significant role in various domains, simulation is essential for developing and testing algorithms. Multiple simulators are available, each with its own specialized format (SDF, USD, MJCF, URDF, FBX) for describing scenes. This diversity of formats makes it challenging to transfer scenarios between simulators. Therefore, a versatile parser that can convert scene descriptions between these formats is highly valuable.
  
-The computational method for the fluid simulation is SPH (Smoothed-particle Dynamics), however newer and better methods based on SPH are currently present +{{:multiformat.png?400|}}
-and should be implemented (PCISPH/IISPH).+
  
-The interaction between the fluid and the rigid objects is a naive one, the forces and torques are applied only from the particle collisions (not taking into account pressure and other forces).+**Task Description:**
  
-Another topic would be the visualization of the fluid, currently is done by rendering every particle. For the rendering engine [[http://www.ogre3d.org/|OGRE]] is used.+The objective of this project is to develop a universal parser capable of converting scene descriptions between common formats. The following key steps are involved:
  
-Here is a [[https://vimeo.com/104629835|video]] example of the current state of the fluid in Gazebo. +  - Create a model to represent and store the scene graph. 
 +  - Implement import functions for the model to handle scene descriptions in any of the supported formats. 
 +  - Implement export functions for the model to generate scene descriptions in any of the supported formats. 
 +  -  
 +**Requirements:**
  
-Requirements: +  * A strong passion for robotics. 
-  * Good programming skills in C/C++ +  * Dedication to the chosen topic. 
-  * Interest in Fluid simulation +  * Eager to learn.
-  * Basic physics/rendering engine knowledge +
-  * Gazebo simulator and Fluidix basic tutorials+

-Computer vision is an important part of autonomous robots. For robots the image sensors are the main source of information of the surrounding world. Each camera is different, even if they are from the same production line. For computer vision, especially for robots manipulating their environment, it is important that the parameters for the cameras in use are well known. The calibration of a camera is a time consuming task, and the result depends highly on the chosen setup and the accuracy of the operator.+Contact: [[team:daniel_bessler|Daniel Beßler]]
  
-The topic for this thesis is to develop an automated system for calibrating cameras, especially RGB-D cameras like the Kinect v2.+== Integration of novel objects into Digital Twin Knowledge Bases (MA Thesis) ==
  
- {{ :kinect2_calibration_setup_small.jpg?200|}} +In this thesis, the goal is to make a robotic system learn new objects automatically. 
-The system should: +The system should be able to generate the necessary models required for re-detecting it again and also consult online information sources to automatically acquire knowledge about it.
-  * be independent of the camera type +
-  * estimate intrinsic and extrinsic parameters +
-  * calibrate depth images (case of RGB-D) +
-  * integrate capabilities from Halcon [1] +
-  * operate autonomously+
  
-Requirements:  +The focus of the thesis would be two-fold: 
-  * Good programming skills in Python and C/C++ +  * Develop methods to automatically infer the object class of new objects. This would include perceiving it with state of the art sensors, constructing a 3d model of it and then infer the object class from online information sources. 
-  * ROS, OpenCV+  * In the second step the system should also infer factual knowledge about the object from the internet and assert it into a robotic knowledgebase. Such knowledge could for example include the category of this product, typical object properties like its weight or typical location and much more.

-== Multi-expert segmentation of cluttered and occluded scenes ==+<html><!-- 
 +== Development of Modules for Robot Perception (Student Job / HiWi) == 
 +In our research group, we focus on the development of modern robots that can make use of the potential of game engines. One particular research direction, is the combination of computer vision with game engines. 
 +In this context, we are currently offering multiple Hiwi positions / student jobs for the following tasks: 
 +  * Software development to create Interfaces between ROS and Unreal Engine 4 (mainly C++) 
 +  * Software development for our Robot Perception framework [[http://robosherlock.org/|RoboSherlock]] which contains many algorithms for computer vision problems (mainly C++)
  
-Objects in a human environment are usually found in challenging scenes. They can be stacked upon eachother, touching or occluding, can be found in drawers, cupboards, refrigerators and so on. A personal robot assistant in order to execute a task, needs to detect these objects and recognize them. In this thesis a multi-modal approach to interpreting cluttered scenes is going to be investigated, combining the results of multiple segmentation algorithms in order to come up with more reliable object hypotheses.+Requirements: 
 +  * Experience in C++. 
 +  * Basic understanding of the ROS middleware and Linux. 
 +The spoken language in this job is german or english, based on your preference.

-Contact: [[team:ferenc_balint-benczedi|Ferenc Balint-Benczedi]]+== Game Engine Developer and 3D-Modelling  (Student Job / HiWi) == 
 +A recent development in the field of AI is the usage of photorealistic simulations, for example to create Digital Twins of environments like households or  [[https://iottechnews.com/news/2021/apr/13/bentley-systems-nvidia-omniverse-create-real-time-digital-twins/|factories]]. 
 +In our research group, we focus on the development of modern robots that can make use of the potential of game engines. This requires a high degree of specialized game engine plugins that can simulate certain aspects of our research. Another important task is the creation of 3d models. 
 + 
 +Therefore, we are currently offering multiple Hiwi positions / student jobs for the following tasks: 
 +  * Modelling of objects for the use in Unreal Engine 4. 
 +  * Creation of specific simulation aspects in Unreal Engine 4. For example the development of interactable objects. 
 + 
 +Requirements: 
 +  * Knowledge of 3D-Modelling tools. Blender would be highly preferred. 
 +  * Experience in Game Engine development. Ideally Unreal Engine 4 and C++.
  
 +The spoken language in this job is german or english, based on your preference.
