 +== Representing knowledge in a robot-agnostic ontology system for assistive robotics (MA Thesis) ==
  
-== Automated sensor calibration toolkit (BA/MA)==+The thesis will be jointly supervised by German Aerospace Center (DLR) in Munich and the Institute for Artificial Intelligence (IAI) at the University of Bremen.
  
-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.+Summary: 
 +  * Investigate about existing ontologies, like the Socio-physical Model of Activities (SOMA) from the University of Bremen. 
 +  * Refactor an existing knowledge database (known as the Object DataBase, ODB) used by the DLR into an ontology. 
 +  * Use the ontology to design tasks in the assistive robotics domain using assistive robots provided by the DLR
  
-The topic for this thesis is to develop an automated system for calibrating cameras, especially RGB-D cameras like the Kinect v2.+Full offer:
  
- {{ :kinect2_calibration_setup_small.jpg?200|}} +{{ :teaching:offer_2020-01_op2_wedanjustin.pdf |}}
-The system should: +
-  * 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:  +Contact: [[team:daniel_bessler|Daniel Beßler]]
-  * Good programming skills in Python and C/C++ +
-  * ROS, OpenCV+
  
-[1] http://www.halcon.de/+== Integration of novel objects into Digital Twin Knowledge Bases (MA Thesis) ==
  
-Contact: [[team:alexis_maldonado|Alexis Maldonado]] and [[team:thiemo_wiedemeyer|Thiemo Wiedemeyer]]+In this thesis, the goal is to make a robotic system learn new objects automatically. 
 +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.
  
-== On-the-fly 3D CAD model creation (MA)==+The focus of the thesis would be two-fold: 
 +  * 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. 
 +  * 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.
  
-Create models during runtime for unknown textured objets based on depth and color information. Track the object and update the model with more detailed information, completing it's 3D model from multiple views improving redetection. Using the robots manipulator pick up the object and complete the model by viewing it from multiple viewpoints.

-  * Good programming skills in C/C++ +  * Knowledge about sensor data processing

-== Simulation of a robots belief state to support perception(MA) ==+Contact: [[team:patrick_mania|Patrick Mania]]
  
-Create a simulation environment that represents the robots current belief state and can be updated frequently. Use off-screen rendering to investigate the affordances these objects possess, in order to support segmentation, detection and tracking of these in the real world. +<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++)

-== Multi-expert segmentation of cluttered and occluded scenes ==+== 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.
  
-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.+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:  +Requirements: 
-  * Good programming skills in C/C++ +  * Knowledge of 3D-Modelling tools. Blender would be highly preferred. 
-  * strong background in 3D vision  +  * Experience in Game Engine development. Ideally Unreal Engine 4 and C++.
-  * basic knowledge of ROS, OpenCV, PCL +
