1 PhD position – Early Stage Researcher (ESR) 7 

Project title: Radar perception

Place of employment and planned mobility: Örebro University, Sweden: 6 months – seconded to Bosch Rexroth, Germany: 9 months, Örebro University, Sweden or TU Munich, Germany: 9 months

Supervisory team: Achim J. Lilienthal, Henrik Andreasson, Christine Brach, Ralf Becker

Project tasks and objectives: To use radar as a sensing modality on mobile robots has attracted increasing interest over the last years and its widespread introduction is expected to have a substantial impact for mobile service robots in industrial applications. Especially its resilience to smoke or dust and challenging weather conditions (such as heavy rain, fog or snow) presents a substantial advantage compared to lidar or visual perception, for example. Recent developments in hardware and novel perception algorithms have paved the way towards robust radar approaches to odometry, localization and mapping that can deal with the complex characteristics of radar signals (which can be difficult to interpret due to multipath reflection, speckle noise, and receiver saturation).

With a view on autonomous applications and long-term deployments, this project will set out investigating and quantifying the accuracy that can be achieved for odometry, localization and mapping with different state-of-the-shelf radar systems, particularly in comparison to respective lidar solutions. Based on these initial comparisons, using available and newly collected data, and building on expertise at Örebro University, Bosch Rexroth and TU Munich, the development of novel 2D and particularly 3D radar approaches (possibly combining classic and AI components) is a central goal in this project. Another aim is to evaluate the suitability of radar solutions (alone or in addition to lidar) for Simultaneous Localization and Mapping (SLAM) in changing environments. It is also planned to further develop approaches that evaluate partial results (e.g., after registration or map updates) with the goal to identify possible issues so as to be able to detect and remedy them online (radar introspection).

In this project, the ESR will acquire deep knowledge of state-of-the-art radar hardware and radar perception algorithms leveraging classic and AI approaches. The ESR will have the chance to shape the future in mobile robotics and further gain experience working in an international environment in academia and industry. The ESR will also be involved in dissemination through social media promotion of the network, such as Webropol surveys, and LinkedIn groups, YouTube video channels, Twitter and blogging.  

Starting date: April 1st, 2023. Negotiable.

Duration of the work contract: 24 months/full-time contract with the intention to extend to a full PhD thesis (48 months).

Trial period: 6 months. 

Target degree: Licentiate degree [1] from Örebro University, Sweden. Possibility for a PhD degree from TU Munich, Germany.

Approximate gross salary: about 3600 EUR/month plus family allowance if applicable

Eligibility: ESR shall at the date of recruitment, be in the first four years (full-time equivalent research experience) of their research careers and have not been awarded a doctoral degree. The researcher must not have resided or carried out his/her main activity (work, studies, etc) in the country of his/her first employer (Örebro University, Sweden) for more than 12 months in the 3 years immediately prior to his/her recruitment. 

The applicant must be in possession of a Master of Science (MSc) diploma at the beginning of the employment in engineering, computer engineering, mathematics, automation, or similar.

Additional information

Working and living conditions in Sweden at Örebro University Ph.D. students in Sweden are University employees and they have all the social and financial rights of other employees. Among these: a fixed monthly salary adequate to the cost of living in Sweden, inclusion in the Swedish social security system, and at least 28 days of paid vacation each year. These conditions are guaranteed for three years as long as the requirements for the Ph.D. studies are fulfilled. Ph.D. students in Sweden have to take advanced courses during their study program. These are typically technical courses relevant to their research project, but may also be courses about other related disciplines, including scientific methodology and project management. Courses at the Centre for Applied Autonomous Sensor Systems (AASS) are meant to provide students with a unique educational background in autonomous sensor systems. Ph.D. candidates in Sweden may devote up to 20% of their time to institutional work. This work typically consists in helping with the undergraduate education. The percentage of time spent with institutional work is added to the total duration of the Ph.D. studies. In summary, the Ph.D. students at AASS will be doing four sorts of things during their Ph.D.: work on their research project; take graduate courses; contribute to undergraduate education; and participate in the scientific life of AASS and of the international community. More information about the Ph.D. studies at AASS can be found here.            

The University of Örebro is a young university currently enrolling more than 14000 students. It is located in Örebro, a city with 130000 inhabitants, which is situated in central Sweden. For more information about the Universiy of Örebro click here and about the city, here.
