Come create the technology that helps the world act together

 

Nokia is committed to innovation and technology leadership across mobile, fixed and cloud networks. Your career here will have a positive impact on people’s lives and will help us build the capabilities needed for a more productive, sustainable, and inclusive world.


We challenge ourselves to create an inclusive way of working where we are open to new ideas, empowered to take risks and fearless to bring our authentic selves to work.

 

The team you'll be part of

 

Nokia Bell Labs is the world-renowned research arm of Nokia, having invented many of the foundational technologies that underpin information and communications networks and all digital devices and systems. This research has produced nine Nobel Prizes, five Turing Awards and numerous other awards.

The Nokia Bell Labs ISE Lab (Integrated Solutions and Experiences) is responsible for researching, designing, building, integrating, and delivering disruptive and best-in-class solutions and experiences that leverage the Bell Labs Research assets and innovations across multiple complex technology areas. We are looking for a strong and enthusiastic person with background, experience, and interests in RF networks and platforms to join a growing research group in Bell Labs that conducts research in distributed and networked control of autonomous robots.

 

What you will learn and contribute to

 

Wireless network communication is a crucial enabler of using cloud infrastructure for real-time control and coordination of industrial robotics. It provides almost unlimited computing resources, a high level of resource sharing, and increased system flexibility. However, ensuring the safety and performance of such industrial solutions requires ultra-low latency and ultra-reliable (URLLC) wireless communication. Although providing reliable connectivity for industry 4.0 is the promise of 5G and beyond, delivering guaranteed and reliable wireless service requirements for real-time wireless control (e.g., URLLC) has proven costly and inefficient, given the dynamicity and unpredictability of industrial environments.

As a part of the collaboration between Nokia Bell labs and Inria, the student will conduct research at Nokia networks France in the Nokia Bell Labs and Inria Valse teams.

 

Job Responsibilities

The thesis aims to design control and estimation algorithms that relax network latency and reliability requirements while ensuring the safety of the autonomous robotics applications in which the controller (motion control units) and the perception systems are located in the edge cloud. We address mobile robots as the primary target.

The expected results are the following:

  • Designing control and estimation algorithms by considering network-influenced variables (e.g., time-varying delay, packet loss, etc.)
  • Deriving mitigation methods to eliminate or reduce the influence of the network fluctuation in causing instability of the system
  • Demonstration of developed control/estimation algorithms and mitigation methods in real setups
  • Deriving additional metrics, combinations, or variations of existing metrics adapted for a communication system as Quality of Service metrics to abstract cloud-controller service.

 

Keywords

Mobile robots, Network control and estimation, Delay compensation
