Contexte et atouts du poste
Disclaimer
A PhDis nota continuation of coursework or a natural next step after a Master's degree. A PhD is a long-term, research-focusedcommitmentthat requires deepcuriosity,self-motivation, resilience, and a certaindegree ofautonomy.
By research, we meancreating new knowledge, not just applying existing theories. Your task is to discover, design, or prove something that no one has done before-work that will become what future students study.
If you are mainly looking for structured classes, predefined assignments, or a repeat of your Master's experience, you willlikely find this path unfulfilling. We welcome applications from candidates who are excited by uncertainty, driven to ask original questions, and eager to shape the frontier of their field.
Context & background :
Robots are physical agents that interact with their physical environment. Accordingly, their sensorimotor capabilities are essential and largely determine the activities that robots can perform. In recent years, great progress has been made in sensory capabilities thanks to significant advances in machine learning and dedicated hardware. In contrast, much less progress has been made in motor skills. Examples of promising approaches in the current scientific literature are Model Predictive Control (MPC) [1] and Model Predictive Path Integral (MPPI) control [2], where control actions are optimized over a finite time horizon, considering the time evolution of robot dynamics to optimize a given cost or reward function that describes the robot motion. Such algorithms are particularly suited foroptimizing control trajectories andplanning horizonsin real timedue to their ability to handle dynamic environments.
From a control perspective, planning a horizon that is as long as possibleto manage complex trajectories while considering the environment is essential. Additionally, maintaininga high control frequencyis crucial to meet thereal-timedemands imposed by real-world physics and, if necessary, to adjust the sequence of movements. In theresource-constrained context ofsmall-scale UAVs, such control algorithms are crucial as they enableoptimal trajectory generation and real-time decision-makingin complex, dynamic, and uncertain environments. However, particularly forbattery-powered UAVs, achieving a high control frequency while planning for a long horizon is difficult due to limited computational power and energy constraints [3], and conventional GPU acceleration often requires excessive energy consumption.
In recent years, hardware acceleration[4] has become increasingly popular, usingdedicated platformssuch asFPGAs(Field Programmable Gate Arrays) andASICs(Application-specific Integrated Circuits), increasing energy efficiency byorders of magnitude[5]. However, dedicated hardware acceleration for small-scale UAV control has not been proposed.
The PhD is in collaboration between the computer architecture team () and the robotics team () at Inria Centre at Rennes University.

Mission confiée
This Ph.D. thesis aims to usealgorithm-specific custom hardware accelerationto implementefficient real-time control for UAVswithlong prediction horizonsandhigh control frequencies. The structure of the control algorithms is complex and sensitive to numerical errors or reduced arithmetic precision. Thus, applying ahardware-algorithm Co-designapproach is necessary, i.e., adaptingthecontrol algorithms to the hardwareanddesigning the hardwareto suit the control algorithms optimally.
Principales activités
After a detailed study of UAV state-of-the-art control algorithms, the student will identify HW acceleration opportunities, such asparallelization, pipelining, anddata specialization. The student will applyco-designapproaches to realize efficient accelerators, utilizing the control algorithms' properties to improve the hardware while adjusting the algorithms to the hardware's characteristics.Simulationswill BE carried out to validate the proposed approaches and prepare the finalintegration in the UAV platform, which is already available to the RAINBOW team.
Compétences
Required technical skills :
- Good knowledge ofcomputer architecturesandembedded systems
- HW design : VHDL/Verilog basics, HW synthesis flow
