Multi-robots autonomous exploration of un known environment in ROS
IMT Lille-Douai, France (2017-2019)
Post-Doc, research project
**Keywords**: `ROS, distributed system, middleware, robotic, mono and multi-robot SLAM, autonomous exploration, multi-agent, Vector map, PolySLAM`
**Skills**: `ROS, C, C++, Python, PharOS (ROS binding for Pharo Smalltak), TCP/IP, linux`
**CPER-Data** European research project: Working as researcher in the robotic domain, particularly in: autonomous navigation, SLAM, multi-robot SLAM and navigation. We worked on PolySLAM, a new SLAM algorithm that produces vector based maps (PolyMap). This kind of map proved its advantage in multi-robot context thanks to its compact format that reduces the network overhead when exchanging the maps in a collaboration (autonomous) exploration.
Software/FPGA Co-design for Edge-computing: Promoting Object-oriented Design
IMT Lille-Douai and ENSTA Bretagne, France (2014-2017)
PhD, research project
**Keywords**: `IoT, FPGA, edge-computing, middleware, Sensor network, Object Oriented, modelling, HW design, SW/HW co-design, embeded system`
**Skills**: `VHDL, middleware architecture, C, C++, Smalltalk, UML, FPGA, ARM, embeded linux, network programming, language virtual machine`
Edge-centric computing for IoT requires sensors nodes with more software capability and processing power while being constrained by energy consumption. Hybrid hardware systems consisting of FPGA and processor (ARM) offer a good trade-off for this requirement. Applications design for such hybrid network/software/hardware (SW/HW) system remains always a challenged task. Our motivation is to propose a homogeneous design methodology and environment for such system. We study the application of a modern design methodology, in particular object-oriented design (OOD), to the field of embedded systems. We aim at using OOD to develop a homogeneous design environment for edge-centric systems. Our approach addresses three design concerns: (1) *HW design, where object-oriented principles and design patterns are used to improve the reusability, adaptability, and extensibility of the HW system*. (2) *HW / SW co-design, for which we propose to use OOD to abstract the SW/HW integration and the communication that encourages the system modularity and flexibility*. (3) *middleware design for Edge Computing which rely on a centralized development environment for distributed applications, while the middleware facilitates the integration of the peripheral nodes in the network, and allows automatic remote reconfiguration both SW and HW (FPGA).*
Optimization by parallelization of the 3d elastic Free Form Deformation algorithm
DSV/I2BM/MIRCen - CEA Fontenay-aux-Roses, France (2012)
Master 2, research project
**Keyword**: `Bioinformatic, 3D image registration, image proccessing, Computer vision`
**Skills**: `Python, C/C++, openCV, linux, teamwork`
Working in bioinformatic domain, my work addresses an optimization and parallelisation solution for an elastic 3D Freeform Deformation (FFD) algorithm implemented at MIRCen. The goal is to optimize the 3D mapping of biomedical multimodal mono and inter-subject data whose volume is increasing exponentially.

Jarvis the DYI robot
DYI Robot system for indoor autonomous exploration and navigation
It is one of my hobby project outside of my job.
My goal in this DIY project is to make a low-cost yet feature-rich ROS (Robot Operating System) based mobile robot that allow me to experiment my work on autonomous robot at home.

A web desktop for accessing embedded linux or linux server from browser
**Keywords**: `web OS, web technologies, Web API, UI design, system design`
AntOS is a front-end API that mimics the traditional desktop environment on the web browser. The original purpose of AntOS is to provide visual tools to access and control resource on remote server and embedded linux environment. With its application API and the provided SDK, AntOS facilitates the development and deployment of user specific applications.
