Summary
🤩
Rockstar🎓
Top SchoolGuilhem Saurel is a research engineer in Toulouse with 16 years of experience at the intersection of robotics, signal processing and systems engineering, currently based at LAAS-CNRS. He holds engineering and PhD-level training in electronics and robotics and has applied that background to both academic research and practical integrations, from FPGA memory-extension hardware to IoT modem integrations. A prolific contributor to open-source robotics and tooling—helping pinocchio’s inertia modeling, refining Crocoddyl’s optimal-control costs, and improving fish-shell completions—he blends deep numerical understanding with pragmatic back-end and DevOps skills. His work shows attention to reproducible results and testing, having added unit tests and Python bindings across projects. Notably, he adapts solutions for real-world variability (e.g., version-dependent completions for systemd) rather than one-size-fits-all fixes. He combines research rigor with hands-on engineering to move algorithms from theory into reliable, tested code.

Mar 2016 - Nov 2022
A fast and flexible implementation of Rigid Body Dynamics algorithms and their analytical derivatives
Role in this project:
Back-end Developer & Test Automation Engineer
Back-end Developer & Test Automation EngineerContributions:65 reviews, 164 commits, 89 PRs in 6 years 10 months
Contributions summary:Guilhem contributed significantly to the Pinocchio library, specifically focusing on the `Inertia` class and related functionalities. They implemented new methods for creating `Inertia` objects from different shapes (ellipsoid, cylinder, box) and integrated these features within the Python bindings. Furthermore, the user fixed test cases to ensure the correctness and reliability of the inertia calculations. They also addressed Python code style issues and integrated unit tests using a framework.

Crocoddyl is an optimal control library for robot control under contact sequence. Its solver is based on various efficient Differential Dynamic Programming (DDP)-like algorithms
Role in this project:Back-end Developer
Back-end DeveloperContributions:18 releases, 39 reviews, 164 commits in 3 years 9 months
Contributions summary:Guilhem primarily contributed to refactoring the codebase, specifically by merging branches and reverting commits to align with the refactor branch. They modified core cost function models, demonstrating familiarity with the underlying mathematical structures and algorithms used in optimal control and robotics, as well as unit tests for the system. The user also contributed to the codebase by changing source code for the existing models like CostModelFrameTranslation.
