Engineering Projects
Reconfigurable Parallel Robot & Bistable Gripper
The Challenge
Develop from scratch a reconfigurable parallel robot (4-DOF) integrating an end-effector capable of adapting to any object shape via purely mechanical control.
The Solution
- Mathematical Modeling: Kinematic, singularity, and dynamic analysis of the system, validated by a digital twin using MATLAB/Simscape.
- Mechanical Innovation: Design of a monolithic gripper integrating a "cam-follower" bistable mechanism (pen-style) for dual action (locking/unlocking at physical limit).
- Soft Robotics: Jaws equipped with Fin Ray effect technology, deforming to grip complex objects without force sensors.
Result
A functional 3D-printed prototype (SLS powder), validating the integration of compliance for advanced Pick & Place operations.

Autonomous Cable Theft Detection Device
The Challenge
Design a fully autonomous IoT system capable of detecting cable theft on power grids and transmitting a long-range alert, operating in a harsh outdoor environment.
The Solution
- Electronics & IoT: Architecture based on a STM32 (Nucleo WL55JC1) with LoRaWAN communication and solar energy harvesting.
- Embedded Intelligence: Detection via ultra-low-power accelerometer (wake-up on shock) and indirect current verification via 3-axis magnetometer.
- Mechanical Design: Waterproof hybrid enclosure (metal for robustness, plexiglass for RF/solar transparency) with 3D-printed ASA mounts.
Result
A functional, waterproof, and communicating prototype, validating the technological approach for autonomous remote detection.

TraceBot Gripper & Compliant Mechanisms
The Challenge
As part of the European TraceBot project, redesign a cable-driven robotic finger to reduce its inertia, simplify assembly, and maintain perfect "mechanical transparency" (10N force).
The Solution
- Pivot Elimination: Replacement of mechanical joints with TPU 3D-printed compliant mechanisms, providing natural elastic return.
- Gyroid Structure: Integration of an isotropic mathematical lattice (gyroid) into the core to optimize grip and allow homogeneous deformation.
- Custom Test Bench: Hardware and software design (Arduino/C++) of a dynamic fatigue test bench.
Result
A compliant joint experimentally validated for over 100,000 bending cycles, featuring a drastically simplified and lighter architecture.

Smart Gripper & Robotics Reliability
The Challenge
On a high-speed automotive production line, a 6-axis robotic arm suffered from a high failure rate when clipping plastic fasteners. Objective: eradicate defects without halting production.
The Solution
- Mechanical Redesign: Machining of a new monolithic steel finger integrating a chamfer to absorb positioning errors (+/- 1mm tolerance).
- Proof of Concept (IoT): Replacing expensive vision systems with embedded dynamic analysis. Developed a custom Wi-Fi module (Arduino, MPU-6050) mounted on the arm.
- Signal Processing: Reliable detection of the fastener's mechanical "click" by isolating a specific acceleration peak.
Result
Drastic drop in placement errors. Awarded the "Improvement Idea of the Month" prize by plant management.
