Mechanical Dimensioning

Load-Lifting System Design

Complete dimensioning of a load-lifting machine (lève-charge) designed to elevate heavy loads through a mechanical transmission chain. A large-scale project split into two lots, each covering distinct sub-systems.

The system integrates a screw-nut mechanism for vertical lifting, combined with a belt-pulley transmission and a speed reducer. All components were dimensioned according to ISO standards and designed in PTC Creo.

Ping-Pong Ball Launcher — PCB Design

Full electronic card designed on Proteus for a ping-pong ball launching robot. The custom circular PCB is built around an ATmega microcontroller and integrates all the control logic for the robot's actuators.

The board manages motor drivers, sensor interfaces and power regulation, all routed on a compact circular form factor matching the robot's chassis geometry.

LED Ring — Moore & Mealy State Machine

Design and implementation of an LED ring controller using finite state machine (FSM) theory. The system was modeled and implemented using both Moore and Mealy machine architectures, controlling sequential LED lighting patterns.

The project required formalizing state transition diagrams, encoding states in logic, and implementing the circuit to drive the LED ring with distinct behavioral outputs for each machine type.
