Projects

Fullstack website

As a personal challenge I created a fullstack website for an automotive service business I'm starting, I used React 18.2 with Typescript for the frontend, nodeJS for the backend (used express for the API development) and MySQL as the database.

Autonomous Vehicle

As my Intelligent Robotics project, I developed with my team an autonomous vehicle using a Puzzlebot with computer vision using the Manchester Robotics Puzzlebot kit, we used a NVIDIA Jetson Nano with ROS, OpenCV for computer vision and darknet for traffic signal detection.

xArm 6 Pick and Place

As my fundamentals of robotics project, me and my team developed a pick and place simulation with the xArm 6 using ROS melodic with MoveIt for the movement planning and Gazebo for the physics simulation of the robotic arm. The robot grabs a cube and places it in its box.

Smart Air Pressure Control

As my advanced embedded systems design project, me and my team developed a pressure controller for the wheels of a tractor for our training partner John Deere, using a STM32H745 and a nodeMCU connected with a CAN bus and other communication protocols and for the air pump its respective power phase.

3D printer temperature controller

As my control systems analysis project, me and my team developed a temperature controller for an extruder using Arduino and PID control and a power phase for the extruder's power supply.

Voice processing & analysis

As my signal and systems analysis project, me and my team developed a script on Matlab to differentiate the voices of different people saying the same sentence.

Washing machine

As my introduction to embedded systems project, I developed the basic functionalities of a washing machine with IoT functionality (remote controlling through WiFi) using an NXP development board.

IoT project

For my IoT Implementation project, me and my team developed the base design of a security system for a house door, with distance detection, movement detection and an MQTT connection to send messages of the status of the sensors.
