A differential drive robot is controlled using ROS2 Humble running on a Raspberry Pi 4 (running Ubuntu server 22.04). The vehicle is equipped with a raspberry pi camera for visual feedback and an RPlidar A1 sensor used for Simultaneous Localization and Mapping (SLAM), autonomous navigation and obstacle avoidance.

PCA9685 full function driver library for general MCU and Linux.

This software is a devLib extension to wiringPi http://wiringpi.com/ and enables it to control the Adafruit PCA9685 16-Channel 12-bit PWM/Servo Driver http://www.adafruit.com/products/815 via I2C interface.

Driver for the PCA9685 12-bit PWM driver using STM32Cube HAL

This is to connect a LED-Lamp (with up to 16 channels and 4096 steps resolution per channel) to a mqtt server

A 6 degree of freedom (DOF) robot arm is controlled using the ROS2 robotic manipulation platform, MoveIt 2. The ROS2 Humble version of MoveIt 2 is used, which runs in a Docker container on an Nvidia Jetson Nano board. The robot arm is equipped with an Intel Realsense D415 depth camera used to detect ArUco markers on objects to be picked up.

Robotic arm to be printed on the 3D printer controlled by Raspberry Pi, PCA9685 for servomotors and programmed in Python.

Control LEDs connected to a micro controller using pulse-width modulation.

ROS2 Controller for the Adafruit 16 channel PWM servo I²C board, hat and similar PCA9685 based boards, provides absolute proportional PWM control as well as supports geometry_msgs/Twist.
