From the project

ROS Noetic mobile manipulator: differential-drive chassis + 5-DOF arm with MoveIt!, Gazebo simulation, real-time C++ hardware interface, and custom KiCad power electronics

A complete, production-grade robotics system integrating a mobile base and a 5-DOF manipulator, developed under ROS Noetic on Ubuntu 20.04.

This repository contains the entire development stack: - Custom hardware designs (KiCad) for servo power distribution and current limiting - Low-level embedded drivers in C++ (UART-based motor control, PWM generation, BLDC/servo feedback) - ROS hardware interface with real-time joint state publishing and trajectory execution - MoveIt! motion planning (OMPL, CHOMP, STOMP pipelines) - Full Gazebo simulation and RViz visualization - Comprehensive…
