Study Notes
Robot Programming
- Need for a generalized robot programming platform
- History of the Robot Operating System (ROS)
- ROS Basics
- ROS Demo
Operating System
- An OS provides standardized interfaces facilitating hardware-agnostic software application
- OS sits between hardware and user/application
Robotics in the 2000s
- Birth of the Robot Operating System (ROS)
What is ROS?
- Open-source pseudo-operating system (sits on top of standard OS)
- Collection of design/development tools for programming robots (Simulation & visualization tools)
- Distributed architecture – not just communication between processes but also machines
- Data Handling and Analysis
- Language-independent – C++, Python (& Java, Lisp, MATLAB, etc.)
- Implementation of standard tools, and interfaces to different problems with the intention of re-usability
ROS Overview
- Key ROS functionality
- Tools for configuring, starting, introspecting, debugging, visualizing, logging, testing, and stopping distributed computing systems
- Verified implementations of useful robot functions, focused on manipulation, mobility, and perception
- Infrastructure designed to support the quick and easy construction of distributed computing systems
ROS Adoption
- According to ABI Research, roughly 55% of the world's robots will include a ROS package by 2024
ROS Basic Graph Structure
- ROS Master: handles distributed communications connections, registers and looks up ROS resources
- ROS Node: a process that performs computation, e.g., obstacle avoidance node adapts motor speed proportionally to Laser Displacement Data
- ROS Topic: named bus over which nodes exchange messages, asynchronous publish/subscribe model
ROS Limitations
- ROS 1 limitations: tied to OS development (Ubuntu), no real-time performance guarantee, not suited to multiple robots, assumes good network connectivity & no security, and can be too bloated for small robot applications
Future of ROS
- ROS 2 promises to address ROS 1 limitations
