Overview

In this hand-on workshop, you’ll learn the fundamentals of integrating object detection into a mobile robot running on a ROS/Jetson framework. After developing your code in a Gazebo simulation environment, you’ll deploy it to the physical robot for testing.

You’ll start with an overview of the Robot Operating System(ROS) and its associated architecture. Then, you’ll build a node for simple movement of the robot using the development workflow: simulate, develop, and deploy. You’ll proceed to integrate image recognition and object detection deep neural network (DNN) models, including an exploration of how to build your own models with DIGITS. You’ll verify the robot’s behavior in simulation and finally deploy the project to a Jetson/ROS robot.

Throughout the workshop, you’ll get hands-on simulation and coding experience using a live GPU-accelerated environment. At the end, you’ll have access to additional resources to design and deploy Jetson-based applications on your own.

Prerequisites

Experience with deep neural networks (specifically variations of CNNs) and intermediate-level experience Python. Knowledge of Linux and C++ is helpful but not required.

Course Outline

Introduction to ROS Robot Control

  • System overview
  • ROS and Gazebo
  • Coding & testing in simulation

Work with ROS nodes and topics on a cloud desktop to code and run robot movement in a Gazebo simulation.

Deploy to the Robot

  • Deploy and test

Deploy your code to the physical robot and test it in the real world.

ROS Integration of Image Recognition

  • Inference on the robot
  • Training with DIGITS
  • Coding & testing with ROS bags

Learn to integrate inference with ROS nodes. You’ll write code to parse classification messages and test with RSO bags on the desktop.

ROS Integration of Object Detection

  • Inference on the robot
  • Training with DIGITS
  • Coding & testing with ROS bags and Gazebo simulation

Combine what you’ve learned about control and inference integration to build a ROS node that moves toward an object it identifies autonomously.

Deploy Object Detection control node to the Robot

  • Deploy and test

Deploy your code to the physical robot to autonomously find objects.
