TypeScript for Robotics Programming


Using TypeScript for robotics programming allows you to build applications that control and interact with robots. In this guide, we'll introduce TypeScript for robotics programming and provide a basic example using TypeScript and the Robot Operating System (ROS) library, which is commonly used in robotics development.


Before you begin, make sure you have the following prerequisites:

  • Node.js: You can download it from https://nodejs.org/
  • TypeScript: Install it globally with npm install -g typescript
  • Robot Operating System (ROS) installed and configured on your robot or simulator

Getting Started with TypeScript for Robotics Programming

Let's create a basic example of a TypeScript application that interacts with a robot through the Robot Operating System (ROS).

Step 1: Set Up Your Project

Create a new directory for your project and navigate to it in your terminal:

mkdir robotics-program
cd robotics-program

Step 2: Initialize a Node.js Project

Initialize a Node.js project and answer the prompts. You can use the default settings for most prompts:

npm init

Step 3: Install Dependencies

Install the required dependencies, including TypeScript and any ROS-related packages you may need for your robot:

npm install typescript --save

Step 4: Create TypeScript Configuration

Create a TypeScript configuration file (tsconfig.json) in your project directory:

"compilerOptions": {
"target": "ES6",
"outDir": "./dist",
"rootDir": "./src"

Step 5: Create TypeScript Code

Create a TypeScript file (app.ts) for your robotics program:

// src/app.ts
// Import necessary ROS packages and libraries
import * as ROSLIB from 'roslib';
// Initialize ROS connection
const ros = new ROSLIB.Ros({
url: 'ws://localhost:9090', // Replace with your ROS server URL
ros.on('connection', function () {
console.log('Connected to ROS server.');
ros.on('error', function (error) {
console.error('Error connecting to ROS server:', error);
ros.on('close', function () {
console.log('Disconnected from ROS server.');
// Define your robot control logic here
function controlRobot() {
// Example: Publish a message to a robot topic
const cmdVel = new ROSLIB.Topic({
ros: ros,
name: '/cmd_vel',
messageType: 'geometry_msgs/Twist',
const twist = new ROSLIB.Message({
linear: {
x: 0.2,
y: 0,
z: 0,
angular: {
x: 0,
y: 0,
z: 0.1,
// Call the controlRobot function to send commands to the robot

Step 6: Compile and Run Your TypeScript Code

Compile your TypeScript code using the TypeScript compiler and run your robotics program:

node dist/app.js


This basic example demonstrates how to use TypeScript for robotics programming with ROS. In a real robotics project, you can implement more complex control logic, interact with various sensors and actuators, and perform tasks such as autonomous navigation or object manipulation. TypeScript helps ensure your code is maintainable and well-structured as your robotics application becomes more sophisticated.
