What Is Robotics Programming?
Robotics programming connects software with the physical behavior of a robot. A program may read sensor data, calculate a path, control motors, detect objects, or coordinate several actions to complete a task.
The software used depends on the type of robot and the application. A wheeled robot may require software for navigation and mapping, whereas an industrial robotic arm may rely on motion-planning and offline programming tools.
Robotics programming can therefore range from relatively simple scripts to complex systems that combine perception, planning, control, simulation, and hardware interfaces.
How Does Robotics Programming Work?
A simplified robotics software workflow can involve sensors, perception, decision-making, motion planning, control, and actuators.
For example, a mobile robot could use a camera or lidar to collect information about its surroundings. Software can process that information, determine what the robot should do, generate a path, and send commands to the robot’s motors.
Real systems often contain many separate software components rather than one large program. ROS 2 provides a framework that allows these components to communicate and operate together.
For a deeper explanation of ROS 2, see our guide to Robot Operating System (ROS).
Which Programming Languages Are Used in Robotics?
Python
Python is widely used in robotics because it is relatively easy to write and has a large ecosystem of libraries.
It is useful for:
- Prototyping
- Robotics scripts
- Testing
- Computer vision
- Data processing
- Machine learning
- Working with robotics frameworks
Python is especially useful when development speed is more important than maximum execution performance.
C++
C++ is widely used when robotics software needs high performance and precise control over system resources.
It is commonly used for:
- Robot control software
- Motion planning
- Perception systems
- Real-time applications
- High-performance robotics libraries
- ROS 2 applications
C++ is more complex to learn than Python, but it can be important for production robotics systems where performance matters.
C
C is also used in robotics, particularly for embedded systems and microcontrollers. It can be useful when software needs direct interaction with hardware and limited computing resources.
MATLAB
MATLAB is used in robotics for algorithm development, modeling, simulation, control, and testing. MathWorks’ Robotics System Toolbox provides tools for robot modeling, kinematics, dynamics, path planning, localization, motion control, and simulation.
Other Languages
Other languages can also appear in robotics projects, depending on the hardware and software stack.
The best language therefore depends on what the robot needs to do rather than on one universal robotics language.
What Software Is Used for Robotics Programming?
Robotics programming usually involves several types of software rather than a single application.
Robotics Frameworks
A robotics framework provides tools for connecting software components and developing robot applications.
ROS 2 is a robotics framework used to build applications from multiple communicating software components. Developers can use languages such as C++ and Python with ROS 2.
ROS 2 provides a middleware layer that allows different robotics software components to communicate. DDS/RTPS has been a major part of its communication architecture, while ROS 2 can also work with other middleware implementations.
Robot Simulation Software
Simulation software allows developers to test robot behavior in a virtual environment before using physical hardware.
Common options include:
- Gazebo
- NVIDIA Isaac Sim
- Webots
- RoboDK
NVIDIA Isaac Sim is an open-source reference framework for robotics simulation, testing, and synthetic data generation in physically based virtual environments. It can also connect with ROS and ROS 2.
Webots is an open-source, multi-platform robot simulator used for modeling, programming, and simulating robots.
Robot Programming and Offline Programming Software
Industrial robots can also be programmed with dedicated software that allows engineers to create and test robot programs.
RoboDK is used to simulate industrial robot arms and create programs for them without running the robot on the production floor. It provides an API for languages including Python, C#/.NET, C++, and MATLAB, and supports program generation for robots from numerous manufacturers.
Offline programming is useful because a robot program can be prepared and tested away from the production floor.
Robotics Development Toolboxes
Some platforms provide libraries and algorithms rather than acting as complete robot programming environments.
MathWorks Robotics System Toolbox provides tools for robot modeling, kinematics, dynamics, path planning, localization, motion control, collision checking, simulation, and other robotics development tasks.
What Are the Main Types of Robotics Programming?
Robotics programming covers several different tasks.
Motion Programming
Motion programming controls how a robot moves.
For a robotic arm, this can involve specifying joint positions, Cartesian positions, trajectories, speeds, and other movement parameters.
Control Programming
Control software determines how the robot responds to commands and sensor feedback.
It can be used to maintain position, velocity, or other physical states while the robot performs a task.
Perception Programming
Perception software processes information from sensors such as cameras, lidar, and depth sensors.
Applications can include:
- Object detection
- Image processing
- Localization
- Environment mapping
- Distance measurement
Navigation Programming
Navigation software helps mobile robots determine where they are and how to reach a destination.
It can combine mapping, localization, path planning, obstacle avoidance, and motion control.
Task Programming
Task-level programming defines what the robot should accomplish.
For example, an application could tell a robot to pick up a component, move it to another location, and place it into a fixture.
Robotics Programming vs. Robot Programming
The terms are closely related, but they can have different meanings.
Robotics programming is the broader field. It can include software development for perception, navigation, simulation, control, planning, and robot applications.
Robot programming often refers more specifically to creating instructions that make a particular robot perform a task.
For example, developing a ROS 2 navigation system is robotics programming. Creating an offline program for an industrial arm to weld a particular path is robot programming.
The distinction is not absolute, and the terms are often used interchangeably.
Robotics Programming With ROS 2
ROS 2 can provide the software framework that connects different parts of a robotics application.
A project might contain:
- A camera node
- A perception node
- A planning node
- A controller
- A hardware interface
- Visualization tools
These components can communicate through ROS 2 mechanisms such as topics, services, and actions.
ROS 2 also supports C++ through rclcpp and Python through rclpy.
This makes ROS 2 useful when a robotics project needs multiple software components to work together rather than relying on one standalone program.
Robotics Programming With Simulation
Simulation is an important part of modern robotics development because it allows software to be tested without constantly using physical hardware.
A typical workflow can look like this:
- Create or import a robot model.
- Build a virtual environment.
- Add sensors and other equipment.
- Write the robotics software.
- Run the robot in simulation.
- Test movement and behavior.
- Identify problems.
- Improve the software.
- Test the system on physical hardware.
NVIDIA Isaac Sim can import robot and CAD-related data, configure physics and sensors, generate synthetic data, and support software-in-the-loop and hardware-in-the-loop testing. It can also connect to ROS and ROS 2.
RoboDK focuses on industrial robot simulation and offline programming. It can simulate robot cells, check paths, and generate programs for supported robot controllers.
Software Used for Robotics Programming
There is no single robotics programming tool for every project. The right choice depends on the robot, programming requirements, simulation needs, and hardware.
| Software | Common use |
|---|---|
| ROS 2 | Building modular robot applications |
| RoboDK | Industrial robot simulation and offline programming |
| MATLAB Robotics System Toolbox | Robotics algorithms, modeling, simulation, and testing |
| NVIDIA Isaac Sim | Robotics simulation, testing, and synthetic data |
| Webots | Robot simulation and development |
RoboDK is particularly focused on industrial robots and supports a large range of robot manufacturers and controllers.
NVIDIA Isaac Sim is aimed at simulation, testing, synthetic data generation, and robotics development, while Webots provides a simulator for developing and testing robotic applications.
