Background

As robotics rapidly advances, developing robot applications remains challenging due to the high costs and complexities associated with hardware. Traditionally, testing requires physical robots, making the process expensive and time-consuming. This has led to the development of Virtual Robot Controllers (VRCs), which leverage container-based virtualization to provide a flexible and efficient environment for developing and testing robot applications, offering a cost-effective alternative to physical hardware.

What is the

Virtual Robot Controller?

A Virtual Robot Controller (VRC) is a software-based system designed to emulate the control system functions of a real robot within a virtual environment. Unlike traditional approaches that rely on physical hardware for development and testing, VRCs enable developers to fully simulate and manage a robot's behavior in a software-defined space. The primary uses of a virtual controller include.
Development and Testing
VRCs offer a safe, controlled environment for developing and testing robotic applications. Developers can simulate a robot's behavior across various scenarios to refine algorithms, optimize performance, and debug issues without risking damage to actual hardware.
Education and Training
VRCs are widely used in educational settings to train students and professionals in robotics. The virtual environment provides hands-on experience in robot control and programming, eliminating the need for costly physical robots.

Why do we need

Virtual Robot Controller?

Virtual Robot Controllers (VRCs) are essential because they offer a cost-effective, scalable, and safe alternative to physical robots. VRCs allow developers to simulate and test robotic applications in a virtual environment, reducing the need for expensive hardware and minimizing risks. They also accelerate development by enabling rapid iteration, leading to faster innovation and deployment of new robotic solutions. Additionally, VRCs offer enhanced scalability through cloud integration, enabling the management of large-scale robotic operations without the limitations of physical hardware.
Features

Structure of VRC

The Virtual Robot Controller (VRC) provides a scalable and flexible environment for developing and managing robot applications through container-based virtualization. It operates within a cloud infrastructure, using orchestration platforms like Kubernetes to deliver its functions as a SaaS (Software as a Service) model. The key structural components of VRC are as follows.
Interface Layer
Frontend Server Machine
This server provides a web-based graphical user interface (GUI) that allows users to manage and control virtual robot controllers easily. The GUI simplifies interaction with the VRC, ensuring seamless operation and configuration.
Core Layer
Main Server Machine
Control Server
Manages core operations of the VRC, coordinating the deployment and execution of virtualized controllers within the cloud environment.
Management Functions
Responsible for system management, including monitoring, resource allocation, and task scheduling.
Image Store
Stores pre-configured virtual robot controller images, such as TERMINAL and Karajan, for user deployment and management.
Orchestration Platform
Kubernetes Integration
Manages the deployment, scaling, and operation of VRC across multiple worker machines, ensuring the system can handle large-scale operations and multiple controllers simultaneously.
Worker Machines
Dedicated User Spaces
Each worker machine hosts dedicated user spaces where virtualized controllers operate. These isolated environments allow users to run multiple virtual robot controllers efficiently without interference.
Network Connectivity
Worker machines are networked with the main server and each other, enabling real-time communication and synchronization. Additionally, they execute simulated robots, providing real-time feedback and interaction over the network.
Robots in Simulators
Execution via Worker Machines
Simulated robots operate within dedicated user spaces on worker machines. These simulations occur over the network, allowing for accurate testing and development of robot applications in a controlled virtual environment.

Workflow of VRC

The operational workflow of VRC outlines the steps users take to configure, deploy, and manage virtual robot controllers within the system. This workflow is designed to be intuitive, ensuring users can optimize their robotic operations seamlessly.
Server Connection
Connect to the Server
Users connect to the VRC system through the internet, accessing its cloud-based infrastructure.
User Authentication
Login
Users log in using their credentials, ensuring secure access and providing the necessary permissions to manage virtual robot controllers.
VRC Management
Create/Destroy/Run/Pause VRC
Users can create, destroy, run, or pause virtual robot controllers as needed. The VRC system offers a simple interface for managing these operations, allowing for flexible and efficient control of robot applications.
Application Development
Make Robot Applications
Once configured, users can develop robot applications using the provided environment. Simulated robots, executed via worker machines, allow for comprehensive testing and refinement of robot behaviors and control algorithms in a risk-free, virtual setting.
