1. Introduction & Overview
What are Companion/Service Robots?
Companion/Service Robots are autonomous or semi-autonomous robots designed to assist humans in daily activities, either at home, in healthcare, retail, or industrial settings. Unlike industrial robots (which focus on manufacturing tasks), companion/service robots interact directly with people, providing social, healthcare, hospitality, and personal support functions.
Examples include:
- Healthcare service robots (assisting elderly patients, medication delivery)
- Retail robots (guiding customers, inventory assistance)
- Household companion robots (vacuum cleaners, elder-care assistants, pet robots)
- Hospital service robots (transporting supplies, disinfecting rooms)
History & Background
- 1960s–1970s: First service robots appeared in hospitals for delivering items.
- 1980s: Companion robots in research labs (e.g., MIT’s Kismet social robot).
- 1990s: Sony introduced AIBO robotic pet.
- 2000s: Widespread household robots like iRobot Roomba gained popularity.
- 2010s: AI-powered service robots such as Softbank’s Pepper began interacting with customers in retail and banking.
- 2020s onwards: Companion/service robots integrated with cloud robotics, IoT, and RobotOps platforms for lifecycle management.
Why is it Relevant in RobotOps?
RobotOps (Robotics Operations) is the DevOps-inspired approach to managing the lifecycle of robots, including:
- Deployment
- Monitoring
- Scaling
- Updating software/firmware
- Ensuring safety and compliance
Companion/service robots require continuous updates, security patches, anomaly detection, and remote monitoring—making RobotOps essential for reliability and trustworthiness.
2. Core Concepts & Terminology
| Term | Definition | Example in Service Robots |
|---|---|---|
| HRI (Human-Robot Interaction) | Methods for communication between humans and robots | Voice recognition in Alexa-enabled robots |
| Telepresence | Remote presence through robots | Hospital telepresence robots for doctors |
| Autonomous Navigation (SLAM) | Robot’s ability to map and move in environments | Hospital robot navigating hallways |
| Edge AI | AI computations on robot hardware | Facial recognition for elderly care robot |
| Fleet Management | Managing multiple robots remotely | Retail chain monitoring all customer service robots |
How it fits into the RobotOps Lifecycle
- Plan: Define service tasks (cleaning, guiding, assisting)
- Build: Develop robot software stack (AI, NLP, navigation)
- Deploy: Rollout firmware/ML models to robots
- Monitor: Track robot health, task success rate, anomalies
- Automate: Enable self-healing, remote updates
- Scale: Expand to multiple robots in different locations
3. Architecture & How It Works
Key Components
- Hardware – Sensors (LIDAR, cameras), actuators, wheels/arms
- Software stack – OS (ROS/ROS2), navigation system, AI models
- Cloud integration – For updates, analytics, and monitoring
- Communication layer – MQTT, WebSockets, or 5G
- RobotOps layer – CI/CD pipelines, monitoring, alerting, logging
Internal Workflow
- User interacts (voice, app, gesture)
- Robot processes command via AI/NLP
- Navigation & path planning module calculates route
- Task executed (e.g., fetch item, answer question)
- Logs sent to RobotOps monitoring system
- Updates/patches deployed remotely via cloud

Integration Points with CI/CD or Cloud Tools
| RobotOps Tool | Purpose in Companion/Service Robots |
|---|---|
| GitHub Actions / GitLab CI | Automating robot firmware/AI model deployment |
| Kubernetes + ROS2 | Orchestrating multiple service robots in fleets |
| Prometheus + Grafana | Monitoring robot health (battery, CPU, task success) |
| AWS RoboMaker / Azure Robotics | Cloud simulation and fleet management |
| ELK Stack | Logging robot activity for audits |
4. Installation & Getting Started
