What companion robots are

Companion Robots are robotic systems built for cleaning, delivery, hospitality. They use sensors, actuators, embedded compute, control software, and task logic to act in physical environments.

This reference describes the category rather than a particular commercial product. Capabilities depend on the robot, its tools, software, operating environment and safety design. Product claims should be checked against the manufacturer documentation for the exact model and configuration.

How companion robots work

A companion robots system senses the world using RGB cameras, depth cameras, microphones, touch sensors, IMU, estimates state, plans a task or route, and commands wheeled mobile bases, display modules, small arms, tray lifts. Feedback loops compare the intended motion with what actually happened and trigger corrections, retries, or a safe stop.

Typical applications

cleaning
delivery
hospitality
retail support
companionship

What to verify before deployment

A category description cannot predict performance in a specific workplace. Test the real task, environment and exception cases. Record where the system needs human recovery and confirm that the complete application has an appropriate safety assessment.

Performance drops when sensors face glare, dust, occlusion, deformable objects, poor lighting, water, smoke, or unexpected human behavior.
Hardware maintenance matters because motors, joints, seals, batteries, cables, and sensors degrade.
Most reliable autonomy is narrow and workflow specific.
Integration cost includes training, safety validation, spare parts, maps, network coverage, and support.
Human supervision is often needed for edge cases, recovery, cleaning, charging, or exceptions.
