Companion Robots: A Technical Guide for 2026
Companion robots, also known as AI robots, are mobile devices designed for interaction, monitoring, and entertainment within the home. Their functionality relies on a combination of mobile robotics, camera technology, artificial intelligence, and app control. They address specific use cases such as pet supervision, home monitoring, or interactive engagement. The choice of a suitable model depends on your individual requirements for mobility, image quality, and interactive capabilities.
What to Look for When Choosing a Companion Robot
The decision to purchase a companion robot should be based on an analysis of its technical specifications. The following criteria are relevant for making an informed choice:
1. Mobility and Navigation
A robot's ability to move around the home, either autonomously or via remote control, is a core feature. Models with tracks, like the EBO Air 2 Plus, often offer superior all-terrain capability and can overcome obstacles such as carpet edges or low door sills (up to a 15° incline, according to the manufacturer). Wheel-based models are typically more agile on smooth floors. Sensors like 3D-ToF (Time-of-Flight) enable precise spatial mapping and obstacle avoidance.
2. Camera and Audio Quality
As a surveillance robot with a camera, image resolution is crucial. Standards range from 2K (1296p) to 3K. A high resolution allows for the recognition of fine details, even when using digital zoom. For use in low-light conditions, an infrared night vision function is essential. Two-way audio, featuring an integrated microphone and speaker, permits direct communication through the robot.
3. AI Features and Interactivity
Modern devices integrate AI systems for advanced functionality. This can include person and pet detection, automatic object tracking, or voice interaction. Some models, such as the EBO Air 2 Plus or the loona robot, use APIs for large language models (e.g., ChatGPT) to hold conversations or answer questions. For use as an interactive toy robot, features like laser pointers, ball games, or programmable motion sequences are relevant.
4. Connectivity and Control
Control is typically managed via a smartphone app (an app-controlled robot). The connection is established over your home Wi-Fi network. It's important to check whether the device supports 2.4 GHz or also 5 GHz networks. The app serves as the central interface for remote control, the video stream, configuring patrol routes, and managing privacy settings.
5. Battery Life and Charging
A key convenience feature is automatic charging. The robot independently returns to its charging dock when the battery is low. This ensures continuous operational readiness without manual intervention. The battery capacity and charging time determine the length of its autonomous operational periods.
6. Privacy and Data Storage
Since these devices use cameras and microphones, data privacy is a major consideration. Features such as an app-activated privacy mode or the option for local storage of recordings on an SD card give the user control over their data.

Frequently Asked Questions (FAQ)
What is the difference between a companion robot and a stationary surveillance camera? The main difference is mobility. While a stationary camera has a fixed viewing angle, a companion robot can move freely around a room to inspect different areas, actively interact with pets, or follow people through the house. This allows for dynamic and comprehensive monitoring.
How secure is the data captured by an app-controlled robot? Data security depends on the manufacturer and the specific model. Reputable providers use encryption for data transmission. Features like an app-activated privacy mode that deactivates the camera and microphone, as well as the option to store recordings locally on an SD card instead of in the cloud, give the user additional control. It is recommended to review the manufacturer's privacy policy.
Can companion robots serve as electronic pets for children? Models like the loona robot are explicitly designed for interaction and can function as an electronic pet. They offer games, respond to commands, and can be an entertaining companion for older children. However, it is important to follow the manufacturer's age recommendations and to supervise use by younger children, as the devices may contain small parts and have moving components.
