Robot Guide · updated October 2026
What each robot does, its key features, how its maker sells it and what it costs where the maker publishes a price, plus the rules to know before you buy. Every fact links to its source.

This guide is information only, not a listing or an offer. Devdoot™ does not sell these robots yet, and makers are named only to describe their products; they are not partners unless announced. Prices and availability are as published by each maker and can change: check the maker's site before buying. For robots made outside the US, ask the maker to confirm the model's FCC authorization before buying for US use.
Before you buy
Since 28 July 2026, foreign-produced "advanced robotic devices" are on the FCC Covered List: ground robots over 4.4 lb (2 kg) that work at a distance from their operator and have sensors, network connectivity and navigation software, including humanoids, quadrupeds and autonomous mobile robots. Models authorized before then can still be imported, sold and updated (updates are allowed through at least 1 January 2029). New foreign-made models need conditional approval. Fixed industrial and medical arms, drones, vehicles and medical devices are excluded.
Robots that work near people are tested against published safety standards. ISO 13482 covers personal care robots (mobile servant, physical assistant and person carrier robots). UL 3300 covers service, communication, information, education and entertainment robots. ANSI/A3 R15.08 covers industrial mobile robots in workplaces, and ISO 10218 covers industrial robot arms. Ask which standards a robot has been certified to.
The EU Machinery Regulation (EU) 2023/1230 replaces the Machinery Directive and applies from 20 January 2027. It explicitly covers autonomous mobile machinery, including robots. Robots sold in the EU carry CE marking showing the maker's conformity.
Most robots see and hear. If a robot recognises faces or voices, it may collect biometric data, which some laws strictly regulate. Illinois' Biometric Information Privacy Act requires notice and written consent, and delivery robots operating in Chicago have faced class actions under it. In Europe, the GDPR applies. Find out what a robot records, where the data is stored and whether face recognition can be switched off.
A plain-English summary, not legal advice. Check the rules that apply where you will use the robot.
Buyer's checklist
That company handles the warranty, returns and service. Get it in writing.
In the US, ask for the model's FCC authorization. In the EU, look for CE marking.
Robots need on-site support. Ask for the nearest service partner and response times.
Many service robots are sold as a monthly subscription that includes maintenance. Compare the total cost over three years.
Software updates keep a robot safe and secure. Ask how many years of updates are included.
Ask about cameras, microphones, face recognition, cloud storage and how to switch features off.
For example ISO 13482, UL 3300 or ANSI/A3 R15.08, depending on the robot and where it works.
A good robot says when it can't do something safely and hands over to a person rather than guessing. Devdoot™ software is built around that.
