The world of robotics is full of technical terminology that can be confusing for newcomers. This glossary explains the key terms you will encounter when researching home humanoid robots and smart home devices. Bookmark this page for reference as you explore our other content.
A
Actuator
A mechanism that converts energy into motion. In humanoid robots, actuators are the "muscles" that move joints. Modern humanoid robots use electric actuators with position sensing, force sensing, and torque control.
AI (Artificial Intelligence)
Computer systems that can perform tasks that typically require human intelligence. In robotics, AI enables perception, reasoning, and decision-making. Modern humanoid robots use AI foundation models trained on massive datasets.
Alexa
Amazon's voice assistant, used in Echo devices and integrated with thousands of smart home products. The most popular smart home platform by device count.
Autonomy
The ability of a robot to operate without human intervention. Fully autonomous robots can complete tasks independently; semi-autonomous robots require some human guidance.
Auto-Empty Base
A charging station for robot vacuums that automatically empties the dustbin. Modern auto-empty bases can hold 60+ days of debris, enabling months of hands-free operation.
B
Bagless Self-Empty
A self-emptying base design that does not require replacement bags. Uses a permanent container that the user empties periodically. Saves ongoing costs compared to bagged systems.
Bipedal
Walking on two legs. Bipedal locomotion is a defining characteristic of humanoid robots and enables them to navigate environments designed for human bodies.
Bluetooth
A short-range wireless communication protocol. Used in smart home devices for initial setup and some control functions. Limited range makes it less suitable for whole-home automation.
C
Clean Base
iRobot's branded name for their self-emptying base station. Uses disposable bags for hygienic disposal of debris.
Compliance-Based Actuator
A type of actuator that "gives" when it encounters unexpected resistance, similar to human muscles. Inherently safer than rigid actuators. Used in the 1X Neo humanoid robot.
Core Web Vitals
Google's metrics for website user experience: loading performance, interactivity, and visual stability. Important for SEO but not directly related to robotics.
C-Wire (Common Wire)
A wire in HVAC systems that provides continuous power to smart thermostats. Required for some smart thermostat installations.
D
Degrees of Freedom (DoF)
The number of independent axes a robot can move along. A human hand has approximately 27 DoF. Robot hands range from 6 to 16 DoF. More DoF means more dexterous manipulation.
Depth Sensor
A sensor that measures distance to objects, enabling 3D perception. Types include time-of-flight (ToF), structured light, and stereo vision. Essential for robot navigation.
DoF
See Degrees of Freedom.
E
Echo
Amazon's line of smart speakers and displays powered by Alexa. Includes Echo Dot, Echo, Echo Show, and Echo Hub.
Ecosystem
A smart home platform (Alexa, Google Home, Apple HomeKit, SmartThings). Choosing an ecosystem determines which devices work together and which voice assistant you use.
End-Effector
The tool or gripper at the end of a robot arm. For humanoid robots, the end-effectors are typically hands or grippers.
F
Foundation Model
A large AI model trained on vast datasets that can be adapted to many tasks. In robotics, foundation models enable general-purpose manipulation rather than task-specific programming.
Full Self-Driving (FSD)
Tesla's advanced driver assistance system. The AI technology developed for FSD informs Tesla's Optimus robot perception and navigation systems.
G
Google Home
Google's smart home platform, powered by Google Assistant. Integrates with Nest devices and thousands of third-party products.
Gripper
A robotic end-effector designed to grasp objects. Simpler than a full hand, typically with 2-3 fingers. Used in industrial robots; less common in humanoid robots which use articulated hands.
H
HEPA Filtration
High-Efficiency Particulate Air filtration, capturing 99.97% of particles 0.3 microns or larger. Important for allergy sufferers. Found in premium robot vacuums and self-empty bases.
HomeKit
Apple's smart home platform. Known for strong privacy and security. Smaller device ecosystem than Alexa or Google.
Humanoid Robot
A robot designed to resemble and function like a human, with bipedal locomotion and human-like manipulation. The category includes Tesla Optimus, Figure 02, and 1X Neo.
I
Imprint Link
iRobot's technology for coordinating multiple robots. Enables a Roomba to vacuum and then signal a Braava mop to clean the same area.
IoT (Internet of Things)
The network of connected devices in your home, including smart home devices, robots, and appliances. IoT devices can communicate and be controlled remotely.
J-L
LiDAR
Light Detection and Ranging. A laser-based sensing technology that creates precise 3D maps of environments. Used in robot vacuums for navigation and in humanoid robots for spatial awareness.
LIDAR Navigation
Robot navigation using LiDAR sensors. More precise than vision-based navigation, especially in low-light conditions. Used by Shark and ECOVACS robot vacuums.
M
Machine Learning
A subset of AI where systems improve through experience. Modern robots use machine learning to improve task performance over time.
Matter
A unified smart home standard backed by Apple, Google, Amazon, and Samsung. Matter-compatible devices work across ecosystems, reducing fragmentation.
Matrix Clean
Shark's technology for systematic cleaning in a grid pattern, ensuring thorough coverage of each area.
Mop
A robot vacuum accessory that wipes floors with a wet pad. Modern robot mops include self-cleaning features and active scrubbing.
N-P
NEO AI
1X Technologies' in-house AI system for the Neo humanoid robot. Enhanced through partnership with OpenAI.
Nest
Google's line of smart home products, including thermostats, cameras, and smart displays.
Obstacle Avoidance
A robot's ability to detect and avoid objects in its path. AI-powered obstacle avoidance can recognize specific hazards like pet waste, cords, and shoes.
OZMO
ECOVACS' mopping technology. The OZMO roller mop actively scrubs and self-cleans, unlike passive pad mops.
Payload Capacity
The maximum weight a robot can lift or carry. Humanoid robots typically have payload capacities of 20 to 25 kg (44 to 55 lbs).
PrecisionVision
iRobot's AI-powered obstacle avoidance system, found in Roomba j7+ and newer models. Best-in-class obstacle recognition.
R-S
Reinforcement Learning
An AI training method where a system learns by trial and error, receiving rewards for successful actions. Used to train robots in walking, manipulation, and other skills.
Robot Vacuum
An autonomous robot designed to clean floors. The most successful home robot category, with over 50 million units sold annually.
Self-Emptying Base
A charging station that automatically empties a robot vacuum's dustbin. Enables weeks or months of hands-free operation.
Sim-to-Real Transfer
The process of training a robot in simulation and then deploying the trained model on a physical robot. Essential for efficient robot training.
Smart Home
A home equipped with connected devices that can be controlled remotely and automated. Includes lighting, climate, security, and entertainment systems.
SmartThings
Samsung's smart home platform. Excellent integration with Samsung appliances and the Samsung Ballie robot.
Spatial Audio
Audio technology that creates a three-dimensional sound experience. Found in premium smart speakers like Echo Show 8.
T-Z
Thread
