Glossary

Every field builds its own wall of jargon. This is ours — torn down. 39 terms, defined in one or two sentences, each linked to the brief that explains the full mechanism.

A

Actuator

The motor or muscle of a robot — the component that converts control signals into physical motion.

Related brief →

AI Agent

An autonomous LLM-powered system that plans multi-step tasks, keeps memory, and calls external tools.

Related brief →

Attention Mechanism

A method that lets a model weigh the relevance of every token in a sequence against every other, regardless of distance.

Related brief →
B

Brain-Computer Interface

A system that decodes neural signals directly into commands, bypassing muscles and speech entirely.

Related brief →

Byte-Pair Encoding

The tokenization algorithm that breaks raw text into reusable sub-word units before a model reads it.

Related brief →
C

Chiplet

A modular die that is packaged together with others, trading monolithic silicon for flexible yields.

Related brief →

Collaborative Robot

A robot designed to share a workspace with people, using force limits and sensors instead of cages.

Related brief →

Convolutional Neural Network

A vision architecture that scans images with small learned filters to detect edges, textures, and objects.

Related brief →
D

Denavit–Hartenberg Parameters

The standard four-number notation that describes the geometry of each joint in a robotic arm.

Related brief →

Dendrite

A needle-like lithium structure that can pierce battery separators; solid-state electrolytes aim to stop it.

Related brief →

Diffusion Model

An image generator that learns to reverse a gradual noising process, sculpting pictures out of static.

Related brief →
E

Edge AI

Running inference directly on phones, sensors, and devices instead of in a distant data center.

Related brief →

Embedding

A high-dimensional vector that captures the meaning of a word, image, or document as a point in space.

Related brief →

EUV Lithography

Extreme ultraviolet printing of chip patterns at 13.5nm wavelength, required for the densest modern nodes.

Related brief →
F

FinFET

A transistor whose gate wraps around a vertical fin of silicon, improving control over current flow.

Related brief →
G

GAAFET

Gate-all-around transistor architecture that surrounds the channel on all sides for even tighter control.

Related brief →

GNSS Localization

Satellite positioning fused with other sensors so a vehicle knows where it stands on the road.

Related brief →
H

HD Map

Centimeter-accurate road maps that autonomous vehicles use as a prior for perception and planning.

Related brief →

High-Bandwidth Memory

Memory stacked vertically and connected by over a thousand wires, feeding data to AI accelerators.

Related brief →
I

Inverse Kinematics

The math of working backward from a desired hand position to the joint angles that reach it.

Related brief →
K

Kalman Filter

A recursive algorithm that fuses noisy sensor readings into a single best estimate of position or state.

Related brief →
L

Large Language Model

A transformer-based network trained on trillions of tokens to predict — and generate — human language.

Related brief →

Latent Space

The compressed geometric space where a generative model represents and manipulates concepts.

Related brief →

LiDAR

Pulsed laser ranging that builds precise 3D point clouds of the surrounding environment.

Related brief →
M

Maglev

Magnetic levitation that removes wheel contact and friction, letting trains cruise at aircraft speeds.

Related brief →

Multimodal Model

A single model that jointly understands text, images, and audio through shared embeddings.

Related brief →
N

NPU

A processor specialized for the matrix multiplications that dominate neural network workloads.

Related brief →
P

Photolithography

The light-based printing process that transfers circuit patterns onto silicon wafers, layer by layer.

Related brief →

Photonic Computing

Computing with light instead of electrons, promising bandwidth and speed without resistive heat.

Related brief →
Q

Qubit

The quantum bit, which can hold superpositions of 0 and 1 and entangle with other qubits.

Related brief →
R

Retrieval-Augmented Generation

Grounding an LLM in documents retrieved from a vector database before it answers.

Related brief →

RLHF

Reinforcement learning from human feedback — the alignment stage that makes models helpful and safe.

Related brief →
S

Sim-to-Real Transfer

Training robot skills in simulation and successfully moving them onto physical hardware.

Related brief →

Superposition

A qubit's ability to exist in a weighted combination of states until measured.

Related brief →
T

Tokamak

The donut-shaped magnetic confinement vessel used to hold fusion plasma at millions of degrees.

Related brief →

Tokenization

Splitting raw text into the small units — tokens — that a language model actually processes.

Related brief →
V

V2X Communication

Vehicle-to-everything messaging — car to car, car to infrastructure, car to network.

Related brief →

Vector Database

A store built to search millions of embeddings by semantic similarity rather than exact keywords.

Related brief →
W

Wafer

The ultra-flat disc of purified silicon on which thousands of chips are printed at once.
