RoboticsExplainer
How a robot turns sensor readings into movement.
Follow the loop from sensing and localization to planning and control, and learn why timing and coordinate frames matter as much as a good-looking route.
THE EXPLAINER LIBRARY
Understand how technology works.
Clear explanations, real examples, and the evidence behind new ideas.
AIExplainer
How RAG gives an AI something to look up.
Understand retrieval-augmented generation, embeddings and citations with a worked example—and see why finding a source is not the same as proving an answer.
EnergyExplainer
Battery capacity, energy and power are three different questions.
Learn what happens inside a rechargeable cell, how amp-hours differ from watt-hours, and how to read a battery headline without mixing material and pack results.
FOLLOW THE MECHANISM
A robot needs more than a route.
A doorway, a map and a moving obstacle reveal why sensing, localization, planning and control have different jobs.
- What was actually observed?
- Which position is an estimate?
- How does the plan become motion?
Keep following the question.

Keep a good question.
Check the measurement, conditions and missing evidence before extending a claim.
A SMALL, USEFUL VOCABULARY
Useful terms, clearly explained.
Retrieval-augmented generation (RAG)
A workflow that retrieves relevant information and supplies it as context for a generated answer. The retrieved evidence and the answer still need checking.
Read the explanation →Embedding
A numerical representation used to compare information, often by semantic similarity. Similarity is a retrieval signal, not proof that a statement is true.
Read the explanation →Localization
Estimating where a robot is within a reference frame or map. It differs from simply measuring recent movement.
Read the explanation →Costmap
A representation used by a navigation system to assign movement costs to regions. Its values describe the model, not every possible real-world hazard.
Read the explanation →Watt-hour (Wh)
A unit of energy. A watt is a unit of power: the rate of using or supplying energy. Keeping them separate makes battery comparisons clearer.
Read the explanation →Waveguide
A structure that confines and directs a wave. In a photonic chip, it helps guide light through the optical circuit.
Read the explanation →Data rate and latency
Data rate describes how much information can be carried per unit time. Latency describes delay; increasing the rate does not eliminate propagation time.
Read the explanation →Biohybrid actuator
An engineered mechanism in which living cells contribute force or motion. Tissue, structure, stimulus and support conditions are all part of the system.
