History of Robotics – Structured Overview
1. Foundations (Ancient – 19th Century)
| Era |
Milestones |
Key Figures / Cultures |
| Ancient Myths & Automata |
• Tales of mechanical beings (e.g., Talos of Crete, Hephaestus’s golden assistants)
• Early “automata” used in temples and festivals |
Greek mythology, ancient Egypt |
| Classical Antiquity |
• First known programmable device – Hero of Alexandria (c. 10 CE) built a steam‑powered automaton that opened temple doors |
Hero of Alexandria |
| Middle Ages |
• Mechanical clocks with moving figures; early self‑acting devices in Islamic world (e.g., Al‑Jazari) |
Al‑Jazari (1206 CE) – “The Book of Knowledge of Ingenious Mechanical Devices” |
| Renaissance |
• Leonardo da Vinci’s sketches of a humanoid “mechanical knight” (1495) |
Leonardo da Vinci |
| Industrial Revolution |
• Development of precision metalworking, steam power, and early programmable looms (e.g., Jacquard loom, 1804) – the first use of punched cards for control |
Joseph Marie Jacquard |
2. Birth of Modern Robotics (20th Century)
2.1 Early Concepts & Terminology
| Year |
Event |
Significance |
| 1920 |
Karel Čapek’s play “R.U.R.” (Rossum’s Universal Robots) |
Introduced the word “robot” (from Czech robota = forced labor). |
| 1939 |
Isaac Asimov’s Three Laws of Robotics (first published 1942) |
Provided a philosophical framework that still influences robot ethics. |

Notable Features |
| 1948 |
The “Elektro” |
Westinghouse |
First humanoid robot shown on TV; could walk, talk, smoke. |
| 1954 |
Unimate (prototype) |
George Devol & Joseph Engelberger |
First industrial robot; used a programmable magnetic drum for control. |
| 1961 |
Unimate 001 installed at General Motors (Fremont, CA) |
Engelberger & Devol |
Marked the start of commercial robot use in manufacturing. |
| 1966 |
Shakey |
SRI International |
First mobile robot able to reason about its actions; combined computer vision and planning. |
| 1973 |
Stanford Arm (first computer‑controlled robotic arm) |
Victor Scheinman |
Introduced six degrees of freedom, becoming a template for later manipulators. |
2.3 Technological Breakthroughs
| Area |
Advancement |
Impact |
| Control Systems |
Development of PID controllers and early microprocessors (1970s) |
Enabled precise, repeatable motion. |
| Sensors |
Introduction of force/torque sensors, vision systems, and proximity detectors |
Gave robots perception capabilities. |
| Programming |
From punch‑card/tape to high‑level languages (e.g., VAL, RAPID, KRL) |
Simplified robot integration and re‑programming. |
