🤖 What is a Robot?
A robot is a programmable machine designed to automatically carry out complex tasks. Unlike simple machines, robots can sense their environment, make decisions, and adapt their behavior.
Key Characteristics:
- • Programmable and configurable
- • Can sense and respond to environment
- • Capable of physical movement or manipulation
- • Operates with varying degrees of autonomy
📊 Robot vs. Other Machines
✅ Robot
Programmable, autonomous, adaptive
⚡ Automation
Fixed tasks, limited flexibility
🔧 Simple Machine
Manual operation, no intelligence
📚 History & Evolution
The concept of artificial beings dates back to ancient mythology, but modern robotics began in the 20th century with industrial automation needs.
💭 Fun Fact
The word "robot" comes from the Czech word "robota," meaning forced labor or work.
