🤖 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
How Robots Work: The Sense-Think-Act Cycle
Just like humans, robots follow a continuous loop to interact with the world. This is called the Sense-Think-Act cycle.
1. SENSE
(Input)
The robot gathers data from its surroundings using sensors (cameras, microphones, etc.).
2. THINK
(Process)
The controller (brain) processes the data and decides what to do next based on its programming.
3. ACT
(Output)
The robot executes the action using actuators (motors, robotic arms, wheels).
