Understanding Both Fields

What Is IoT (Internet of Things)?

IoT refers to the network of physical devices connected to the internet, enabling them to communicate, collect data, and perform automated actions.
Examples: Smart homes, wearable health trackers, smart agriculture sensors, industrial machines connected for real-time monitoring.

What Is Robotics?

Robotics involves designing, building, and programming robots that can perform tasks autonomously or semi-autonomously.
Examples: Industrial robots, medical robots, autonomous drones, service robots.
