Robotics blends mechanics, electronics, and software to build machines that sense, think, and act. A typical robot includes:
- Sensing (e.g., cameras, ultrasonic, encoders)
- Computation (microcontroller or single-board computer)
- Actuation (motors, servos, pneumatics)
- Power and structure
From floor-cleaning bots to surgical assistants, robots are becoming more capable and affordable. If you’re new, start with a small kit (e.g., line follower or obstacle avoider), learn basic programming, and iterate.
Key terms
Autonomy – ability to act without human control. Manipulator – robot arm. Mobile robot – a robot that moves through an environment.
