Robotics Components FAQs

What is the use of a microcontroller in robotics?

A microcontroller acts as the brain of the robot. It processes input from sensors and sends signals to motors or actuators to perform actions. Common microcontrollers include Arduino Uno, ESP32 Dev Board, and Raspberry Pi Pico.

What types of motors are used in robotics?
  • DC motor for simple movement
  • Servo Motor for precise angle control
  • Stepper Motor for accurate positioning
  • For beginner robots, the SG90 Micro Servo Motor and BO geared motors are widely used.
Why are motor drivers used in robotics?

Motor Drivers control the speed and direction of motors. Microcontrollers cannot directly power motors, so motor drivers act as an interface between the controller and the motor. A common motor driver used in robotics projects is L298N Motor Driver Module.

What is the primary use of the robot chassis and why does it play an important role?

A robot chassis is the structural frame that holds all components like motors, sensors, batteries, and controllers. It provides stability and allows the robot to move efficiently.

What power sources are used in robotics projects?
  • 18650 lithium batteries
  • 9V batteries
  • Rechargeable Li-ion battery packs
  • These provide power to motors and electronic components.
What is an IoT module and its role in robotics?

IoT modules allow robots to connect to the internet and communicate with other devices. They are used for remote monitoring and smart automation. Examples include Wi-Fi modules and Bluetooth modules.

Which robotics components are best for beginners?
  • Arduino Board
