What are the different components that enable a robot to perform tasks?

The different components that enable a robot to perform tasks are:

• Sensors: Robots use sensors to learn about their environment. With this knowledge, they can move around their surroundings, avoid obstacles, and interact with objects. Commonly used sensors include cameras, lasers, and ultrasonic sensor.
• Actuators: Robots move and do things with the help of actuators. Commonly used actuators are motors, gears, and connections.
• Controller: Robot’s brain is the controller attached to it. It gives instructions to robot to perform a specific task, which is based on sensor input and a pre-written set of instructions.
