…………… actuators use compressed air to create motion in robotics to perform the tasks.

1. Pneumatic
2. Electric
3. Hydraulic
4. Rotatory

Fill in the blanks:

1. Gear teeth are also known as cogs which has been derived from the term ……………. .
2. ……………. teeth refer to the interlocking of gear teeth to transmit motion and power effectively.
3. ……………. gears are one of the most commonly used gears to transmit power between parallel shafts, with teeth aligned parallel to the shaft axis.
4. In robotics, electric actuators are the commonly used actuators which convert electric energy into ……………. motion.
5. The controller serves as the ……………. of a robot which helps in processing and executes programmed commands.
6. In ……………. systems, the users select fan speeds ie., low, medium, high with the help of a regulator.
7. ……………. actuators are the actuators that generate motion by using pressurised fluid.
8. In robotics, ……………. control system uses technology and machines to complete the tasks.

Assertion (A): An automatic control system operates independently with the help of a controller.

Reason (R): It means that this control system requires continuous human intervention and decision-making to perform the desired tasks.

Based on the above discussion, choose an appropriate statement from the options given below:

1. Both A and R are true and R is the correct explanation of A.
2. Both A and R are true and R is not the correct explanation of A.
3. A is true but R is false.
4. A is false but R is true.
5. Both A and R are false.

The seamless integration of sensors, actuators and controllers is essential for an effective robotic system. It maintains precision and operate autonomously, with the controller managing complex interactions between sensors and actuators in real time. Each of these components has its own role in a robotics system.

Read the following statements and identify the components used in a robotic system.

(a) It provides input by detecting environmental conditions (like temperature, distance or pressure) or internal states (such as position or speed), sending this information to the controller.

(b) It acts as the brain of the system and after processing sensor data, makes decisions based on programmed algorithms. It determines the necessary actions for the robot to perform tasks accurately.

(c) Finally, it executes the actions and converting electrical signals from the controller into mechanical movement, such as turning a wheel, moving a robotic arm or gripping an object.
