How does data acquisition play a key role in Artificial Intelligence project cycle?

Answer

Data acquisition is a key step in the AI project cycle because it involves collecting the required, relevant and sufficient data (as per the project’s data requirements) from reliable sources such as databases, APIs, web scraping, surveys/questionnaires and sensors/IoT devices. Good-quality and accurate data helps the AI model learn correct patterns and make more reliable predictions/decisions, so the success of an AI project depends greatly on proper data acquisition.

What will be the output of the following Python code?

x = [1, 2, 3, 4]
x.append([5, 6]) 
print(x)

Answer

[1, 2, 3, 4, [5, 6]]

The append() method adds the given element as a single item at the end of the list. Here, [5, 6] is a list, so it is added as a nested list, not as individual elements. Hence, the final list becomes [1, 2, 3, 4, [5, 6]].

What will be the output of the following Python code?

a = "hello" 
b = "world" 
print(a + b) 

Answer

helloworld

The + operator is used for string concatenation in Python. It joins the two strings "hello" and "world" without adding any space, so the output is helloworld.

What will be the output of the following Python code?

x = {1: 'apple', 2: 'banana'}
x[3] = "cherry"
print(x)

Answer

{1: 'apple', 2: 'banana', 3: 'cherry'}

In a Python dictionary, values are stored using keys. The statement x[3] = "cherry" means that the value "cherry" is assigned to the key 3. This adds a new key–value pair to the dictionary, which is then displayed when the dictionary is printed.

Describe the role of sensors in robotics. Give any two examples of different types of sensors.

Answer

Sensors act as the "sense organs" of a robot. They detect changes in the robot’s surroundings or inside the robot (like distance, light, sound, temperature, pressure, position, etc.) and convert this information into electrical signals. The robot’s controller uses these signals to make decisions and control actions, such as navigation, obstacle avoidance, safety, and accurate movement.

Examples:

1. Vision sensor (Camera) — Captures images/video so the robot can recognise objects and support tasks like inspection and navigation.
2. Proximity sensor (IR/Ultrasonic) — Detects presence or distance of nearby objects without contact, helping in obstacle detection and collision avoidance.

Explain how gears are used in robotics. Describe any two types of gears.

Answer

In robotics, gears are used to transmit motion and power from a motor to different parts of the robot (like wheels, arms, grippers). By changing the gear ratio, gears can increase torque (turning force) for lifting/gripping or increase speed for faster movement, and also help in smooth, controlled and precise motion of robot mechanisms.

Types of gears:

1. Spur gears — Spur gears have straight teeth and are mounted on parallel shafts. They are the most commonly used gears and are suitable for simple power transmission.

2. Helical gears — Helical gears have angled teeth, which allow smoother and quieter operation compared to spur gears. They are used in applications where high torque and reduced noise are required.

How does the decision making by humans differ from that of the machines?

Answer

Human decision-making and machine decision-making differ in the following ways:

• Basis of decision: Humans often take decisions subjectively, influenced by feelings, experiences and personal judgement. Machines take decisions logically, following programmed rules/algorithms and available data.
• Bias and emotions: Humans may show bias and may be emotional while deciding. Machines are generally objective (not affected by emotions), so their decisions are more consistent.
• Speed and adaptability: Humans can be creative and adaptive, learning from situations, but they are usually slower. Machines can process information very fast and handle many variables quickly, but they act within their algorithmic limits.
