Putting all the correct matches together gives us the final arrangement:

Assertion and Reason based question

Question 1

Assertion (A): Kismet is a robot which is derived from an Arabic word meaning fate or luck.

Reason (R): It is a humanoid robot designed to interact with humans through emotional expressions.

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.

Let’s examine both statements here. First, is Assertion (A) correct? Yes, it is. The name for the robot, Kismet, was specifically chosen from an Arabic word which means fate or luck. So, that part is true.

Now, let’s consider Reason (R). This statement describes what Kismet actually is. It is a humanoid robot, built back in 1997, and its entire purpose was very unique for its time. It was designed to interact with humans through emotional expressions. Think about that – it used its robotic face to convey feelings like happiness, sadness and surprise. So, Reason (R) is also a true statement.

The final piece of the puzzle is connecting them. The robot’s name (fate or luck) is directly linked to its function (interacting with humans emotionally). The name reflects the purpose. Therefore, we can conclude that both A and R are true and R is the correct explanation of A.

Application based question

Question 1

There are some cobots which are used for specific tasks in our daily life. Read these statements carefully and name the cobots used for these purposes. The statements given below:

(a) This cobot is a collaborative robot designed to assist in agricultural tasks, particularly in delicate crop handling.

(b) It is a cleaning cobot, designed to autonomously handle cleaning tasks in various environments, like offices and hospitals.

(c) It is a retail cobot, used in retail stores for tasks like stocking shelves, inventory management and assisting customers.

It’s amazing how specialized cobots have become, each with a name and a purpose. Let’s match these descriptions to the correct ones.

(a) The cobot you’re looking for that assists in agriculture, especially with delicate crops, is named Singrow.

(b) When it comes to autonomous cleaning in busy places like hospitals or offices, the correct name for that cobot is Whiz.

(c) And for the retail environment, helping with everything from stocking shelves to managing inventory, the cobot is called Nova.

Write short notes

Question 1

Write short notes on Machine.

When you hear the word ‘machine’, what comes to mind? At its most basic level, a machine is a device designed to perform a specific task or function. It achieves this by using energy to apply mechanical power. The whole point of creating machines is to make our lives easier; they can simplify tasks, increase efficiency, and reduce the amount of human effort needed. You’ll find them everywhere, in all shapes and sizes. They can range from very simple tools like levers and pulleys to incredibly complex systems such as engines and computers.

Question 2

Write short notes on Robot.

When we talk about Robots, think of them simply as programmable machines that are designed to execute specific tasks requiring little or no human intervention. Imagine giving a machine a set of instructions it can follow perfectly on its own.

So, how do they manage this? They typically have sensors, actuators and a control system that enables them to interact with their environment. The sensors act like eyes and ears, gathering information. The actuators are the moving parts, like arms or wheels, that perform the action. The control system is the brain that processes the information and gives the commands.

Because of this capability, they are assumed to be vital devices which can be used to replace human and human activities in near future.

Question 3

Write short notes on Industrial Robot.

When you picture a modern factory, you’re likely picturing an industrial robot at work. An industrial robot is a machine built specifically for use in manufacturing industries, designed to handle jobs that are monotonous and repetitive, or even hazardous tasks. They perform these duties with remarkable precision and consistency. The pioneer in this field was Unimate, which was the first industrial robot. It was invented by George Devol in 1954 and was famously put to work on the General Motors assembly line. This single event was a game-changer that revolutionised industrial manufacturing by dramatically improving safety for human workers and boosting overall efficiency.

Question 4

Write short notes on Cobot.

Let’s break down the name itself. A cobot actually stands for collaborative robot, and you might also hear it called a companion robot. The name gives you the biggest clue about its purpose! It is designed to work alongside humans in shared spaces, with the goal of enhancing both productivity and safety.

Now, how is this different from the big industrial robots you might have seen in videos? The key difference is that cobots are built with special sensors and safety features. This allows them to safely assist with tasks like assembly, packaging, and quality control right next to a person, without the need for extensive safety barriers.

Question 5

Write short notes on Agricultural Cobot.

Think about how farming often involves very careful, repetitive tasks. This is where an agricultural cobot comes in. It’s a collaborative robot specifically designed to assist in agricultural tasks, proving especially useful in delicate crop handling. For a real-world example, look at the Singrow cobot. It cleverly combines advanced sensors and AI to carry out its job with efficient and precise work, making it a powerful tool. Crucially, it’s built for safe interaction with humans, allowing people and machines to work together in the fields. The impact of this technology is significant: its application optimises labour, enhances productivity, and supports sustainable farming practices, all while reducing manual strain for farmers.

Question 6

Write short notes on Retail Cobot.

Imagine you’re in a busy shop. A retail cobot is a type of collaborative robot designed to work right alongside human staff in retail stores. Their main purpose is to help with important but repetitive jobs, such as stocking shelves, managing the store’s products through inventory management, and even assisting customers with their queries.

A perfect real-world example is a cobot named Nova. Because it is equipped with sensors and AI, Nova is quite advanced. It can intelligently navigate passages without bumping into people or displays, scan products to keep track of stock, and provide information to shoppers. The end result of having a helper like this is that it helps to improve store efficiency and enhance customer experience.

Answer the following questions

Question 1

What are the features of a machine?

When we talk about what makes something a machine, we can break it down into a few key characteristics:

1. At its very heart, a machine is an energy converter. They are built to take one form of energy and transform it into another. A common example is turning electrical energy into mechanical movement—think of a simple fan starting to spin.
2. The most obvious reason we use machines is to make work easier and faster. They significantly reduce the manual effort and time needed to get a job done, which in any industry results in much higher productivity.
3. Have you ever wondered how a simple jack can lift a heavy car? That’s a machine giving you what we call mechanical advantage. This allows us to apply a small amount of force to achieve a much greater work output. This is possible thanks to physics principles like torque, leverage, and hydraulics.
4. Another critical feature is accuracy. Machines can be engineered to perform tasks with a level of precision that humans often can’t match consistently. These precise operations are absolutely essential in high-stakes fields like manufacturing and medicine.
5. As we get into more modern technology, we see that advanced machines can operate autonomously (all by themselves) or semi-autonomously (with some human guidance). This amazing capability is driven by either programmed instructions or, even more impressively, by AI-based systems.

Question 2

Who coined the term ‘Robot’? What does it mean?

The word ‘robot’ didn’t come from a science lab, but from the stage! It was coined by the Czech writer Karel Capek for his 1920 play, R.U.R. (Rossum’s Universal Robots).

The meaning behind the word is also quite direct. The word robot is derived from the Czech word “robota”, which means forced labour. This perfectly captured the idea of the artificial workers in his story.

Question 3

How is ‘Pick and Place’ robot useful in present days?

Think about what the name itself tells you! The ‘Pick and Place’ robot is so useful in present days because it is designed to do exactly what it says: pick up an object, swivel, and place it elsewhere with incredible precision.

What makes them so valuable in modern factories? For one, these robots are much faster at this kind of repetitive work. They are ideal for tasks like rapidly inserting small components, something you’d see in the manufacturing of computer chips and watches, where parts are minuscule and must be placed perfectly.

Hence, you’ll find they are widely used in modern manufacturing industries where both speed and accuracy are absolutely required.

Question 4

‘Kismet’ is a humanoid robot. In what ways, it is significant to us?

What makes the robot ‘Kismet’ so very important is that it was designed from the ground up to interact with humans using something we all understand: emotional expressions. It was given a robotic face that is capable of conveying a range of emotions, for instance, showing happiness, sadness and surprise.

But it’s a two-way street! Kismet also had to understand our feelings. It did this by using vision and auditory sensors to interpret human facial expressions and voice tones. So, its primary purpose wasn’t to build or carry things, but to study human-robot interaction and emotional communication. This research was a breakthrough because it helped advance the understanding of how robots can engage with humans on an emotional and social level, moving beyond simple commands.

Question 5

What are the characteristics of a robot?

When we talk about what makes a robot a robot, we’re looking at a specific set of qualities. Let’s walk through them one by one.

1. Autonomy: Think about this – a robot doesn’t need a person guiding its every move. It can function independently and perform its tasks without constant human guidance. This is a core feature.
2. Sensing: Just as we use our senses, robots use theirs. They possess sensors to perceive their surroundings. This allows them to collect data about the world around them and respond accordingly.
3. Manipulation: Many robots are designed to interact with the physical world. They are capable of handling objects, which could mean anything from picking them up and moving them to executing very intricate tasks with their grippers or arms.
4. Mobility: Not all robots are stationary! Many can navigate their environment. To do this, they might use wheels, legs, or other locomotion mechanisms to get from one place to another.
5. Programmability: A robot’s real power lies in its flexibility. They can be programmed to execute a wide variety of tasks and behaviours. This programmability is what grants them such versatility in functionality.
6. Precision: When a job needs to be done perfectly, robots excel. They are often engineered to carry out tasks with incredible exactness and accuracy, far beyond what’s typically possible for a human.
7. Consistency: Imagine doing the same simple task a thousand times. A human would get bored and make mistakes, but a robot won’t. They can repeat tasks reliably and consistently, which makes them ideal for repetitive operations.
8. Adaptability: The world is always changing, and some of the more advanced robots can keep up. They can adjust to changes in their environment or tasks. This might be through predefined responses we give them or even through sophisticated learning algorithms.
9. Safety: With powerful machines, we must be careful. For this reason, safety measures are a crucial part of robot design. They are typically integrated into robots to ensure safe operation, which minimises risks to themselves and, most importantly, to others.
10. Integration: Robots often work as part of a larger team. They can be integrated with other systems and technologies. This enables them to collaborate with humans or even other robots to accomplish complex objectives together.

Question 6

Why are Cobots considered more suitable for collaborative tasks?

Think about the massive robots you might see in a car factory, often kept behind large fences. Cobots are designed with a completely different philosophy. Their very purpose is to work alongside humans in shared spaces, acting as a helpful partner rather than just a tool. This close collaboration is meant to enhance both productivity and safety.

The key to this partnership lies in their design. Cobots are equipped with sophisticated sensors and safety features that allow for safe human-robot interaction. For instance, a cobot can sense when a person is too close and will automatically slow down or stop to prevent any accidents. This is precisely why they don’t require the extensive safety barriers that traditional industrial robots need.

Beyond their safety, Cobots are also easy to program, flexible and adaptable. This makes them incredibly useful because they aren’t limited to a single, repetitive task for their entire operational life. They can be retasked and redeployed with relative ease, making them ideal for dynamic work environments where projects and needs frequently change.

Question 7

What are the characteristics of a cobot?

When we talk about cobots, or ‘collaborative robots’, we’re looking at a few special features that allow them to work right alongside people. Let’s break down their main characteristics:

1. Safety: This is perhaps the most important point. Unlike traditional robots that are often caged off, cobots are designed for safe human-robot interaction. They are equipped with advanced sensors and collision detection systems specifically to prevent injury to their human colleagues.

2. Ease of Use: You don’t need to be a highly skilled programmer to operate a cobot. They come with simple interfaces that are quite intuitive. As a result, they enable users to program the tasks required without needing any specialised knowledge.

3. Flexibility and Adaptability: Think of a cobot as a versatile team member. They are designed to be lightweight and are remarkably adaptable. Thus, cobots can be moved around and repurposed to perform various tasks, allowing them to easily shift between roles in dynamic environments where needs change frequently.

4. Productivity: By handing over certain jobs to a cobot, the whole team becomes more effective. They are capable of automating repetitive tasks, which naturally helps to improve efficiency. This also frees up human workers from tedious jobs, allowing them to focus on more complex and creative tasks.

5. Cost-Effective: Bringing this kind of technology into a workplace is more achievable than you might think. These robots are lower in cost than traditional industrial robots. This is a huge advantage, making them accessible to small and medium-sized businesses, not just giant corporations.

Question 8

How will you identify whether a given device is a robot or a machine?

It can be tricky to tell a complex machine from a simple robot! To figure out whether a device is a machine or a robot, we can look at a few key differences. Let’s break them down:

1. Autonomy: Ask yourself, how much help does it need? If the device can perform tasks on its own with minimal or no human intervention, you’re likely looking at a robot. On the other hand, machines typically require direct human intervention to get the job done.

2. Decision-Making: Think about whether the device can ‘think’ for itself. Robots are often enabled with sensors and processing capabilities. This combination allows them to make decisions, adapt to changes they encounter, and perform multiple tasks. Machines, in contrast, usually perform fixed, repetitive actions over and over without any real decision-making.

3. Interaction with Environment: How aware is the device of its surroundings? Robots are designed to interact dynamically with the environment. They use sensors to gather information and adjust their actions accordingly. Most machines typically do not sense or respond to environmental changes in real time; they just follow their pre-set instructions.

4. Complexity of Task: What kind of job can it do? Robots are capable of handling complex or flexible tasks, such as navigating spaces, manipulating objects in clever ways, or even interacting with people. Machines are usually built for simpler, single-purpose functions. Think of tasks like drilling, grinding, or moving objects in a fixed manner—that’s the classic job of a machine.

Question 9

Mention any three applications of a cobot to our daily life.

It’s fascinating to see how cobots, or collaborative robots, are becoming a part of our world, working right alongside people. Let’s look at three common applications you might encounter.

1. Agriculture: Out in the fields, cobots are a huge help. They are used for many agricultural tasks, especially those requiring a gentle touch like delicate crop handling. This teamwork helps to optimise labour and enhance productivity, making farming more efficient.
2. Cleaning: You’ve likely seen these in action. Cleaning cobots are specifically designed to autonomously handle cleaning tasks. This is incredibly useful in large environments such as offices, hospitals where cleanliness is critical, and big industrial spaces.
3. Retail: The next time you’re in a large store, look around. Retail cobots are often busy stocking shelves, carrying out inventory management to make sure products are available, and sometimes even assisting customers to find what they’re looking for.

Question 10(a)

Distinguish between Machine and Robot.

It’s easy to get ‘machine’ and ‘robot’ mixed up, but they are quite different. Let’s break down the key distinctions in a simple table. Think about what each one needs from a human to get its job done.

Question 10(b)

Distinguish between Robot and Cobot.

It’s helpful to see the key differences between a Robot and a Cobot laid out side-by-side. The core distinction really comes down to whether they work alone or with people.
