Robotics & AI — Sample Question Bank

Agriculture

Reason — The figure shows a robot used in agricultural fields. Such robots are designed to perform tasks like planting seeds, harvesting crops, spraying fertilizers or pesticides, and monitoring crop health.

Assistant robots are intelligent machines designed to support humans in performing various tasks. They help in activities such as customer service, personal assistance, healthcare support, and industrial work. These robots can perform tasks like answering questions, providing assistance, and handling repetitive or time-consuming jobs, thereby improving efficiency. A few examples of assistant robots are Pepper, Roomba, CloiHomeBot, Astro.

Medicine delivery

Reason — The figure shows a drone used for delivering medicines. Drones are used to transport medical supplies such as medicines to remote or hard-to-reach areas quickly, especially during emergency situations.

Three benefits of health care robots are:

1. Higher precision in surgery: Surgical robots help doctors perform precise and minimally invasive operations, improving accuracy and reducing damage to surrounding tissues.
2. Faster and accurate diagnosis: Diagnostic robots analyse medical images and patient data quickly to detect abnormalities and support early diagnosis, improving treatment outcomes.
3. Better patient care and support: Care robots can monitor vital signs, give medicine reminders, and provide mobility assistance, reducing the workload on healthcare staff and improving patient comfort.

Planetary

Reason — The figure shows a central gear surrounded by smaller gears enclosed within an outer ring, which is the arrangement of a planetary gear system. Planetary gears are frequently used in robotic arms and engines because they can transfer power very efficiently.

(a) The autonomous bus can operate on its own without human intervention, as it uses sensors and AI to take decisions according to the situation on the road.

(b) The bus is fitted with a variety of sensors, such as radar, cameras, lidar and proximity sensors, which continuously observe the surroundings. When an object comes into the sensor's field, the sensor sends this input to the controller, which processes it and instructs the actuators to slow down, stop or change lanes to avoid the obstacle.

(c) AI can analyse traffic patterns in real time and optimise signal timings and routes, which helps in reducing traffic congestion.

Defence

Reason — The figure shows a tracked, armoured robot fitted with a mounted weapon system. Such robots are used in the defence sector for tasks like surveillance, bomb disposal, and combat operations in dangerous areas, keeping soldiers safe from harm.

Three advantages of Smart schools are:

1. They provide personalised attention to each student, helping ensure that all students get an equal opportunity to learn.
2. They deliver educational content in a variety of ways, making learning more engaging, effective, and attractive for students of all learning styles.
3. They free up teachers' time by handling tasks like grading, allowing teachers to focus on providing individual attention to students.

Warehouse

Reason — The robot shown is used for tasks such as storing, picking, sorting, and transporting goods, which are operations carried out in warehouses.

Assistant robots in healthcare improve patient care by performing routine tasks and supporting patients, which allows healthcare professionals to focus on more critical medical duties and improves overall efficiency.

Examples:

1. Medication delivery: Robots deliver medicines to patients, ensuring timely administration and reducing the workload of nursing staff.

2. Patient monitoring: Robots equipped with sensors continuously monitor patients vital signs and alert medical staff if any abnormalities are detected.
