Q1. Which of the following is NOT a type of robot based on its locomotion mechanism?
a) Wheeled robot
b) Bipedal robot
c) Quadrupedal robot
d) Hydrogen robot
Show Answer
Correct Answer: d) Hydrogen robot
Explanation: Hydrogen robot is not a classification based on locomotion mechanism. Wheeled robots move on wheels, bipedal robots walk on two legs, and quadrupedal robots walk on four legs. However, “hydrogen” refers to a type of fuel, not a locomotion mechanism.
Q2. What type of robot is commonly used in assembly lines for manufacturing automobiles?
a) Humanoid robot
b) SCARA robot
c) Delta robot
d) Cartesian robot
Show Answer
Correct Answer: b) SCARA robot
Explanation: SCARA (Selective Compliance Assembly Robot Arm) robots are commonly used in assembly lines for manufacturing automobiles due to their speed, precision, and ability to manipulate objects in a controlled manner.
Q3. Which of the following is NOT a component of a typical robotic arm?
a) Actuator
b) Gripper
c) Sensor
d) Battery
Show Answer
Correct Answer: d) Battery
Explanation: While batteries may power robots, they are not typically considered components of robotic arms. Robotic arms typically consist of actuators for movement, grippers for object manipulation, and sensors for feedback and control.
Q4. What is the term for a robot designed to resemble and perform tasks like a human?
a) Android

Q6. Which of the following is NOT a potential application of medical robots?
a) Surgery
b) Rehabilitation
c) Food delivery
d) Telemedicine
Show Answer
Correct Answer: c) Food delivery
Explanation: While robots are used in various medical applications such as surgery, rehabilitation, and telemedicine, food delivery is not a typical application of medical robots.
Q7. Which of the following is NOT a category of industrial robot based on its configuration?
a) Cartesian robot
b) SCARA robot
c) Snake robot
d) Delta robot
Show Answer
Correct Answer: c) Snake robot
Explanation: Snake robots are not typically categorized as industrial robots based on their configuration. Cartesian, SCARA, and Delta robots are common configurations used in industrial automation.
Q8. What type of robot is commonly used for aerial surveillance and photography?
a) Humanoid robot
b) Drone
c) Robotic arm
d) Vacuum robot
Show Answer
Correct Answer: b) Drone
Explanation: Drones, also known as unmanned aerial vehicles (UAVs), are commonly used for aerial surveillance and photography due to their maneuverability, versatility, and ability to capture images and videos from various angles.
Q9. Which of the following is a type of mobile robot designed to operate in outdoor environments?
a) Robotic vacuum cleaner
b) Lawnmower robot
c) SCARA robot
d) 3D printer
Show Answer
Correct Answer: b) Lawnmower robot
Explanation: Lawnmower robots are designed to operate in outdoor environments, autonomously navigating lawns to mow grass, making them a type of mobile robot suited for outdoor tasks.
