Robotics is a field of engineering that deals with the design, construction, operation, and application of robots. Robots are machines that are able to perform tasks automatically, often by mimicking human actions. We all know engineering students may face difficulty in practical examinations. So, here we bring some robotics viva questions:
What are the key components of a robot?
- Controller: Processes sensor data, plans actions, and controls the actuators.
- Power Supply: Provides energy to the robot.
- Manipulator/Arm: The physical part of the robot that interacts with the environment.
- Sensors: Provide information about the robot’s environment and its own state.
- Actuators: Motors or other devices that provide motion to the manipulator.
- End Effector: The tool attached to the manipulator, designed for specific tasks (e.g., grippers, welding torches).
Explain the concept of robot programming.
Robot programming involves instructing the robot to perform specific tasks. This can be done through various programming languages or graphical interfaces. Programmers define the robot’s motions, sequences of actions, and responses to sensory input.
What are the different types of robots?
Robots can be classified based on their functionality, application, and structure. Some common types include:
- Service Robots: Designed for tasks like cleaning, security, and healthcare.
- Industrial Robots: Used in manufacturing settings for tasks like welding, painting, and assembly.
- Cartesian Robots: Move along three linear axes (x, y, z).
- Mobile Robots: Capable of moving around, such as autonomous vehicles or drones.
- Articulated Robots: Have multiple joints and degrees of freedom, allowing for complex movements.
- SCARA Robots: Have two parallel rotating joints and one linear joint, commonly used for assembly tasks.
What are some common robot programming languages?
ROS (Robot Operating System): A widely used open-source software framework for robotics.
C++: A powerful programming language often used in robotics applications.
Python: A popular language for scripting and prototyping robot applications.
MATLAB: A technical computing environment with tools for robotics simulation and control.
Explain the concept of kinematics in robotics.
Kinematics deals with the motion of objects without considering the forces involved. In robotics, kinematics is used to describe the robot’s position, velocity, and acceleration based on its joint angles and movements. Inverse kinematics is the process of determining the joint angles required for the robot’s end effector to reach a specific target position and orientation in space.
What is artificial intelligence (AI) and how is it related to robotics?
A branch of computer science that focuses on creating intelligent machines that can perform tasks that typically require human intelligence, such as learning, problem-solving, and decision-making. AI plays a crucial role in enhancing robot capabilities. AI techniques are used for tasks like perception, navigation, planning, and decision-making, allowing robots to become more intelligent and autonomous.
What is the concept of reinforcement learning?
Reinforcement learning is a type of machine learning where an agent learns to perform tasks by interacting with its environment and receiving rewards or penalties for its actions. This approach is used in robotics for tasks like navigation, manipulation, and control, enabling robots to learn from experience and adapt to new situations.
These robotics viva questions are some very important for engineering students. But you need to prepare some more for deeper understanding.
