Motion means the ability to move. A robot can move around in space and change its position or direction. Define linear, angular, and circular motions in robots.

Answer

Linear Motion: Linear motion in robots refers to the movement of a robot in a straight line. The robot in linear motion travels in a straight line and its displacement is proportional to the time elapsed.

Angular Motion: Angular motion is the rotational movement of a robot or its part around a fixed axis. In this motion, the robot changes its direction by rotating through a certain angle.

Circular Motion: Circular motion is the movement of a robot or its part along a circular path. In this type of motion, the robot continuously changes its direction while moving around a fixed centre.

"Robots are flexible mechanical machines." Justify this statement.

Answer

Robots are called flexible mechanical machines because they are designed with links, joints, actuators, and controllers that allow them to perform a wide variety of tasks. Robots can change their position, direction, and movement according to the task requirements. They can be reprogrammed to perform different operations without changing their physical structure. Due to their flexibility, robots can be used in different environments and applications such as manufacturing, medical surgery, transportation, and space exploration. This ability to adapt and perform multiple tasks makes robots flexible mechanical machines.

"All robots are machines, but all machines are not robots." Prepare a write-up on the same.

Answer

All robots are machines because they are electromechanical devices designed to perform specific tasks using mechanical parts, electronic components, and computer programs. Robots are capable of sensing their environment, processing information, and performing actions either autonomously or with minimal human intervention.

However, all machines are not robots. A machine is any device that helps humans perform work more easily, such as a fan, washing machine, or calculator. These machines work only according to fixed instructions and do not have sensors, decision-making ability, or adaptability. They cannot sense the environment or make decisions based on inputs.

Robots, on the other hand, can process sensor data, make decisions, and adapt to changes in their surroundings. Therefore, while every robot is a machine, every machine cannot be called a robot, which justifies the statement.
