Q2. Explain how different kind of motions are achieved in a Drone
Ans. 
Different motions in a drone are achieved through varying the speed and direction of the propellers.
• Changing the speed of the propellers controls the altitude of the drone.

• Varying the speed of propellers on different sides of the drone allows it to move forward, backward, left, or right.

• Adjusting the speed of the propellers diagonally creates rotational motion for turning.

• Combining these motions enables the drone to pe

Q4. Explain PID controller and its tunning.
Ans. 
PID controller is a control loop feedback mechanism used in systems to control process variables.
• PID stands for Proportional, Integral, Derivative.

• Proportional term responds to the current error.

• Integral term corrects the accumulated error over time.

• Derivative term predicts future error based on current rate of change.

• Tuning involves adjusting the three parameters (P, I, D) to achieve desired system response.

• Example: I...read more
