Activity: Do a research about the stepper motor and servo motor

Objective: To know more about the stepper motor and servo motor. 

Content/ Procedure:

1. Do a research about the stepper motor and servo motor
2. Do a comparison which is better to works as peristaltic pump in order to deliver the fluid from input to output.

Result/analysis:

     1. Servo motor

• Fast, high torque, accurate rotation within a limited angle 
• Generally a high performance alternative to stepper motors, but more complicated setup with PWM tuning.
•  Suited for robotic arms/legs or rudder control etc.

      2. Stepper motor

• Slow, precise rotation, easy set up & control
• Advantage over servo motor in positional control, where servo requires feedback mechanism and support circuitry to drive positioning, a stepper motor has positional control via its nature of rotation by fractional increments.

Conclusion

Stepper motor is better than servo motor because slow, precise rotation, easy to set up and control. Besides that, a stepper motor has positional control via its nature of rotation by fractional increments.
