WEEK 6 (BUY THE COMPONENT PART 1)

In this week I find and buy the component through online, the component that I buy shown in the figure below there is an ultrasonic sensor, multi-color rainbow wire, 12V DC motor pump high pressure and Arduino. The price for all component below has been surveyed before and this is the lowest price that I can find. But there is more component that I can't find through online, so I have to go and buy the component at Jalan Pasar. Why I choose Jalan Pasar is because at Jalan Pasar there are many electronic components are sold there.

WEEK 5 (circuit diagram)

In this week the circuit diagram will be make using Protesus 8 and the circuit diagram is shown in figure 5 below.


Figure 5: Circuit diagram.

In figure 5 shown circuit diagram of the Development of Window Cleaning Robot. The first component is the ultrasonic sensor as a sensor to detect the obstacle which means the end of the frame. secondly, the sensor will send the signal to the main controller which is an Arduino. After that, the Arduino will send the signal to the motor driver. Next, the motor driver will run the motor to make a move whether right or left regarding the path that has been programmed. Lastly is Infrared sensor the function of the Infrared sensor is to make the robot stop by sensing the black line that has been placed on the surface of the window.

WEEK 4 (flowchart and path)

On this week the flowchart and the Path for the Window Cleaning Robot have been made. Figure 3 and 4 show the flowchart and path of the Window Cleaning Robot.

Figure 3: Flowchart of Window Cleaning Robot.

The flowchart begins with a start and then move forward. After that, the ultrasonic sensor will decide if there is have an obstacle which means yes the robot will turn 180-degree right if there is no obstacle the robot will stay move forward. Next, after the robot makes a turn 180-degree right the robot will move forward again until the sensor detect the next obstacle then make a turn 180-degree left. Then the robot will repeat the same move regarding to the path shown in figure 4 until the robot detects sensor the stop line using Infrared and the robot will stop immediately.

WEEK 3 (block diagram)

On this week I have been changing the block diagram from 3 ultrasonic sensors to 1 ultrasonic sensors. Moreover, I have been adding 1 Infrared sensor on the project. The function of the ultrasonic sensor is to detect the obstacle which means the end of the window frame. Then, the function of the Infrared sensor is to detect the stop line that has been placed on the surface of the window. Figure 1 and 2 show the circuit diagram before and after the change have been made. Finally, the block diagram is completely done.
