Table 2 is a list of wheelchair and robotic arms movement commands. If the W1-Fi receiver receive: F, B, L, R signal, then the wheelchair would move. For example, if the letter “L” is received then the wheelchai would move to the left while letter “R” would make it move to the right. “F” signal makes it move forward anc

Figure 1. An Arduino microcontroller Microcontroller is a device which has a similar function to a computer, but it is smaller in siz [8, 9]. In a microcontroller, there are memory and I/O tool in the chip, e.g., an Arduino microcontroller i Figure 1. Currently, there are many home appliances or office equipment using microcontroller, such 4 washing machine, microwave, handphone, PDA, home security system, etc. 2.3. Wheelchairs and robotic arms application When the wheelchair and robotic arms are turned on, gyro sensor, which is shaped so that it looks like a hat, is put on the head, and would detect the tilt of the user’s head. After the tilt is detected, the informatior would be delivered to the wheelchair and robotic arms microcontroller through Wi-Fi signals. After the information is acquired, the wheelchair or the robotic arms would move according to the tilt. The flowchart ir Figure 2 shows the process of the wheelchair and robotic arms movements, while the flowchart in Figure 3 shows the process of controller (hat). 2.2. Microcontroller

detects Robotic arms application is controlled by the user’s head equipped with gyro sensor. The sensor he tilt of the user’s head and send the positional value of aX, aY to the microcontroller attached in the wheelchair/robotic arms. Consequently, after the tilt is determined, the wheelchair/robotic arms would move according to the acquired information on the tilt. Arduino functions as a controller of wheelchair or servomotor (X) and (Y). Table 1 is the specification of the device and software used in the wheelchair/robotic arms application. The wheelchair uses a motor driver to move the motor controlled by Arduino microcontroller, while the robotic arms designed is using acrylic equipped with five servos but it used only two servos. Meanw hile, the list of wheelchair movements based on sent signals delivered through Wi-Fi could be found in Table 2.
