WEEK 4

Built a block diagram for Transmitter and Receiver

This week, I started doing block diagram for my project hand motion robotic arm. Block diagram is the first step to see the flow that will show the diagram that can give reader a good understanding about this project. Usually block diagram used in the development of hardware and software to expand awareness of some project or to explain the system flow. The low explanation used to keep the description simple, easy and clear to understand. The block diagram have divided into two part, which is transmitter and receiver. The transmitter block diagram on the hand controller and the receiver is on the robotic arm. This is because the transmitter will send data by using RF module transmitter to receiver by using RF module receiver.

Block Diagram of Transmitter (Hand Motion Controller)

           

Based on the diagram, the hand motion’s controller used 12V power supply, which is by using battery. The accelerometer is sensor that will detected the motion or movement, so it will send the data to 8051 series microcontroller. Then, the data will be transfer to RF module transmitter and give the signal to RF module receiver by using antenna.

Block Diagram of Receiver (Robotic Arm)

The diagram above show the block diagram for robotic arm that been use direct current power supply because the robotic arm need to use direct voltage to lifting object, so not practically use battery. After that, when the RF module receiver receive the signal, it will send the data to microcontroller and the driver IC will convert the data to move the robotic arm. So the robotic arm will move based on hand motion.
