20. Project development

I will describe the progress of my final project by answering the below questions.

what tasks have been completed, and what tasks remain?

For now, except for creating an electrical board to control motors, I completed almost things. My robot can move by using the motor shield (Adafruit motor shield) connected to both Arduino and Satshakit.

• Building the whole body of the robot
• Coding (Arduino IDE)

Motion test

Checking motors’ movement using Satshakit

From the above results, the remain work will be creating PCB Inter face board to connect Satshakit and DC motors.

what has worked? what hasn’t?

All planed functions work. However, I have been struggling with creating a PCB board to control DC motors. When power supply for the motors was 7.2V (rated voltage of the motor), not all motors moved. I guessed this was due to the shortage of current given to each motor.

what questions need to be resolved?

Supplying power to 4 DC motors.

what will happen when?

Today is 5th Jun. Then, my plan is shown below. - Completing all wokrs by 12th Jun
- Presentation 14th Jun

what have you learned?

Commercial arduino shields are great things. When I design electrical board, I again realized calculating power consumption is also necessary.
