2.2.2 Electronic Design

Figure 6 shows the system block diagram of the electronic controller hardware for

the MR2. It is the same board as the controller hardware for the MR1 but it is only used to
drive two DC motors.

2.2.3 Software Design

Arduino software is used in the design due to its simplicity and accessible user
experience. Open-source Arduino Software (IDE) is used to provide an interface to write

code and upload it to the board. Board selection in the MR2 is Arduino Uno, a micro-
controller board based on ATmega328P.

3.0 RESULT AND DISCUSSION

The MR1 and the MR2 are operated in the simulated game field as per defined by

ROBOCON Malaysia 2019. The robots are bench-marked according to the movement

speed, scored points and repeatability. The movement speed is the velocity of the messenger
robots measured in m/s in the game field while the total travelling time is the time in second

taken by the robots to navigate the game field and complete the tasks. The scored points are
the average points scored in the 10 trials and the repeatability is the successful rate for the

completion of the game. The score points of the MR1 are subjected to the picking and
