The shooting mechanism which was placed above the MR1 bot had added to the total height

of the robot which did not met the specification set by the rules. The pressure transferred
from the air-tank system also had insufficient power to throw the Shagai into the Landing

Zone.

2.1.2 Electronic Design

2.1.2.1 Robot’s Drive

The robot’s drive is designed to be used as a multi-purpose drive.

 Line following mode
 Manual drive mode

The line-following mode of the drive is used when we need the bot to travel in the
main area and in accordance with the lines made on the game field from the starting zone to

the loading zone with ease.

The line-following mechanism on the MR1 bot is used to quickly get from the

starting zone to the loading zone of the game field (passing through the poles set). This is
done using the Cytron LSA08 sensor. It has two modes to be used:

 Digital value mode

 Analog value mode

Figure 2: LSA08 Sensor

We have used the digital value mode which can instantly follow the fixed value that

we have set at the starting zone. The digital value mode can make a quick response when
there is a turn at the pole and it enables the bot to move faster. Analog value mode was not

selected because this mode will keep the bot to always follow the line which will decrease
its speed as it keeps adjusting its position.
