2.2 Electronic Component of the MR1

The pressure from the bottles is used to move the pneumatic cylinder through

pneumatic valve that acts as controller for the pneumatic cylinder. The L-shape is used to
keep the air inside the bottle tight. Encoder will calculate the distance for it to reach the

desired distance that we inputed in the programme. The requirement for the competition is

the use of emergency in ordet to avoid damaging other robots and the field. Lipo battery
acts as power supply to Arduino Due, driver and pneumatic valve. The Arduino Due and

pneumatic valve use 12 V battery while the driver uses a 24 V battery. Power windows are
used to lift the lifter up and down.

In order to throw the Shagai at the Throwing Zone, the thrower uses a pneumatic
valve that is connected with arduino as the micro-controller and pneumatic cylinder.

Microcontroller Arduino Due is implemented manually because it is the perfect board for

powerful large scale Arduino projects. It is equipped with 54 digital input/output pins, 12
analog inputs. Besides that, the robot uses four MD13S type of drivers to control the

direction and pulse width modulation (PWM).

Relay switch is used to control the switch automatically by using a signal. The
number of the drivers used in the robot are four because the robot uses four DC motors and

the drivers are connected in parallel to ensure the supplied voltage is 12 V each, thus
reducing the probability for disruption. The MR1 uses DC motor because the movement

will become faster when we supply the 24 V battery.
