ABSTRACT

For Messenger Robot 1 (MR1), the concept of a forklift was used since the Shagai is pretty

heavy. Power window motors are used as the rotary actuator and pneumatic pistons are used

as linear actuators and is controlled by a wireless controller. The power window motors are
provided with 24V supply to make the motor run faster. The mechanism for holding our

Gerege is very simple. We connect the arm to a pneumatic cylinder that is positioned
vertically during the starting of the game so that the Gerege is higher than the upper part of

the robot. When passing Gerege, the pneumatic piston will pull the arm down and pass the
Gerege to Messenger Robot 2 (MR2). The arm also acts as a clamp when carrying the

Shagai. Legged robot is a mobile which uses mechanical limbs for movement. Legged robot

can do many tasks that cannot be done by wheeled robot. In ROBOCON 2019, the MR2
which is a four-legged robot is built to pass through obstacles such as Sand Dune, Tussock

and Mountain Urtuu after receiving the Gerege from the MR1. Then, when the MR2 reaches
Uukhai Zone after climbing up Mountain Urtuu, the MR2 will lift the Gerege and this is
