ROBOCON Malaysia 2019 match is to deliver information fast by using a relay messenger

system, the Urtuu system [2]. The system was first invented by the nomadic Mongolians. It
was an important invention that opened a new door to exchange and to share knowledge.

Based on this concept, ROBOCON Malaysia 2019 will promote the idea of Sharing of
Knowledge or in Malay, Perkongsian Ilmu. The slogan for ROBOCON Malaysia 2019,

“Satu Langkah, Seribu Lonjakan” is analogously derived from the horse stride in the Urtuu

system which travels far and beyond in relaying the messages.

There are several tasks in the competition to be completed. The MR1 carries the

Gerege from Khangai Urtuu, which is its starting point. It goes along the Forest, Bridge,
and crosses Line 1 before reaching Gobi Urtuu. Gobi Urtuu is the starting point of the MR2.

After the MR2 reaches the Gobi Urtuu, the MR1 passes the Gerege to the MR2. Once the
MR2 successfully receives the Gerege, it can go along the Gobi Area. The MR2 passes

through the Sand Dune and Tussock to reach Mountain Urtuu. After the MR2 reaches the
Mountain Urtuu, the MR1 may enter the Throwing Zone to throw the Shagai to earn 50

points or more. Once the MR1 earns at least 50 points, the MR2 is allowed to climb the

Mountain to reach Uukhai Zone. Once the MR2 reaches the Uukhai Zone, it raises the
Gerege and the match is complete. This is called Uukhai. The first team to achieve “Uukhai”

is the winner. Therefore, there is a need to develope a Messenger Robot 1 (MR1) and
Messenger Robot 2 (MR2) that can do the tasks and earn the points.

The MR1 was developed using omni wheel method movement while pneumatic
approaches are used for the lifting, expanding, gripping and throwing mechanism.

Playstation joystick control was used as the input to the controller of the MR1. For the MR2
legged mechanism, rotating legs using DC motor was used to manoeuvre to the selected

area. Infrared sensor is used as the input for the MR2 to start the movement of the robot.

As a conclusion, the MR1 and the MR2 were developed to accomplish the task of

ROBOCON. However, there is an improvement that have to be done for the MR2, epecially

on the legged mechanism to make it easy and smooth to rotate and move.
