ABSTRACT

ROBOCON Malaysia 2019 requires students to build two robots to complete tasks given.
Messenger Robot 1 (MR1), is a manual robot controlled by an operator using wireless PS2.

The MR1 is designed in such a way that it moves in holonomic motion which is commonly

implemented in traditional ROBOCON competition. The MR1 picks up a Shagai using
pneumatic-powered gripper and the gripper will then be flipped to the platform for shooting

purposes. The pneumatic cylinder is mounted at the top of the slider. The shooting
mechanism idea came from conceptualizing a catapult where an elastic band such as rubber

is used to shoot the Shagai once it is released. A power window motor is used to release or
tighten the rope that is attached to the rubber. A servo-controlled gripper is also used to pass

the Shagai to the Messenger Robot 2 (MR2). The MR2 is a fully automatic robot. It has to

have four legs or otherwise, four contact points to the ground. The robot is designed in such
a way that the joints are mounted to the power window motor as actuation. The legs will

then have continuous motion as the joints are rotating.
