2.1 Mechanical Design

The specific functions and mechanisms required for both robots are the two

important points in the mechanical design. For the MR1, it requires a lot of manoeuvring
and has to function as a collector with the throwing capability. Therefore, the MR1 has to

be designed to be strong and firm enough to withstand the throwing force while at the same
time can move at high speed to ensure that the Gerege is passed within one minute.

As for the MR2 robot, it also requires to manoeuvre along the path, as shown in
Figure 1, on leg mechanism. Therefore, the design for the MR2 focuses the development of

the four legs such that it can function and move simultaneously, that is able to move forward
and manoeuver through its required paths. The following sub-section will further explain

the design of both robots.

2.1.1 Messenger Robot 1 Mechanical Design

The team had conducted a meeting and decided to design a manual control robot for
this unit. First of all, a rectangular shape was selected as the base for this unit out of three

initial proposed shapes such as round and triangle. The selection was based on the wheels

positioning which consist of four Tran’s wheels. After a study was conducted, there was a
total of seven directions that the robot had to travel as illustrated in Table 1.
