2.4 Dimensions of the MR1 and the MR2

There are three pneumatic cyclinders used in the mechanical design of the MR1.
Compressed air pressure used is 6 kPa. The dimension is 98.5 cm x 75.2 cm x 68 cm (Height

x Length x Width). The weight of the MR1 is 10 kg

Figure 11: (a) The MR1 and (b) The MR2

The drawing of the MR2 is done using Autodesk Fusion 360. Based on the design,

we can see that the structure and the locomotion of the robot allows smooth movement. The
dimension of the MR2 is 74.2 cm x 64 cm x 54 cm (Height x Length x Width). The weight

of the MR2 is 8 kg.

4.0 CONCLUSION, LIMITATIONS AND RECOMMENDATIONS

4.1 Limitation

The MR1 mechanism to pick up the Shagai is slightly big, although the overall

weight passed the contest rule, and the physical size is quite large which causes minor

problems in mounting the system. The compressed air in the plastic bottles for the pneumatic
escapes quicker than initially thought.

Due to limited resources, the feets of the MR2 do not have a very reliable suspension
system. Thus, this sometimes causes the robot to stagger, leading to an unsteady movement.
