4.0 CONCLUSIONS, LIMITATIONS AND RECOMMENDATIONS

4.1 Conclusion
This report presents the design and development of the MR1 and the MR2 for the

ROBOCON Malaysia 2019 competition. The robots are drafted using computer aided

design software and IronCad, and the fabrication for some components utilises advance
technology and 3D-printing to save cost and time. The components for the MR1 and the

MR2 are made up of PLA (Polylactic Acid). During the 3D printing process, we faced a

problem in printing an overhanging part which strongly affects the joining part of the robot
that causes a severe defect. Actuators are used to perform the MR2 movement using

pneumatic system. The servo motor used in the MR2 as a balancing system is controlled via
an Arduino Mega 2560 through coding. The movement range of the balancing system for

the MR2 is within 360 degrees. The MR1 and the MR2 parts are joined together by fastener
i.e. screws and nuts. For the MR2 movement, the system mainly consisted of three

components which are micro-controller, motor and pneumatic system. Arduino micro-

controller is cheaper and easier to be programmed with C language compared to the other
micro-controllers. Experiment is set to test the performance of the MR1 and the MR2 by

varying the distance and speed. The throwing mechanism and balancing system is validated
from the results obtained during testing stages.

4.2 Recommendations

Due to time constraints, the robots can only perform a few parameters of testing. For

future undertakings, it is highly recommended that the testing parameters be diversified. By

diversifying these parameters, the accuracy of the robot in performing tasks will be
enhanced and the overall outcome of the robot will be improved. The test parameters to be

improved are:

1. Testing of the movement of the MR1 when crossing the Forest and going through the

Bridge.

2. Testing of throwing mechanism of the MR1.

3. Leg mechanism for the MR2.

4. Sequence movement for the MR2.
