of the pneumatic components may wear out quickly due to friction. The cylinders can also

leak easily when it is not carefully handled. As air can easily be compressed, the moving
speeds of the pistons are relatively uneven. Finally, loud noises were also produced when

compressed air was released from the pneumatic components. The other limitation is that
the robot legs cannot move faster as the legs are at risked of getting stuck between the legs.

Moreover, the MR2 cannot hold heavy load since the selected motor is not sufficient to

operate.

4.2 Recommendations

Before switching on a compressed air supply unit at the MR1, one should thoroughly

inspect the whole circuit to see if there are any loose parts, abnormal pressure or damaged
tubes and cylinders. A loose tube will cause the robot to shake violently due to the high

pressure built up inside it. Therefore, each time before the system pressure is increased,

thorough inspection of the entire circuit is required to prevent accidents.

To make the MR2 robot hold heavier load, the legs need to be made bigger.

Furthermore, the motor needs to change from the DC geared motor (12 V 248 RPM) to the
DC geared motor (12 V 120 RPM) for better performance.

5.0 ACKNOWLEDGEMENTS

We would like to express our deepest appreciation to all who have provided us the
possibility to complete this report and to build our robots. A special gratitude goes to our

lecturers, Dr Rozan Boudville, Prof. Madya. Ir. Dr. Zakaria Bin Hussin, Dr. Saiful Zaimy

Bin Yahya and Ir. Khairul Azman Bin Ahmad whose contributions in providing stimulating
suggestions and encouragement, have helped us to coordinate our project in building the

two robots and writing this report.

Furthermore, we would also like to acknowledge with much appreciation the crucial

role played by Mr Adi Izhar Che Ani who gave us the permission to use all the required
equipments and provided the necessary materials to enable us to complete the development

of our robots. A special thanks goes to our team mates, who have helped to assemble the
parts and gave good suggestions in completing the robots. Last but not least, many thanks

go to Universiti Teknologi Mara (UiTM) Pulau Pinang Campus, Permatang Pauh for

trusting us to participate in ROBOCON Malaysia 2019.
