3.0 TESTING AND RESULTS

Testing of a system is very important to ensure the functionality and reliability of
the robots. In this project, the test focuses on the movement of the manual robot, the holding

and dropping of the Gerege, the lifting of the Shagai and the throwing or launching of the
Shagai. For the second robot, the testing is focused mainly on the movement of the

mechanism, the movement of the robot across the Sand Dune and Tussock and lastly the

climbing at the Mountain area. The movement and mechanism were tested so that they
worked smoothly. The amount of air used for the pneumatic system is also monitored to

ensure that enough pressure is carried during the competition. The movement of the cylinder
and the functionality of the valves are also tested.

On the electronic side, first of all, it was to ensure that no short circuit occured in the
system. This is done by using a multi meter. Then, the pin assignments were thoroughly

checked and the input and output signals were tested. For example, the display and keypad

are tested to ensure they display the right information and give the right character,
respectively. Calibration of the sensors is made at this phase. The movement of the motor

was also tested so that it moves according to the speed and direction it has been programmed.

4.0 CONCLUSION, LIMITATION, RECOMMENDATIONS

This project has achieved building two robots. They were able to build according to

the specification designated by the organizer. These robots were tested and were able to

carry out the pre-described tasks. Even though the testing show promising results, the
outcome of the competition is yet to be determined as in a competition a lot of things can

happen and it also depends on the robot operator as well as the skill, efficiency and
teamwork of the participants.

This project faces issues like the limited resources and budget to produce fully
functional robots. Building robots need a lot of time, manpower and skills. As the students,

we still need to attend classes, do the assignments and use the lab. In addition, the
availability of the machine to work with is very limited. The funding provided by the from

the institute is small and we face bureaucracies. This has caused the design to change several

times to adapt to the available components that were mainly scavenged from previous
robots. This resulted in the robots to be different from previously envisioned. The team also
