2.0 PROJECT DESCRIPTION

2.1 Manual Robot

GMI built the robot which runs on 4 DC motors, accompanied by omni wheels to

allow flexible movement. Omni wheels allow the user to manoeuvre the robot easily and
quickly around sharp turn and obstacles in the game field. Servo motor and stepper motor

are not used in the movement of this robot because accuracy is not needed. DC motors on

the other hand is cheaper, fast, easier to code and can easily be wired to the controller. The
team uses a PlayStation 2 wired controller to manually control the robot since the

competition requires a manual robot to assist the other robot. This controller is plugged into
a Cytron PS2 Shield which is directly stacked on top of the Arduino Mega. The team chooses

a wired controller rather than the wireless controller to prevent unwanted signal interference
and the response is much faster than the wireless controller.
