2.0 DETAILED DESIGN

The development and design of this robot is mainly divided into three main
components which are the mechanical design, electronic design and software design. The

mechanical design caters mainly the chassis of the robot, its structure and the movement
mechanism. The electronic design is mainly for power distribution, the controller, and the

input components such as sensors, buttons and the output components such as the motor and

solenoid valves. Lastly, the software design is mainly for the programming of the controller
and the designing of software or for Computer Aided Design (CAD) software.

2.1 Mechanical Design

The mechanical design of the robot is very important as it is the main structure of a

robot and holds all of the main components. It also defines the mechanism for movement
utilizing basic machine mechanism. The robots were first designed using CAD software

before it is fabricated. This is to save time and speed up the development process. Designing
using CAD means the movement of the robot can first be simulated to ensure its

functionality. Despite that, during the fabrication, a lot of designed flaws are detected and
these flaws must be rectified or the design must be changed.

Figure 3: The design of the manual robot

Figure 3 shows the design of the manual robot. It is mainly built on a single
aluminium plate, reinforced with aluminium square tube to improve its structural integrity.
