2.2.2 Messenger Robot 2

Figure 4 shows the architecture of electronic design for the MR1. The main

controller for the MR2 is the same as the MR2 using Arduino UNO controller. The input
for the MR1 operate based on the input signal from infrared sensor that is attached to the

Gerege gripper. The controller board will process the input signal and give the output signal
to activate the DC motor to drive the four legs.

2.3.1 Flow-chart of Programming

Figures 7 and 8 show the programming flow-chart for the MR1 and the MR2

respectively. The MR1 controlled manually and has 10 inputs to operate the MR1. While,
the MR2 only have one input signal to operate autonomously.
