Abstract:
This paper explains the comparison of a mobile robot controller done by a group of final year mechatronics
undergraduates (BET in Mechatronics) at UniKL Malaysia France Institute. A mobile robot integrated with a WIFI
Webcam for home security purposes has been developed and called R2D Home Security robot. The R2D capable to
operate with 2 different modes AUTO mode and MANUAL mode where it controller is dedicated to navigate it by:
moving forward and reverse, detecting obstacle and presence of human movement, detecting high temperature
arises, and controlling a camera viewing area. The R2D have been controlled using two types of controller
separately. A Programmable Logic Controller (OMRON CPM2A) has been used in the first place, followed by a
microcontroller PIC Interface Free Controller (IFC). The comparison of the controller will focus on; interfacing of
the controller with the hardware such as sensors and motor drivers, the programming language, programming
capacity, future development works, and expandable functionality of R2D itself. With some tabulates of result and
testing both controllers applied to R2D had given numerous advantages and disadvantages depending on the
situation
