ROBOT PENJELAJAH BERODA AUTONOMOUS

Abstract

The wheeled robot design consists of various modules with their own functionalities. We chose
the components based on theirs specification, autonomous functionality, and in theirs prices. We assembled
these components as modules. The modules in this design are power supply module, processing module
which is used ATMega 328 microcontroller, distance sensor module, line sensor module, wireless
communication module, motor driver module and actuator module which is used DC motor. System
performance indicated with: Able to follow square, triangle, synes conture and stopping ability. Experiment
shawed that all of the modules worked as design. The robot could navigate according to contours
autonomously. We tested by using a display module. We gave inputs and then feeded to processing module
through bluetooth. From the experiment, it can be concluded that the robot which was using wall following
method could be controlled well. The PID controller performed well so the navigation could be stable. The
stable condition was achieved under 3 seconds. But the performance criteria had not been achieved because
the maximum overshoot was 41.2% which was far from the limit of 10%.
