Designing an Autonomous Mobile Robot based on Rocker-Bogie Concept for Terrain Purposes

Abstract

Currently, extensive research has been done on improving self-controlling mobile robots. This robot is called autonomous mobile robots (AMRs) and it was designed for various applications like moving around in places such as libraries, restaurants, and healthcare. This paper focuses on designing a six-wheeled mobile robot using Fusion 360 software, based on Rocker-Bogie structure. The main idea from the Rocker-Bogie concept is that it does not use springs or separate stub axles for each wheel, allowing the robot’s body to overcome obstacles like rocks, ditches, and sand. The actuator of the DC motor for each wheel was used to study the robot’s stability and its movement. Meanwhile, the movement of the robot was controlled by implementing a user graphical interface (GUI) using Blynk software.  There are four main directions for the movement of the robot: moving forward, backward, and turning left and right position. Importantly, the Rocker-Bogie can be a starting point for developing an independent mobile robot that can navigate different terrains like sand, grass, and roads. This capability comes by using various sensors that help the robot navigate its surroundings effectively.
