Design and simulation of a mobile robot platform for navigation and obstacle detection
Keywords:Wireless communication, drip irrigation, Microcontroller, soil moisture sensors, nRF24L01 transceivers.
AbstractMobile platforms are expected to gain access to risk zones, harzoudous environment. A typical example is the infectious disease environment to deliver items to a sick patient. The robot is aimed to manoeuver round flat grounds in indoor environment. Computer aided design (CAD) models of the selected concepts were developed in Fusion360 and imported into SolidWorks to optimize and improve the design. The design focused on the development of the wheelbase. Arduino Microcontroller was the control board for the system and codes were developed using the Arduino software. The motor driver was used to drive the DC motor for robot navigation with ultrasonic sensor for obstacle detection at a range of 20 cm. Result shows that the robot was able to navigate round flat ground while detecting obstacles within 20 cm.
