The article presents the design and testing of the functional properties of a wheeled mobile robot used for inspection or light transport purposes. A four-wheeled design driven by DC motors without direct feedback was developed. For the developed structure, a two-level control system was designed based on an ATmega328P microcontroller, a proximity sensor, a video camera, and wireless signal transmission in the Wi-Fi standard, and then control algorithms were developed using signal analysis from the proximity sensor and image analysis based on the OpenCV library. The control system and algorithms enable both autonomous operation of the robot and manual control. Based on the prototype, tests and studies of the robot’s driving properties were conducted.DESIGN AND TESTING OF PROPERTIES OF FOUR-WHEELED MOBILE ROBOT
The paper presents the design and testing of functional properties of a mobile robot used for the purposes of inspection or light transport. Four-wheel-driven design using DC motors without direct feedback is developed. For the robot design a two-level control system is proposed, which is based on microcontroller ATMEGA328P, proximity sensor, video camera and wireless transmission of signals in the standard WI-FI. Next control algorithms using signal analysis of the proximity sensor and image analysis based on OpenCV library are introduced. Control system and algorithms allow autonomous operations or manual control of the robot. Based on the robot prototype many tests and experiments including study of robot properties are worked out.
