Abstract

A teleoperated rough-terrain robot was constructed and evaluated. The system consists of a nitro powered engine vehicle, two servo motors, RF control module, two UP-IRC SlimBoards, a servo-driver controller, three ultra-sonic ranger sensors, t wireless camera and two different kinds of batteries. Using C programming language, an in-board microcontroller-based control system was mounted on to the vehicle to allow decision making upon controlling the servos. The robot is designed to be controlled remotely through an RF transmitter. The RF communication is successful up to 450 meters. The signals from an RF receiver are fed to a microcontroller to be read and measured. Three ultra-sonic ranger sensors, with a reliability of 25 cm and range of 350 cm were attached to the system. The sensors were used to detect and avoid obstacles from the front, left and right side of the vehicle. A video feed from the camera is available to the user to view the frontal perspective of the system and status of LED indicators of the sensors and batteries. When an LED lights up there is a delay of 0.30 second before it is visible to the video feed. On the other hand the servo response from the transmitter has a delay of 0.70 second while it has a 0.50 second delay when an obstruction is detected 100 cm away from the vehicle.
