Abstract

This report presents the study on a stairs climbing robot which will be manually controlled using radio frequency (RF). RF control implements the use of wireless technology to propagate data. This report includes the process flow of the project, literature review, the development of the robot, and the tests conducted on the stairs climbing robot. In integrating the controller with the robot, a radio frequency control circuit is modified to fix it with the robot structure and mechanical system. As the robot is developed, it has been tested on three different tasks including a stairs-climbing task. Generally, the structure of the stairs climbing robot is developed mainly from the aluminium L bars. Two power window motors are used as the robot’s source of movement. The motors are attached to two wheels through two shafts. The robot has four “legs” attached to each of the two wheels that are developed from aluminium L bars. This is purposely to make the stairs climbing robot ‘catch’ the stairs in order to climb the stairs. Furthermore, the RF control system is developed by modifying the normal RF control circuit from a normal RF control toy. As for the result of this project, two out of three of the objectives which are to modify a RF circuit and integrate to the robot mechanical system, and to ensure that the robot able to receive and send command signal between the robot and the controller by using the RF signal has successfully been achieved. For the stairs climbing task which implies to the first objective of this project that is to design and develop a robot that has capability to climb stairs, the robot managed to climb the stairs after 20 times of tries.
