Abstract
For urban search and rescue duties (USAR) and catastrophes pacification, it is usually to put cameras and sensors into disastrous or inaccessible area to achieve better conditions for the rescue personnel. Robots are predestined to similar assignments, but requisites for such mobile systems are demanding. Stair climbing is also an important feature so that robots can get the access to higher places such as higher floors inside buildings . To overcome such a problem, with those requirements in mind, we developed the stair climbing robot Yazur. The robot Yazur has eight wheels to successfully do the task of climbing stairs. Four of the wheels are to support its weight and movement on a flat terrain. While two wheels are existing in front of the body at the top, so that they help the robot to climb the stairs in an angle 30-50 (The start to convert x-axis movement into y-axis movement). Finally, the last two wheels are locating at the top back of its bone, their task is to repose the whole robot when it is moving up to the next stair. The computer which controls the directions and motions of the robot needs no complicated calculations like other robots. Which interfaces the Bluetooth module and the H-Bridge (Motors) with appropriate decisions. When Bluetooth module receives a command from a paired device, whether a smart mobile or a PC, the controller will get that command, decide and send right directions along with speed to motors through H-Bridge
