Abstract - The purpose of this project is to develop a stair-
are some of the technical problems faced by traditional robots which use vacuum suckers. A new negative pressure adsorption mechanism is used in the design of the robot. This mechanism generates and maintains negative pressure and adsorption force by using the air’s rotational inertia effect; therefore, the structure incorporating this mechanism is called the electrically activated rotational-flow adsorption unit. The most important characteristic of the adsorption unit is that it can function without being in contact with the wall, which fundamentally solves these technical problems associated with traditional climbing robots. For improving the robots load ability and obstacle surmounting ability, it has been designed a square shaped rotational-flow absorption unit and soft skirt structure. These have been tested in the actual wall and results shows that the robot can move stably. Some robots have been designed for traversing through stairs and obstacles by researchers such as quadruped and hexapod robots. Although these robots can traverse stairs and obstacles, but they usually don’t have smooth manoeuvring on flat surfaces due to their motion on legs [1]. On the other side wheeled and leg-wheeled robots have been introduced that they can climb only one stair [6].
climbing robot which can able to perform process of climbing and landing by improving the combination of rocker Bogi mechanism. The combination of two different mechanism makes more efficient in carrying load, reduce friction on ground or climbing and cannot get the backward force due to gravitational force. In our project, the robot is equipped with Tri-Star wheels which enable us to carry load up and down the stairs. It also eases the movement of robot in irregular surfaces like holes, bumps, etc.
1.INTRODUCTION A stair climbing robot is a specialized robotic system designed to navigate and traverse staircases, overcoming the challenges posed by changes in elevation and varying terrains. Unlike traditional wheeled robots, which may struggle with stairs and uneven surfaces, stair climbing robots are equipped with mechanisms that allow them to ascend and descend steps efficiently. The design of stair climbing robots can vary, and different models may use wheels, tracks, or unique configurations like a star wheel design to achieve stability and mobility on stairs. The primary goal of these robots is to extend the reach of robotic systems into environments with complex geometries, making them versatile tools in industries ranging from emergency response to logistics and exploration
4 PROPOSED SYSTEM If the robots climb, decline through a sloped path, the robot switches to star-wheels motion. The star-wheels can rotate freely around their axes. One of the wheels of the star-wheel get fixed on one stair as a base and the rotation of the starwheels effects in stair climbing. It allows the robot adapts itself with respect to path curvature and prevents the shocks of changes of path slope.
2 OBJECTIVES OF WORK To develop the intelligent automated stair-climbing robot which can carry heavy load on the stair. 2. To develop the more efficiency climbing and lending performance by using the process of wireless control system 3. To create a stair climbing robot that can carry a payload up and down a standard flight of stairs, while maintaining wireless control.
3 EXISTING SYSTEM The inability to climb coarse walls, frictional resistance and abrasion of suckers, and poor obstacle- surmounting ability
