In today's life, technology concerned with robots plays an important role in many fields because they are used to operate in hazardous and urban environments, for security, in traffic system, rescue mission as well as military operations. Some of the e robots are designed to operate only on natural terrains, but it can also use for rough terrains and artificial environments including stairways. This article represents the mechanism of how will robot climb the stairs carrying load. Its mechanical design is suitable with front wheel and back wheel driven by DC motor for climbing stairs. Although many robots had been introduced earlier have some problems like need of special device or software to control the robot etc. This design allows an advance method for robotics control using the mechanical links. Until recent years, the stair climbing robots are designed with vast hardware and robots are equipped with chain roller to climb stairs or to move on a flat surface. The mechanical design of the robot contains the fixed and flexible links of wheel legs instead of chain roller moves relative to each other to generate high friction with stairs. There is a lot of scope for improvement and this mechanism can be further modified and used in various other applications such as carrying heavy loads and thus further reducing human effort. Another scenario where this mechanism can be employed is during disaster management. A camera can be fitted on the robot to have a wide field of view of the affected areas which can further help in search and rescue operations. This robot can further be integrated with mobile devices to process the images fed by the camera and act accordingly to the stairs.
