The Measurement Of Tri- star Wheel

To complete the project, designers look at various aspects in order to make the Stairs Climbing Robot in indoor environment to facilitate any work to climbing the stairs. Here, we construct this robot to solve the problem. But this robot we make is a replica to the true robot. So, to carrying any heavy thing, the robot must use more big motor or hydraulix system. Most important is a the tri-star wheel. The measurement of tri star wheel must correct and right. If not, the robot can fall from stair or fail to climbing the stair.                                 

Objective And Scope

 OBJECTIVE

The main objectives of this project are:

•     To develop Stair Climbing Robot using the tri- star wheel
•     To use the Arduino Uno as microcontroller
•     To using adjustable infrared sensor to detect the object

 PROJECT SCOPE

The scope in this project is:

•  This project use in indoor application
•  This project just climbing stair onl
•    This project only can climbing the stairs with tri- star wheel based on the measurement               of wheel and size.

Introduction

                Stair Climbing Robot is a small robot for indoor environments. On even floor it drives like many other small robots with a differential drive. By this mechanism it can together with its special tri- star wheel and a support reliably climb up and down regular sized stairs. It was one of the objectives for the design to use as few actuators and sensors as possible. Stair Climbing Robot is a robot capable of climbing full size stair and driving at a reasonable space. This robot should also be able to carry the load of an average adult to act as a way to ascend stairs for those reliant on wheel chairs.   The main part of this robot is a special tri- star wheel. The tri- star wheel stair climbers use the differential to drive both the wheels and the tri- star wheel with a single motor. The motor drives the differential case and each system is driven from one of the two outputs. With the stair climbing system, the power from the motor isn't forced to be distributed evenly like in a car, rather, it is free to travel along whichever path offers the least resistance.
