A Miniature Wheel Arrangement for Mobile Robot Platforms

Abstract

The mini wheel for mobile robot is to be used for providing precise direction control for a wheeled mobile robot. The design and operation of this device is simple and straightforward involving minimum time for its assembly with the actuator (stepper motor) and maximum ease of alignment / adjustment through a specially developed hollow jaw and screw arrangement on top of the device. This mini wheel can be operated in a tricycle configuration (Fig. 1) to steer a mobile robot for line tracking applications (by either using it in the front or back end of the mobile robot platform or base). Combinations of two or more of these mini wheels can also be used for fine-controlling mobile robot movement
