samplerz.com Omnidirectional wheels, also known as mecanum wheels, are commonly used in robotics to enable movement in any direction without changing the robot's orientation. These wheels consist of a series of rollers attached at an angle around the circumference, allowing a robot to move forward, backward, sideways, and diagonally with precise control. An example of this technology is found in the Killough platform, a robot design that utilizes three omnidirectional wheels to achieve smooth multidirectional mobility. In practical applications, omnidirectional wheels improve maneuverability in tight spaces and complex environments, making them ideal for service robots and automated guided vehicles (AGVs). The Sphero robot ball is another example using similar principles, although it employs internal omnidirectional mechanisms rather than external wheels. Data from robotic mobility studies show that omnidirectional wheels enhance navigation efficiency by reducing the need for turning maneuvers, thereby increasing operational speed and accuracy.
