HiTechnic Rotacaster 2-Pack

The HiTechnic Rotacaster multi-directional wheel is perfect for creating robots that can move in any direction. Your robot can go forward, backward and sideways or any direction in between by using three or four Rotacaster wheels. The Rotacaster wheel is also an excellent alternative to a caster wheel since it can roll in any direction. With a compatible cross axle hub these wheels can be easily built into your MINDSTORMS® and Technic models. The wheel is manufactured with low friction rollers to ensure easy movement in any direction. Note: Photo shows a single wheel. This 2-Pack contains two Rotacaster wheels.

Introduction

These 48mm Rotacaster wheels have eight polyurethane rollers that allow them to freely roll sideways as well as roll forward or backward like a normal wheel. This special wheel has several possible applications on robots.

Unlike a traditional caster that has to be mounted on a vertical axis to allow turning, the Rotacaster wheel can simply be mounted like a regular wheel. Not only is this much easier to build with, it also makes your robot more accurate since the wheel does not interfere with robot driving and turning.

se on a Holonomic Driving Base

A holonomic robot is a robot that can drive in any direction independent of the direction it is facing and can even turn while driving. These robots, sometimes called OmniBots, are usually built using three wheels with each wheel mounted 120 degrees from the others. Here is the HiTechnic RotaBot:
