My design consists of two sets of wheels perpendicular to each other driven by servo motors. For control I took a Playstation 2 controler apart and used the thumbstick in stead of the two potentiometers in the "pot boxes" we used to control the arm. The script is very simple. It scales the potentiometer values from the thumbstick to add to the pulse widths for the motors

Holonomic wheels (also known as [http://en.wikipedia.org/wiki/Omni_wheel omni wheels])have rollers perpendicular to the direction of rotation. This allows them to roll normally and slide laterally.

Concept

Build a device that moves omni-directionally using holonomic or 'omni' wheels. There will be four wheels arranged around the chassis such that there are two opposing sets. The device will be controlled by an analog thumbstick salvaged from a Playstation 2 controller, and will be programmed in MatLab.

Description of Project

The final product is a “robot” that moves omni-directionally.I used holonomic wheels and continuous rotation servo motors for locomotion, and a Playstation 2 thumbstick for control.

Holonomic Wheels

Holonomic wheels (also known as omni wheels)have rollers perpendicular to the direction of rotation. This allows them to roll normally and slide laterally.
