I have been working on an LEGO Mindstorms EV3 Holonomic Platform, with Dual-Wheels on each of its three sides. It is controlled via a Sony PlayStation Wireless Remote Control. The PS2 Remote interfaces to the LEGO Mindstorms EV3 Brick via Mindsensors PSP-Nx-v4 Adapter.

The Holonomic Platform is based around a very solid triangle built from 16×1 Technic Bricks and Hinges. This allows for a much sturdier base to work from when compared to using LEGO Technic Liftarms.

The Holonomic Platform relies on a set of 6x Rotacaster Robot Omni-Wheels which I helped developed in conjunction with Roatacaster Australia a few years ago. You can purchase them through the LEGO Education On-line Store, or from Rotacaster Australia directly. The Rotacaster Robot Omni-Wheels are by far the best quality on the market. Unless you intend to run over them with a Caterpillar D9 Bulldozer, you will never brake them as they were originally designed as Industrial Rollers.

The RobotC program that controls the LEGO Mindstorms EV3 Holonomic Platform is basically the same code as I use with my LEGO Mindstorms NXT based Holonomic Platforms. It has had some minor alterations that make it RobotC v4.2 Compliant.
