Holonomic Platform for 125mm Rotacaster Omniwheels
I’ve been working on a very solid, Holonomic Platform to be used with the large 125mm Rotacaster Omniwheels as part of my display for the TAZ-Brick Collector Club’s Brixhibition to be held on the weekend of 20-21 April 2013.

This Holonomic Platform is built around a very solid “Triangle” arrangement constructed from LEGO 1 x 16 Technic Brick with the Holes in them and LEGO Hinges (Part #2429c01 1 x 4 Hinge Plate). This Triangle arrangement also allows for easy, yet solid addition of the other LEGO components need to complete the robot.

Over the past few years I have developed a number of Holonomic Platforms of various sizes and configurations, but this by far the most stable in construction. It even survived the drop test after I tripped over the PlayStation 2 controller cable attached to it. It will need to tough and reliable to survive Brixhibition.
