Mecanum Wheels

Omnidirectional drive systems are a great way to maneuver your robot in tight spaces. Mecanum wheels combine the simplicity of a differential “tank” style drive system with the omnidirectional maneuverability of omni-wheels.Here’s a video of a Mecanum-driven electric wheelchair. Not a robot, but the video does a good job of showing how the wheels work.http://auto.pege.org/2006-ever-monaco/rollstuhl.wmvIf you want to buy some Mecanum wheels (and you should), head on over to AndyMark and check them out.http://andymark.biz/mecanum.htm

Featured Robot: “Helios”

This is Helios:

Helios will show you much pain.

This wrecking machine, brought to you by the fine people at Team Cosmos, utilizes a surprizingly simple and effective weapon. A spinning drum with ridges that catch under the edge of an oponent and litterally pitch it up into the air.

I know this bot isn’t exactly new, but once I saw this video of Helios in action, I knew we had to give it the spotlight.
