Aside from the chassis a large hexapod will be able to be built from off the shelf components. The ASB-06 and HUB-08 and tubes etc, can be used to make larger versions of the A style 3DOF legs.

Brushed finish parts have a release date of 2-29-08 and the anodized parts have a release date of 3-12-08. It will take a little time after we receive them to get them packaged with hardware and set up on the website for sale. The price will not be too much higher than the standard size parts, just a little. 8)
