[[LifeTrac]] is a low-cost, multipurpose open source tractor. It serves as a workhorse backbone for many of GVCS technologies. Prototype III stage has been completed, and field testing determined the need for Prototype IV prior to product release. &lt;br /&gt;
&lt;br /&gt;
Featuring a modular design and detachable [[PowerCube]] units, it has the ability to rapidly switch between a variety of GVCS machines via the [[QA Plate]]. The machine is overbuilt with a focus on lifetime design and ease of repair.&lt;br /&gt;
