LifeTrac Tractor

Overview

LifeTrac is a low-cost, multipurpose open source tractor. It serves as a workhorse backbone for many of GVCS technologies.

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.

Four hydraulic motors provide skid steer power to the wheels, and a unique chain tread system enables navigation of fairly extreme terrain.

Status

Currently the Lifetrac is on its second prototype with half a dozen units at Factor e Farm. The machines are currently being prepared for field testing as a part of the Factor e Farm Infrastructure Buildout 2011.

The next prototype aims to integrate as aspects of Digital Fabrication for automated production. Rebar construction is also under consideration.
