This project builds on the success of our Microtrac prototype, which forms the base module of the Bulldozer. You can get a taste of how we built it, download the CAD file, and see the results (moving 8,000 lbs in an initial test).
The OSE Bulldozer is:
Fully Open Source
- collaborative design, anyone can contribute
- full documentation released, including detailed instructionals that make replication a realistic option
- CC-BY-SA license
Meets or exceeds industry standards
- 18,000 lb torque
- 4.4 mph speed
- 168 hp
- for scalability: 2,000lb Microtractor base module is stacked to make a 13,000lb bulldozer
- for flexibility: add or exchange modules
- for interoperability: modules are shared by other machines in the GVCS
- the PowerCube engine module can be built to run on any fuel
- we've already prototyped a charcoal gasifier which has successfully run the PowerCube on pyrolysed biomass from our farm
Easy to fabricate
- designed for manufacture with a minimal tool set
- built from simple assemblies of off-the-shelf parts
Designed for lifetime use
- all modules are accessible for repair or replacement.
- bolt-together, easily disassembled construction
- unlimited potential to add new modules
- designed for easy attachment of new tools and functions anywhere on the machine
Part of a whole ecology of tools
- The GVCS includes Open Source versions of machines that can build the bulldozer, as well as tools that complement its functionality.
- For example: our Metalworker lowers the cost of building the Bulldozer. The Bulldozer can grade a foundation site for a building, then the Compressed Earth Brick Press creates the walls of the building from on-site soil. All of these tools are powered by the same PowerCube module.
We publish our design work online as we go - you can follow along on these two Google Docs:
