Build Yourself. Build Your World.

The Open Source Ecology Eco-Tractor workshop is an immersion experience where we will build a working tractor - and more - over a weekend:

A Microtractor: A 32 hp, tracked machine that is similar in functionality to a Toro Dingo brand utility machine but is more powerful. Because our build system is modular, we will add a second power Cube to this tractor for a total of 32 hp for more demanding tasks.

<img src="http://opensourceecology.org/wp-content/uploads/2017/09/mt3.jpg" alt="" width="550" height="400" class="alignnone size-full wp-image-9732" />

Tractor: A 64 hp tractor that consists of 2 of the Microtractor units combined together. As the first team works on the Microtractor, a second team will work on a wider version of the tractor for the second 32 hp half. The 64 hp combination tracor will feature articulated steering, where the tractor bends in the middle to turn. The 64 hp tractor will be designed with a quick attach such that either the larger tractor - or 2 of the smaller tractors - can be used as needed.

Solar Module: The beauty of hydraulic power which we use to drive the tractor is that a small power source can still move a heavy machine - only slower. Thus, a 2000 lb tractor can still move - and with as much force - on a single solar panel. As such, we will use a solar panel to run a small electric Power Cube - which then can run the tractor. This will be our proof of concept that a tractor can do useful operations on solar power - shining new light on the capacity of solar power to fuel agriculture. This leads to automation.

Automation Module: Another advantage of hydraulics is that they can be controlled easily via solenoid valves and controllers - in addition to manual control. As such, we will program a controller to drive the tractor autonomously. The first proof of concept will be the tractor driving autonomously in a simple pattern - using an Arduino controller. If time allows, we will implement an automated guidance system with feedback from the environment for avoiding obstacles.

If more than 18 people sign up for the workshop, then we will also build a:

Charcoal Power Module: Did you know that a gasoline engine can run on charcoal? We will be improving upon the last year's prototype to build a second iteration of a gasifier. The gasifier produces gas from charcoal to fuel the Microtractor. We will mount the gasifier on the tractor, and fuel the tractor with charcoal gas via the air intake. This will demonstrate that our tractor can run on biomass-derived charcoal, which is a renewable form of energy - relevant in areas where biomass is abundant.

Here is some prior work from 2 years ago. The largest machine that we built was 71 hp so far. We did not yet build the 164 hp machine discussed in the video: <iframe width="560" height="315" src="https://www.youtube.com/embed/dGp4zrRpEs8" frameborder="0" allowfullscreen></iframe> Some of the specifications are:

The design focuses on minimizing part count and integrating the design with other machines of the Global Village Construction Set (GVCS). As such, we are using Nema 17 stepper motors and 6mm GT2 belt - the same as on our 3D printer. This pushes the limits of modularity and scalabilility - reducing overall GVCS parts count significantly. See one of the 5' axes being built - [embed]https://www.youtube.com/watch?v=JOH03vzDYQg[/embed] We will be using this type of carriage with metal plates to provide rigidity while allowing the use of 3D printed parts: <img src="http://opensourceecology.org/wp-content/uploads/2017/09/carraoge.jpg" alt="" width="1000" height="638" class="alignnone size-full wp-image-9703" /> A Scalable, Modular Construction Set for Tractors Construction Set Design To create a Construction Set - we designed a small set of modules that can be reconfigured. The core parts include power cubes, the Universal Rotor, tracks, frames, and hydraulics modules. We are designing with the absolute simplicity in mind, such that machines can be maintained for a lifetime of use. Our parts count of about 100 unique parts for the entire tractor is lower than anything available on the market. https://www.youtube.com/watch?time_continue=5&v=q3xQtt5IZrw Using this Universal Axis and taking advantage of the Construction Set approach, we have already built a number of these machines: <img src="http://opensourceecology.org/wp-content/uploads/2014/02/tractor_3-300x206.png" alt="" width="300" height="206" class="size-medium wp-image-7717" /> Inforgraphic by Jean-Baptiste Vervaeck[/caption][caption id="attachment_8177" align="alignnone" width="300"]<img src="http://opensourceecology.org/wp-content/uploads/2014/02/pc71-300x207.jpg" alt="" width="300" height="207" class="size-medium wp-image-8177" /> Power Cube infographic.[/caption]<img src="http://opensourceecology.org/wp-content/uploads/2015/05/OSE-gasifier-2015-infographic-907x624pc-v1-6a-300x206.jpg" alt="" width="300" height="206" class="alignnone size-medium wp-image-9049" /><img src="http://opensourceecology.org/wp-content/uploads/2015/05/OSE-microtrac-2015-infographic-907x624px1-300x206.jpg" alt="" width="300" height="206" class="alignnone size-medium wp-image-8986" /> Lowest Unique Part Count in the World The beauty lies in an absolute minimum number of parts that can be used to build an infinite variety of heavy machines - depending on size, axis configuration, and implements heads. The unique part count is in general around only 100 parts, which is about 5 times less than anything available commercially. By making our machines simple and universal, we are aiming for the most widely replicated tractor construction set in the world. There are no constructio sets for tractors out there yet. To that end, we are inviting developers and entrepreneurs to join the <a href="http://opensourceecology.org/wiki/OSE_Developers">OSE Development Team</a>. This workshop intends build upon OSE's <a href="http://opensourceecology.org/wiki/Extreme_Manufacturing">Extreme Manufacturing</a> approach of rapid building with multiple teams working in parallel on modular components. By simplifying the design and streamlining the build with digitally-fabricated, open source parts - we intend to develop a model where several of our tractors can be produced in a single day by a team of people. Our goal is to develop open source microfactories for distributed production - using the Experience Economy and Social Production. We are also developing an open source enterprise model for how to run extreme build workshops anywhere in the world. We are publishing our enterprise model openly, with all supporting information that helps people in a successful startup - without reinventing the wheel. We will also be offering 6 week immersion training where strong candidates can learn to replicate our workshops to start a small business. Workshop Expectations This workshop is experimental, and not a turnkey product. We have significant experience with the topics covered, but surprises always come up in an experimental build. We have thorough CAD documentation of the machine. We have built 10 prototype tractors already. But surprises do come up in ambitious builds like ours. No matter what - we will build it - and we will drive it. Whether we complete the solar drive option, the charcoal fuel option (gasifier), and the computer vision - is up to us. [embed]https://vimeo.com/23785186[/embed] While we have done extensive design work, and prototyped the different parts - this workshop is a first complete build. Expect to problem solve - and learn a lot in the process. This is an immersion learning experience in design and build. The worst case achievement scenario would be that we get the automated machine going in the xy plane - so we an cut steel with it, but we may not have the torch height controller installed, nor automatic gas turn-on so that the oxygen will have to be turned on manually for cutting metal. In the ideal scenario, we will implement fully automatic control, including height control, automatic gas turn-on, and automatic flame ignition. We will practice cutting on sample 1/4" and 1/2" thick steel. The first day covers use of FreeCAD, and explanation of the design rationale for the CNC torch including all its components, and why we made the choices that we did. We will teach participants the basics of FreeCAD - literacy in manipulating 3D objects as well as modifying their geometry. We will provide an introduction to KiCad for electronics design - of the CNC torch height controller. We will have 2-4 3D printers printing during the workshop to produce additional parts (cable chain + other parts). How far will we get to completion? It's up to us. The risk factors are system integration from proven parts. If you want an immersion lesson in FreeCAD, please make sure to download the <a href="http://opensourceecology.org/wiki/OSE_Linux">OSE Linux</a>, which can be run on your computer from a USB stick without interfering with your operating system. This Linux has the FreeCAD and other software that is necessary to work with the CNC torch table. If you use the OSE Linux, it will be guaranteed that there are no software issues getting in the way of your learning. While we do not require prior skill to join this workshop - the more skill that we have in the team of participants, the better will be the result. We expect people to work together as a team for a common goal, and we like it when participants teach one another new skills. For development work, we invite our participants to join our <a href="http://opensourceecology.org/wiki/OSE%20Developers">development team</a>. During the workshop itself - expect to do some problem solving - as building a machine of high complexity typically has surprises. The intended audience for this workshop is hackers - people who want to get their hands dirty - who are interested in the design and build of hardware. The intended audience is anyone interested in exploring the meaning of Open Source Product Development. We've been pioneering techniques of collaborative development for several years. But be prepared - this is not for the faint-hearted. Our facility is raw and crude - a farm in the middle of nowhere, Missouri. By attending, you are helping us carry out our open source development mission. Bring a Friend for Free We also have a 2-for-1 offer . You are welcome to bring one friend or family member with you for free.

Participants become engaged in a part of OSE’s development process, where we produce open source blueprints for the infrastructures of civilization. Participants are introduced to basic principles of collaborative literacy - how the collaborative mindset can be used to solve wicked problems. This workshop is intended for people interested in immersion, hands-on skills training and practical results. We are especially seeking participants with an entrepreneurial mindset to expand open source production into the mainstream. We are exploring the potential of open source economics by determining the limits of social production: can distributed, collaborative, community supported manufacturing (CSM) be an alternative to centralized factories? The overall workshop is designed for people interested in transitioning from consumer to producer. We welcome both complete novices and those with experience. The critical part is willingness to learn. By joining this workshop, you have an opportunity to be part of a community interested in developing products collaboratively and open source, so that everyone can benefit. OSE's goal is to promote right livelihood using open source - and part of that is starting enterprises. We are promoting the concept of <a href="http://opensourceecology.org/wiki/Distributive_Enterprise">distributive enterprise</a>. Have questions? Drop us an email: info at opensourceecology dot org
