LifeTrac II – Frame
Posted by William
We are working on the second prototype of the open source tractor, as discussed in the last post. We have come up with a sketch for the new LifeTrac II frame, which was drawn in Blender. The disks mark the location of the wheels, and the middle verticals will serve as the attachment for the 2 loaders – front and rear. The idea is to come up with the simplest, replicable, design-for-disassembly, lifetime design consistent with our specifications.
We intend to develop this sketch further until we have a fully working 3D model to reference when we come to physically building LifeTrac II in the workshop. The usefulness of Blender is to determine exact bolt locations and sizes of structural members. This is especially useful when designing the loaders and quick attach plates – where we can model the heights and angles required prior to building. You can see our initial designs from over a year ago for reference – on the evolution of the project. (more…)
