LifeTrac Research Questions

LifeTrac is an open source, design-for disassembly tractor with interchangeable modules and a high level of flexibility that aims at achieving a life-size Lego set for mechanical equipment and implements. There is a number of research questions to be answered:


 * 1) What is the optimal frame design such that it can allow for attaching all the different modules and components? What are the design requirements for the frame that would allow it to be a 'life-size Erector Set'? What is the optimal structural member unit for the frame? We are presently using 4"x4"x1/4" steel tubing.
 * 2) What is the maximum practical size for the frame, and therefore, tractor?
 * 3) What is the best design for the PowerCube? What are the design requirements for a PowerCube?
 * 4) What is the minimum power that a highly functional tractor requires? What is the minimum size that LifeTrac can be?
 * 5) What modules can be added to the tractor? How can the modules themselves be modular, ie., consist of a number of smaller design-for-disassembly modules?
 * 6) What is the best design for a modern steam engine-based PowerCube, such that any biomass crop (biomass pellets) can be used for fuel?
 * 7) What is the best design for a biomass pelletizer system that could be used to produce fuel for the tractor?
 * 8) What are the design requirements for the tractor to have lifetime design?
 * 9) What is the cost analysis for parts, components, and labor of producing the tractor?
 * 10) What are the fabrication requirements and ergonomics for a tractor production enterprise for LifeTrac?
 * 11) How can an induction furnace be used to produce parts for the tractor out of scrap steel?
 * 12) What machining requirements exist for making components for the tractor, if one were to not buy parts off-shelf?
 * 13) What is the best design of a universal, quick attach plate for the front loader for attaching implements?
 * 14) What are the weight balance issues involved?
 * 15) What is the structural analysis for the tractor - what are the maximum loads it can carry on the quick attach and loader?
 * 16) What are the power and structural calculations for the tractor?
