The LifeTrac open source Tractor is our weak link in the OSE Christmas Gift to the World for 2011. As we prepare to publish the Civilization Starter Kit DVD v0.01, we will include a Beta release of Prototype IV of LifeTrac, and Full Product Release of The Liberator open source CEB press, Soil Pulverizer, and Power Cube. We have gone trough 3 prototypes of LifeTrac at Factor e Farm, and we need to go to Prototype IV to address the outstanding wheel drive issues and loader balance corrections.
On the wheel drive, we are now working on quick release wheels – where a cam mechanism and 1-2 bolts allow you to take off entire wheel assemblies on LifeTrac – in under 5 minutes. This is a great step forward on LifeTrac’s direction as the world’s first life-size Lego tractor. We have already shown quick interchange power units, design-for-disasssembly (bolt-togeter) construction, interchangeability of motors, and quick-connect implements.
The concept design is a monolitic assembly with motor, bearings, and shaft – that can be taken right off the existing frame – by loosening a bolt and releasing a cam lock:
