General
- Modularize modularize modularize. 6 main modules make up all 5 heavy machines.
- This means Contract First Design. This is part of Extreme Manufacturing.
- Consider DfD.
- Consider DfF. Lengths in units of 1' for simplicity
Microtrac
- Cross stagger the wheels
- Make XYZ corner on top of frame
- Make microtrac tracks longer so there is a lower number of them
- Use 1" instead of 3" pivot
- Make gap between the wheel unit mount 4" wide
Truck + Dozer
- Close off bed of Truck - needs a gate
- Make pivot supported by 4 corners of Frame Module
- Modularize cab
- Modularize pivot unit - right now it's one with 2 degrees of freedom - make 2 with 1 degree of freedom for modularity.
- modularize engine unit in truck
- Need tight clamp-on wheel mounts hubs - with Keyway - truck
Example:
