Review

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
