More Detail

More specifically, we uncovered many specific points that need to be verified and improved from the Bulldozer_Roadmap:

Clamp collars for idlers - field performance and slippage? Requires SME review, calculations, and field data.
Clamp collars for drive sprocket - what is the torque limit for the clamp collar in practice? Needs data collection and field verification.
A way to remove bolting conflicts and bolt heads protruding on surfaces that can be used for attaching other modules. Feasibility of partial XYZ bolting on corners to remove bolt heads is one strategy. Bolt conflicts were catastrophic in the August build - in that they forced different locations of
Cab bolt conflicts did not allow solid mounting of cab on Power Cube. Better mounting with improved tipping balance should be explored.
Series hydraulic system only was functional in the initial build - because 2 separate 1 spool valves downstream of one another function as a series circuit for the 2 wheel motors.
Little space remains currently for putting on aggressive treads
Machine height is almost too large for MicroTrac. This does call for a smaller width of the base once we are capable of building our own hydraulic wheel motors. Currently, they are a stopgap measure.
