1 Full system check.


2  Manupulator exchange.

Evaluate the six nuts and bolts that hold the Wrist to the Arm to see if larger ones can replace the existing.
If needed. Prepair the larger nuts and bolts before disassembeling anything. Lock nuts or lock washers or locktight will be needed.
Select a clearance drill for the bolts that will be used and chuck into a drill.
Mark the shims that are between the Wrist Arm Side and the Arm so that you can tell Robot Right from Robot Left and Front from Back.
Disconnect all wires and carefully pull them away from wrist area.
Remove six nuts and bolts from Wrist Arm Side and save.
Carefull remove Manipulator #1 from arm and keep track of shims (Place them in a preplanned positon).
Use the shims to draw the hole pattern on Manipulator #2, be extreemly carefull to keep the orientation correct.
Use the drawn holes to "transfer" holes to the new manipulator.

Measure the manipulator position relative to the Frame Perimiter. Remember the frame perimiter is ………..
Remember the frame perimiter is;

So where our frame "sunk in" during welding does not count.
It's a straight line from corner to corner projected vertically that determines the frame perimeter.








At FLR

1 Put bolts in the corners of the upper structure

2 Put on chain guard

3 Put on minibot roof

Before FLR

1 Order spare parts from Harris

2 Redesign manipulator wheel shafts for maintainability

3 Design chain guard

4 Design manipulator wheel guard 

5 Design minibot roof and backstop


Complete;

1 Order McmasterCarr parts
