Tasks to Complete

Washington Thursday

1. Full system check.

2. Manipulator 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. Prepare the larger nuts and bolts before disassembling anything. Lock nuts or lock washers or lock tight 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.
Careful remove Manipulator #1 from arm and keep track of shims (Place them in a preplanned position).
Use the shims to draw the hole pattern on Manipulator #2, be extremely careful to keep the orientation correct.
Use the drawn holes to "transfer" holes to the new manipulator.
Drill the bolt holes into the Manipulator #2 and reattach.
Reconnect wires with electrical guidance.

Measure the manipulator position relative to the Frame Perimeter. Remember the frame perimeter is ………..
Remember the frame perimeter is;

3. Driver practice and matches.

4.  Minibot nest exchange evaluation and prep work.
