Repairs & Modifications Following PARC XIII
10-May-2010
The Pivots received a thorough overhaul last night and should be good for Monty Madness this Saturday. We replaced a blown bearing (a spacer had been mis-installed), realigned Transfer Axles and Wheels and tightened all set screws on the Transfer Axles (replacing a couple set screws which went missing). Out of the two swapped-out Pivots, we assembled one working spare Pivot in good condition and ready for use.
The left side Ball Dam Gussett was badly bent in at the bottom. This would have required a considerable impact. Our PARC Pivot failure was on Pivot #3, also in the front left corner, so one hypothesis for the failure is a greater than normal impact to this corner of the robot during PARC Q1. A second hypothesis is that the Pivot which failed was the one with the loosest fit between the Pivot Tube and Pivot Plate (this loose fit was noted during assembly). The bent Ball Dam Gussett was straightened.
A weld inspection revealed no new broken welds. The known broken weld was not repaired.
The 1" Angle frame top elements are all noticeably bent inwards due to competition impacts. Square tubes would have been a better choice (angles were used for weight & Center-of-Mass management).
Latch wire ties were gone. Replaced.
Agreed on IR sensor (2Y0A21 F) mounting position (for sensing that the ball is in kicking position). We'll mount this on Wednesday.
Added side-ramps onto the goal ramp to better match the field geometry (and reduce wear and tear on the robot drive-train).
On Wednesday, we will mount the IR sensor and wire the Accelerometer.
Time permitting, we'll switch more wheel tread mounts over to the Deaver system.
