Attendance: Ian, Tucker, Penelope
Agenda:
Fix the robot
test the robot in the arena
work on software
We had two split clamps that had to be swapped out for ones with set screws on the pipe connecting a couple of our axles. To do that we had to take the whole arm structure off and take the tube out. Fixing this only caused more problems, first it was those two clamps slipping but they couldn't with the set screws. The tube started slipping in its clamps. During this progress, we took the robot to the feild to test it at various points of "completeness". We managed to score some points but fell over and bent some peices when we tried to fold the arm up. During the testing we realized the tubes were slipping and came up with an alternate design that used stand-offs and C channel to replace it. We finished rebuilding the drive train for the first stage of the arm with this design (though we had to take the arms off again); We did not have time to replace the tube on the second stage of the arm, though we started and decided to reduce the gearing to 6:1 from 4:1.
Penelope spent most of the day helping 267 work on their bot because they only had one team member at the scrimmage today.
We got the servos for the dump bed all wired up today and they work great. we added a fourth servo recently to increase the power of the arm by 1/3. The servos now use three servo ports instead of just two, we had the three dump servos chained with Y cables to one port but were concerned about how much power we would be able to draw from one port. Now there are two ports that have Y cables for the dump bed, and one that controls the gate.
