3/2/2014 Week 2: Preparation for Hub City Regional

Today was the last meeting day before heading off for the Hub City Regional.  We went ahead and made a list of what was needed in terms of changes made on the practice robot since the competition robot was bagged.

Shooter

While the winch was almost entirely changed yesterday, we went ahead and got to test the newly built winch, as it now had the two CIM motors as well as the new yellow strap.  As expected, everything worked as needed, and the winch operated smoothly.  Again, from the way it was wrapped, everything went as it was supposed to, and it worked until the battery would dip below 12 when inactive.

Things to do with the shooter once we get to Lubbock
-Change out winch motors
-Rewire winch motors
-Replace Kevlar rope with yellow strap
-Attach the surgical tubing

To summarize the above, replace everything on the shooter except for the structure/shooter itself (replace the actuators)

Intake

Today, as before, the intake worked decently, and, while the intake was not really tested much with the larger overinflated balls, we found it shouldn't be that much of a problem due to the gearing/the intake motors should not stall at all (nice to have it 25:1).

-Change the gearing on the intake motor to the 25:1

Drive Base

As we had to take out the motors from the gearboxes to put in the winch, we had to take those mini CIMs previously on the winch and put them into the gearboxes for the drive base.  This happened yesterday, and, as before, not much difference was made in the driving as a whole, just not quite the same amount of acceleration.

-Change out the CIMs and mini CIMs with the winch

Catcher

Today was the first day in a while of getting back to the catcher in a while.  After seeing what many teams did, we figured all we needed was some sort of extension upwards, and angle it downward to bounce the ball into the robot.  Before, we tried playing around with plywood, but that seemed a little odd to mount at an angle that we would have wanted, so we went to what we used before, conduit.  Pretty much, all we had to do was bend the conduit to be mounted on the tower bars supporting the top bar (the bar that holds the surgical tubing), so it looked like a large rectangle on top of the robot.  We went ahead and mounted it to the robot using hose clamps, since it wouldn't be hit too hard, and angled it slightly downward, and added strap so that the ball couldn't go through.  Overall, it worked extremely well, and bounced the ball straight down into the robot, which is exactly what is needed.  While it may not be what was thought of in the beginning of the year, it was useful at least to me as a human player, where I could just hit the target/catcher, and know it was going into the robot.

Things to do with the catcher once we get to Lubbock
-Mount it on the robot

Approximate times of working: 12:00 PM - 6:00 PM
