Since we got the drivetrain stuff yesterday, today mostly consisted of putting everything together, and worked a little on the intake. Being a Thursday, we left a little early today.
Shooter
Today, the surgical tubing arrived, so we got to begin to play with it. Although it was very thin, we observed this higher quality surgical tubing was still pretty great. After cutting the surgical tubing more than halfway, the tubing wouldn't snap when extensively stretched, and it wasn't until it was cut around 3/4 through that it started to rip the rest of the way. After playing around with the strength of the surgical tubing, we also tried to begin making the loops using a nut and bolt and soap to make it more easily go in, since the nut and bolt head were each larger than the hole, but they kept slipping out. Before we got to try a couple other methods, we had to go.
Intake
While it was figured out previously that we needed side rollers, the team went ahead and just tried playing with the intake one more time before adding side rollers. As happened before, the ball had to be hit almost spot on in order to be sucked up. While this was tested, the holding of the ball using the intake was also tested, and, happily, we found the current geometry of the intake perfectly held the ball in the robot very securely. Also, while the intake geometry allows the robot to keep the ball securely, the intake can also spit out the ball if needed, and spit it out around 10 ft. This shows the intake probably just needs the side rollers, then it'll be okay.
Drive Base
Today, the drive base was continued, and, after taking a very long time (we kept making little mistakes that would make us take apart everything, make the change, and put it all back together), we finished the drivetrain for the official practice robot. In addition to the drivetrain structurally being pretty much finished, we went ahead and laser cut a bellypan (flat surface that is the bottom/belly of the robot), and made sure it fit, and started placing electronics onto the bellypan. Primarily due to the drivetrain taking forever, this was everything we got done today for the drive base.
Approximate times of working: 3:30 PM - 7:00 PM
