Star Wars Night at Dodger Stadium - 2019

Today R2 participated in Star Wars Night at Dodger Stadium, along with many other characters from the Star Wars costuming clubs.



As I had mentioned in today's earlier CHOC post, droid #1 was having some drivetrain issues, so droid #2 was called into service for this one, and he performed admirably. Nice to see a clean droid again!



I arrived and unloaded, and stationed R2 outside the changing room, where early-arriving fans took pictures.




We were split up into four groups of diverse characters. My group was to be stationed in the right field plaza to greet arriving fans, and at 6:00pm we were to be taken down onto the field.

At 4:45pm we headed out and waited for the gates to open.



And once they did open, a line instantly formed for pictures.





We cut the line off a little before 6:00pm so that we could relocate down onto the field. While the other characters can take the stairs, R2 must take the elevator. We made a quick stop by the World Series trophies on our way.



And when there's not an elevator, the chair lift will have to do.



Because we end up slightly below field level, I take R2 on the wheelchair elevator to get up to the field. This is my view as the roof-less elevator approaches field level.



Tonight was Hyun-Jin Ryu bobblehead night, and his wife Bae Ji Hyun was to throw out the first pitch, so lots of South Korean media were there.



In the meantime, we greeted fans that were invited onto the field before the game, and posed for media photos.






Bae Ji visited with us and got some photos.



And then she went to warm up her arm with her husband, who was going to be her catcher for the first pitch.



Next, the characters helped out with the Star Wars trivia contest that was shown on the scoreboard. The screens look absolutely gorgeous in person, but the refresh rate doesn't work well with cell phone cameras.





Once we were done with the trivia contest, we retreated back to the warning track, where Hyun-Jin Ryu and his wife had some fun interacting with R2. Hyun-Jin tried covering up R2's eye to see if he could still see.





Bae Ji threw the first pitch to Hyun-Jin, as the characters looked on.



And with that, it was time to retreat around the on-deck circle and back to the changing room.





We didn't get far though, as Bae Ji was doing more interviews with the South Korean media, so we waited.



We finally made it back to the changing room, where I stowed R2 for the game, while I went to go find a Coke and pretzel.



$7.00 for a Coke?!? I'll just drink the water that I saved from the changing room, but I will have that $5.00 pretzel.



The Dodgers provided us seats, so I watched the game from our vantage point on the reserve level.



The Dodgers were down 4-3 with 2 outs in the bottom of the ninth inning, when they received five consecutive walks!! They won 5-4 in literally walk-off fashion!



I headed back to the changing room to fetch R2, although I wasn't going anywhere for about an hour, as I needed to let the crowd thin out before even thinking about taking him to the parking lot, otherwise I'd be mobbed. In the meantime, the ball girls (in uniform) stopped by for a picture with R2, as did several outbound fans.



R2's record is an outstanding 9-2 with the Dodgers. As always, I am very grateful for the opportunity to combine my Star Wars fandom with my Dodgers fandom, and I hope to be back next year as well. The full photoset is here.


CHOC Summer Visit - 2019

Today R2 joined several members of the 501st Garrison for a visit to CHOC, to bring some Star Wars fun to the young patients there.



We did room-to-room (and occasional hallway) visits. As usual, no pictures with the young patients, but they were happy to see us.





About 2/3 into our visit, R2 started acting squirrely, in that his left foot motor was having trouble running. When I got home, I tried swapping several components - batteries, speed controller, transmitter, receiver, and I bypassed the solid state relay kill switch, but nothing seemed to resolve the problem. This lead me to believe the problem was either the motor itself, or the drivetrain.

I didn't have time to look into the problem further, as I had to get ready for Star Wars Night at Dodger Stadium. Given the state droid #1 was in, I would have to press droid #2 into service. #2, you're up!

Cut Yet Another Ankle Lock for Left Ankle

Back on May 4, 2019, I had cut a new ankle lock for the left ankle, as the previous one wasn't doing the job. Well, this one wasn't doing the job either (it also had a tendency to spin around). So, third try's the charm?

I was determined to get it right this time. I started by making a paper template.




I translated the paper template to the cutting board I've been using for the ankle locks, and cut the piece to size.





I then did a test fit. I'm ok with between a 1 and 2 mm gap between the foot shell and the bottom of the ankle lock. Here, the ankle lock is resting on the foot shell, so the gap is on top.



The next question is, where to drill the mounting hole? The hole has to be located such that a screw driver can reach around the motor. I (foolishly) convinced myself the upper left was the way to go.



But when I mounted the ankle lock and screwed it down, I found that I still couldn't quite reach around the motor. This shows the lock mounted, but not the motor being in the way.



So I had to drill a new hole on the opposite corner, which was accessible with a screwdriver.



I did a lot of test driving with this new ankle lock, and it really looks like it's going to work this time.

Robotics Society of Southern California Presentation at Cal State Long Beach

Today I was invited to California State University Long Beach to give a talk to the Robotics Society of Southern California about R2.



I arrived around 10:20am for my 11:00am presentation in the Engineering Technology building.



I unloaded the Droidmobile and brought R2 and some his gadgets to the classroom, where another robotics presentation was under way.



I gave a presentation that covered the R2 Builders Club in general, and my build in particular, and I demonstrated some of R2's capabilities, such as the mist effect, dome and sound automation, and flag wave circuit, among other things.

Afterward, I invited those in attendance to take a look inside R2. We also had good questions, and it was nice presenting to an audience that really understood a lot of what goes into making a robot come to life.

CHOC Festival of Life

Today R2 helped CHOC celebrate their Festival of Life, along with several other characters outside the Star Wars universe.



The event was hosted in the outdoor atrium of Hyundai's building in Fountain Valley, CA.




Young patients who had survived cancer and other maladies attended, and took pictures with the characters.





Everyone had a good time, and it's always a good experience to help CHOC out.
