Dragon*Con
#1
I’m bringing R2-D2 to Dragon*Con this weekend (Thursday to Monday).  If anyone is going to be there I’d love to meet up and geek out on droid building. I think I’ll be hanging out on the Marriot main floor and the Hyatt lobby mostly.  Send me a message or respond here.

Looks like R2 makes a terrible wing man.

So after four days of intense R2ing, I have some observations.

First, I am happy to report that my updated drive units did not overheat and R2 was able to navigate the hard surface of the con very well.  However, he HATES carpet.  I will work on making him more carpet friendly.  I talked to another R2 build who had "foot Locks" (these are in Mr. Baddeley's design but I did not know what they were for).  These locks prevent the feet from twisting when you accelerate and allow better performance on carpet.  Also, I am going to wire my six 8000mHr LiPos so they provide more capacity.  I was able to go over six hours with three of them.  (One 12V and two in series for 24 V).  So I will bridge them so I have 16000mHr in 12V and 24V. I had them wired so I could switch to a backup.  However, I found that I could go all day with three.  I figure I could get more available amps if I merged them.

Second, I burned out three of my cheap Amazon SG90 clone servos.  I will replace them all with MG90s.  They are metal geared versions of the same servo.  Hopefully, they will be more robust.  The SG90s cost about $2 a piece and the replacement MG90s are about $4 a piece.  I hope I don't need to upgrade to $10 a servo as my droid has 15 of micro servos. The bigger servos worked fine (there are four of them).

Third, I found I needed more interaction commands.  I tended to hide in the crowd and Have R2 approach people who called out to him(which happened a LOT).  Since I use the SHADOW-MD system, they had NO IDEA who was in control of the droid and to them he seems to be alive. They would ask questions and the only sure-fire response was shaking his head back and both for a "NO" answer.  I did not have a good "YES" response.  So, I will be working on a "YES" and some more ambiguous "magic 8-Ball" type answers to questions.  One of my favorite moments was when a little boy asked R2 a question and I hit a generic bleep-bloop response and he turned to his mom and exclaimed "What did he say!?"

I cannot not adequately describe how much FUN it was to make R2 come alive in a crowd of people.  I would stand next to someone for five minutes and talk to them about how alive he seemed as he was interacting with other people/kids and debate as to who or how he was being controlled. Then, I would reveal it was me the whole time!  People were literally looking overhead for drones or trying to peer inside to see if someone was inside.  This never got old!

Yeah, he is an attention hog!

I must have missed this post when you put it up. Looks like you had heaps of fun with R2 and lots of people enjoyed seeing him.

I didn't think it possible but one of those droids was possibly too weathered!? I'm surprised he didn't have Dagobah swamp dripping off him onto the carpet.

Do you think the ankle control bars that are part of the 2-3-2 system would fix the ankle twisting on carpet problem, or is it his front foot that is the problem?
