R2 and dealing with a somber reality

This weekend, me and R2 was in Gothenburg for the annual Sci-Fi exhibition. We did arrive one day early in order to visit Drottning Silvias Children’s Hospital, a division of Sahlgrenska in Gothenburg.

Getting there turned out to be harder than anticipated. Seems Sahlgrenska, who I thought was just one hospital, actually have three hospitals in Gothenburg, and naturally we went to the main one, unloaded R2, and started looking for our friends from Nordic Garrison that was going to be there as well.

It soon dawned on us that we were at the wrong place!
R2 did meet a couple of kids visiting, but we loaded him up and went as fast as we could to the *proper* hospital where we were supposed to be, just to find out that the main event with meet and greet for Star Wars characters was over.

However, R2 had a different agenda.
He had been specifically requested to meet a young boy who has a major heart condition.

After wiping R2 off with rubbing alcohol, R2 and I went through the double sets of doors that served to block external bacteria from entering the room where the kid was.

We entered into a room filled with all sorts of electronics and this young boy, sitting in a chair. A distinct scar on his torso served as witness to past surgery. This kid had been here a while.

Meeting sick children like this really is a humbling experience. It reminds us, or at least me, of why we do these things. Normally when we are out doing photo shoots for charity, we only see healthy kids. Kids that are allowed to be just kids.

But some kids do not have that luxury. Some kids spend their day being focused on just getting through the day.

I have done a few things like this before, and it is always something that gets to you. You know you are doing good, but it is hard to feel really good inside afterwards. You can’t help but getting emotional. It is hard not to feel sympathy for the person. The kid that is not allowed to be just a kid.

At least, when I visit a children’s hospital like this with R2, it allows the kids to forget about their illness, if only for a minute. To allow them to be “just kids” for a little while. To bring a smile to their faces that should be a natural thing for kids their age, but only comes now and then and far too infrequent.

It is always with a hint of sadness that I leave children like that. Kids, that spend too much time struggling to sit up. To eat. To find something to smile about.

I always feel like there could be so much more I could do. That I don’t do enough. But at least I’ve provided a short escape for them, if only for a few minutes.

Or as the nurse working there told me: “It was a long time ago we saw him, his father and grandmother all smile at the same time.”

I wish I could do more.

I wish it wasn’t neccessary.

Bowling for Barncancerfonden

During thursday and wednesday right before easter, Me and R2 and a heap of friends from the 501st helped out in collecting money for the Child Cancer Fund in Sweden.

R2 met a lot of friends, as usual, and once we were done for the day, we stomped off to O’Leary’s to go bowling with R2.

The crew at O’Leary’s was great, played Star Wars music while we bowled, and sponsored us with the bowling fee!

Great fun, Great people! =)

Oh, that’s me on the far right, by the way.

R2 electronics upgrade

Hello! =)

I will update about the big event in Stockholm, and also about the charity event I did with R2 on Christmas Eve shortly.

In brief: R2 and the 501st collected a lot of money to battle children’s cancer in early December, and on Christmas Eve, I took R2 with me to visit poor children in Stockholm to give them a happier Christmas.

I managed to get a few 501st friends and a magician with me to help out with this. Kudos to them!

Anyway, back to what this update is about!

After the Sci Fi convention, I decided to work on my new controller again, and it has gone great!

This is my old electronics board. Well. Was.

I removed all components and started installing components on the new board..

IMG_7630

Three layers worth of circuit boards, 3 Arduino computers.. and more to come!

IMG_7635

Complete with two motor controllers, one sip ring connector board..

IMG_7637

Many of the cables are run on the backside in order to keep the front as clear as possible.

All ground connectors are run through the aluminium plate, by the way.

This is the arm controller that I’ve been working on. I will change it some more, but for now, this is what I can do.

I will draw a better version in my CAD software and send it to Shapeways to print for me in plastic! That will be sweet!

This is still a “beta” but it is really getting a lot better!

Plenty of boars inside. The curved piece was made from styrene with a blowtorch.

It sits great on the arm…

And it even works!

Since this beta, I’ve replaced the touch screen, which had a crack through it, and been working hard on the code for the controller.

This is what the controller touch screen looked like before I started:

A fairly easy way with text. Nothing fancy.

However, it turned out to be quite hard to actually touch those lines, as they are really thin, and my fingers are .. well .. not.

So, after spending a good couple of hours with my head into the code, this is what I’ve made it to look like instead:

And when moving to another page..

… and when you select an item, this is what it does now:

In addition to that, I’ve done many tweaks when it comes to things like speed, motor controllers, dome control, and the sound effects for the dome.

When I started with this controller, I was not happy with the level of control I had over my robot, but after tweaking the code and changing things around, it really starts coming together in a way that I am really happy with!

Next step is to design the proper arm holder and draw it up in my CAD software!

Stay tuned! =)
