Southern Builders Meeting in Orlando

Interesting experience to say the least. The drive from north georgia to orlando only took about 8 hours. Mileage for the trip was on the nose at 1000 miles.

I had a great time meeting some other r2builders. I wasn't sure if I would fit in or not, but everything went well.

Daniel was a fantastic host. Thanks for having us.

The Pictures! I am leaving the images (very)large, so they may take a few moments to load.

This is a picture of most of the builders that were present. Calvin and Christopher had already left when we got the group together for this shot.

Mark standing over a fiberglass R2, and we can also see the back of Chip's droid.

Another shot of the fiberglass R2, the Blue paint on this was fantastic.

Calvin's Dome. Mirror shine!

Mark's R2. A&A body and legs. Lots of good information about what I have infront of me in my build since I will be using the same materials.

Robart hinges at work. This droid is looking great!

Ok, Daniel had a few droids in his foyer, and I decided to take a few snapshots. This one was from something in Epcot.

Fry Bot!

Coke Bot!


A surprise guest. This is a "Special" droid.


I think someone said this was Scott's droid, but Im not sure. It looks great.

Mark brought the A&A drink tray. He wanted to try it out and since my droid was the only 2 leg at the meeting, we set it on top.




Pretty sure we all had a good time.

Stopping point

This is what my droid will look like at the Southern Builders meeting. I spent the day trying to get everything tightened up and ready for travel. The little stool isn't really needed, but because I was working on the legs at some point today, I need to get him off the ground.


I hacked together some minor electronics so dome rotation will work.


I may post a few times this week, but not sure what the content will be. I have some paint tests I need to do to figure out the Kreider method. If it doesn't rain, I may do that.

Standing!!!

Ok. didn't think this would happen today. I woke up this morning with the intention of doing more work on the legs and for some reason I picked up Kelly's resin feet, walked into my makeshift workshop and started to drill some holes.


To get my droid standing I did have to cheat a bit. There is a bit of duct tape here on some wedges cramed in between the ankle and the feet. This is to keep him from falling on his face because I don't have my legrods worked out yet.

Here is a shot of the holes I made, and the end of the bolt I used.

Sorry about the flash in this picture, but this is some of the hardware I have going on in the shoulder.


One of the legs has some styrene glued on which is why one is white and the other is not. I will get the styrene on the other leg tomorrow. Going to do a bit more work on the shoulder horseshoes and just a bit of cleanup work and it will be time to put my tools down. I won't have much time to work on my droid this week. I need to figure out what I will be taking to the Southern Builders meeting and how I can pack it all up in my car.

Leg day part 3

Legs are on.. sort of anyway.
My local Lowes has yet to restock several types of screws and bolts which I cleared from thier shelves this past week. Some things are only held on with a single bolt/screw at this time.


Started working on horshoes, but the pvc glueing technique I used on the legs didn't work as well here. This will need to be completely redone, but with the Southern Builders meeting coming up, I may just do a few small tweaks and just let it go for a while.


New ALU skins arrived.


In my rush to get some of this guy put together, I am leaving a wake of debris and parts. what a mess...

Leg day part 2

Not much to report today. I got the big 1/2 bolts installed, got the bushings installed for the shoulder motor screws, and messed around with the ankle a bit.

Got some news from Andy, that he will be doing scooter motor mounts. I will definitely be getting these, because fabricating my own has giving me nightmares... if the shoulders, ankles and motor mounts are not lined up just right one of 2 things happens:
1. The foot and leg wobble noticeably when the droid is in motion.
2. The leg breaks off.

Anyway, no new pictures.

I have managed to acquire a few spare parts during my rush to get in on part runs that do not appear to happen very often. I will be posting these for sale on r2builders to recoup some of the cost on these items.

with motor mounts pending, I am taking a hard look at these resin feet. I may go another route for feet shells.

ALU skins, and FLS should be in the mail.
Daren updated the website on the 300mm Domes on March 2nd. There was some kind of issue with the inner domes and he has taken steps to correct the problem. The target delivery date has moved up to 3/28/7. keeping my fingers crossed!

Leg day part 1

Picking up the pace a bit. Started to focus on the outer legs.
Checked some of the documentation from the group.

This is a subset of some of the screws and bolts I will be using to assemble and attach the legs to the satelite motors.

Shoulder hubs. Screwed together and glued.

I modified the channel on the A&A legs which was originally intended to be used for wires. With this channel a bit wider, I hope that I will be able to get leg rods and wiring in this slot.


Legs mostly glued up. Still a few other pieces left to glue on, but I will get to those tommorow. Need to get everything screwed and bolted together, then I can start working on making them pretty.

Its ALIVE!!!

Got the frame back together, and since the dome is coming along, I decided to throw in my vex stuff and get some movement.

The movie is about 6mb so it will take a few minutes on dialup.

In other news, The center leg is still pretty bound up. Therefore, I will be moving straight to 3 leg stance to simplify the process and actually get this guy standing.

Center Leg, Motor Mount, and Chinese New Year

Ok making some decent progress, but not as fast as needed. Errors and other issues seem to delay the completion of one component to the next.

Following up on disassembling.. I needed to rotate the shoulder motors to the top of the frame. This allows room for the drawer slides to fit properly.


Not having much mechanical engineering or construction experience led me through a process of trial and error to get these slides installed.



Getting all of this lined up and centered was a good challenge.


Saturday night, we went to a friends house for a Chinese new year party. My daughter was dressed for the occasion.


Finally finished up the paint job on the Dome ring. The dome is just resting on top in this picture. I will get this all buttoned up tomorrow.


I bought a cheap circle saw and some plywood. This is my attempt at a scratch built motor mount. This is going to take a bit more work than I anticipated, and hope it will work. I will be looking for motor mounts from the group, because I know these may not last.


Ok, back to the center leg. These pictures are actually a second run at trying to get this to work. The first attempt proved that my ability to measure stuff at 2am is a bit off. The rails were rubbing against the pvc, and the slides were so bound up that the leg would barely move.


After moving the slides, and doing a better job measuring, I managed to get this working...sort of anyway. Still alot of binding, and I am pretty sure that I will need to cut down the center leg a bit to make this fit properly. I need to find about 1/8 of an inch somewhere in there and get rid of it to get this thing gliding.

Disassemble

Well it was raining today, so no painting. I haven't gone to hardware store for materials to build the feet, so It was on to the legs.
After a few quick notes from Andy again, It was clear that I needed to take apart my A&A frame.


The 2 large support pieces that run the length of the frame is where I will be mounting the drawer slides to guide the center foot. I cut these drawer slides following Alex Kung's tutorial. I thought I would only need 2 but it turns out I will need 4. Mounting 2 on each side. You will notice that the motor cutouts are also in the way, so I will be modifing the frame a bit to rotate the motors to the top center.


Alex mentioned that he would explain how he modified his drawer slides to stop the bearings from falling out, but I couldn't find it in his tutorial. Here is my solution circled in red, you can see that I made a few small cuts on the slide and then bent the stub down to block the bearings from falling out.

cheating...

ok, It has sunk in how much time I have left to get something working if I want to get to CIV...so commence the cheating.

Dome is looking good. From this distance atleast.


Nothing is going to fall off under normal conditions, but there is a few pieces of tape and superglue in use here.


Darth Will, and Victor provided a few files to fake led solutions for logic displays. I grabbed up some transparencies and made a few.

Oh, here is a closer look at my dome which hasn't been seen before. You won't be able to count the imperfections that I have been ignoring. Again, anyone that etches a dome and makes it look really nice.. has my respect.


in other news.. dome electronics are coming along. I need to come up with a few PSI housings, and get a few more LED's. I have a pretty good blue, but my red, yellow, and green are really dim and not acceptable.

I also spent some time on the Carl's electronics pic flashers just to find out that the crystal is probably bad. Waiting on some information from the group before I seek an alternate solution.

Dome ring sanded and primered. Tape and Paint tommorow.. and repeat on Friday to finish dome.
