Great job with the battery placement! I like it a lot! 
I got another gait working with my scout last night. It looks pretty good but it’s inconsistent with the HS475’s. They have just enough power to move all the joints but with being analog servos, they just don’t hold their position well enough. It creates a mass amount of play and give that can’t aways be seen when using the seq. Sometimes a servo will creep while you are working on the next step and then when you play it, everything seems off because it didn’t have the time to creep into position.
Basically, I’d say Jim was right. The HS-475’s don’t cut it for the scout. They would suffice for a few joints I think but you need almost all digitals and 100+oz in my opinion. So it was worth a shot. I’m going to price out some digitals for it.
My HS475’s will be in the trader section if anyone wants dibs on them.
P.S. My form bender is apparently on backorder now. What a shock.
I picked the Form bender up this morning when I mailed italianguys stuff.
This thing will make life alot easier. 
Except they forgot my Extra dies for it. The one on it if for iron barstock and steel. So it is 1/2" wide with a half circle bending face. I ordered 2 extra dies that are 1/4" and 1/8" wide with a sharp edge for the smaller aluminum.
I’ll have to grind a sharper edge on this one for now.

Well, the short comings of my analog HS-475HB’s on the scout is a bit concerning. I’m wondering if the HS-805BB’s will have the same problems. I was hoping that with enough torque, using analogs wouldn’t be a problem.
But now, I’m not so sure.
What are everyone’s thoughts on this? Do you think the HS-805BB’s will have problems because they are analog servos, even if they are producing 450+ oz torque?
There aren’t any 1/4 digitals with even close to the torque of the 805. Plus the 805 seems to be take alot of Voltage abuse, and just keeps coming back for more. I’m nervous to start cutting up $200 worth of aluminum for a biped that won’t work.
try it
and if it dosn’t work then you can just
use the brackets for somthing else ERRR thats my opinion
but you realy should give ti a chance
cause you can never be too sure 
I see you are using an AtomPro. Are you using the hservo command or a SSC-32? If you are using the hservo command you can try increasing the refresh rate. The faster you refresh analog servos(up to a point) the better they hold their positions. I don’t know if you can adjust the refresh rate on the SSC-32.
They won’t all be universal brackets though. Most will be custom made for the Boped meaning if it doesn’t work, I have an expensive aluminum biped tha tneed digital 1/4 scale servos that don’t exist. I’m just thinking it over before going ahead with it. This is why I bought the scout, to learn from it before attempting something bigger.
And I don’t know if you can adjust the refresh rate on the SSC-32. Currently, I’m not using the Atop Pro28 and BotBoard. Just running the SEQ software straight to the SSC-32.
I’ve done some load testing with a few HS-805’s bolted together and they definitely have the torque. I use 2 servos in a leg pattern with 6" between the joints. At 7.4V they have gobs of power. I mean lots. I don’t know why they seem to have so much more power than my HSR-5995’s since the 5995’s are supposed to be more torque but it sure seems like it.
I’ve started bending some C brackets but I’m deciding on how to make the servo mounts. The SES bracket design allows too much flex in the L parts that the servo mounts to. So I’m molding some servo case bottoms that have a mounting hole in them, like these:
lynxmotion.com/images/Produc … /psh03.jpg
…but for an HS-805BB 1/4 scale servo.
The first batch is setting up now so I’ll post some pics when they are done. Then I just need to make a half frame that bolts to the servo case for mounting the servo to other servos.
sounds cool! cant wait to see em. 8)
I’ll post the in my new thread I’m making. I’ve decided that I don’t feel confortable with my programming abilities enough to get my scout walking, let alone a custom biped. Plus, I’m not totally confident using analog servos on a biped is a good idea.
So I’m going to put this project on the back burner for a bit and pull out another one I’ve been pondering lately. The thread will be in the projects section later tonight.
Good job with the scout.
I understand about the challenges involved with developing anything from scratch. It takes a lot of revisions to get an idea in to a product that works the way you want it to work. New product development can be frustrating, but at the same time, it’s extremely rewarding.
I’m with you about the ED209 from robo cop looks tough. It would make a really cool 1/4 scale bot project.
I think so too. And to have a pile of 1/4 scale servos here next to a pile of aluminum bar stock, makes it tough to not start building it but I just don’t think my programming skills are at that level yet. There is alot of programs and GUI availible for Brat’s and Hexapods but not for A Biped.
So I’m moving on for now and I’ll come back to the idea later. Probably after Jim gets his Mega SES brackets in production.
That’s perfectly fine to put a hold on it. I have done the same thing my self before. Like you said, you have some of the stuff already so when you’re ready to give it another go, you won’t have to get those items.
As for the programming, you could use the sequencer and make it walk. As for A.I. (Artificial Intelligence) you would need to learn how to program.
The best thing to do is to start with step one and work your way up, building on your knowledge and experience. It is very hard to jump in this hobby and try to manufacture a design idea without first learning some basic things.
The brat / scout is a great first step.
" have also tested an HS-805BB to death. Laughing
Results near stall:
4.8 Volts - 260 oz/in Torque, 1.3 Amp Draw
6.0 Volts - 336 oz/in Torque, 1.8 Amp Draw
7.2 Volts - 405 oz/in Torque, 2.0 Amp Draw (Getting warm)
8.4 Volts - 495 oz/in Torque, 2.4 Amp Draw (Overheating)
9.6 Volts - 510+ oz/in Torque, 2.7+ Amp Draw (Overheating big time)
12 Volts - 540+ oz/in Torque, 2.8+ Amp Draw (She’s toast)

Hi,
I was wondering if you get to test the speed of the servo at 60 degree for those setting of voltages.
This is what I have.
60degree
4.8V .20sec
6.0V .15.sec
7.2V .11 sec
No, sorry I didn’t do any speed tests. Just torque near stall. I didn’t test right to stall either because I didn’t want to go through 3 servos before I finished testing.
I’ll hook you up with an order of Servo Case hinges and C Brackets for the HS-805. I sent you a PM.
well u could just do a arm or a hex
these things are gonna be awsome
if u need more support how about using long screws and spacer thru the servo mount and thru the backside
I started a Hex. You can see the complete set of brackets at the end of this thread: lynxmotion.net/viewtopic.php … highlight=
And I wanted to use longer servo case screws and mount something on the bottom but I have searched high and low for screws that thin and that long, and found nothing. They would probably have to be custom made which equals big money.
so are you still going to make a giant scale scout???
I don’t want to sound stupid, and I know this probably isn’t the right place to ask, but how would one go about doing a mold like that? Does it cost thousands of dollars for machinery that you just happen to have, or is it something someone could do in their basement - or somewhere in between?
I’ve got alot of ideas on things I’d like to build, after reviewing my plans I’ve come to the conclusion that I need some sort of CNC mill (at the very least) before I can even come close to recognizing these projects…
Being able to do molds would help with the other 1/2.
