here i have used both sections to make two legs. a cross brace has been added to hold it up as i haven’t installed the ankle servos.

Jonny,

You never seem to stop impressing me with your ideas! I love it!

I don’t know bout anyone else, but I am a big fan of the nylon snap rivet fasteners! They seem to work exceptionally well and they help with assembly / disassembly. When four are used, it’s solid as a rock. Because the nylon rivets are softer than metal, it may cause more flex in longer assemblies, but for short assemblies, they are great in my opinion. How’s your long leg design performing with the nylon snap rivets?

yes, well i have used the snap rivets to attach the servos and yes i find they work very well. ideal for fast, easy assembly ideas. i have loads from previous buys and i hardly use them so its nice to have something that helps speed up the building / prototyping stage.

ok a slight improvement on the leg if anyone wishes to adapt this.

if i get time and also the balls to dissemble one of my other projects then i will try and make this a working model but for now im not committing to it. just ideas.

It sure looks awesome! 8)

Great work (as always) Jonny!

I do like your latest leg design,

I might copy parts of this design for Archer myself :wink:
Just using the ASB-15 brackets for the tibia instead.

just a bit of fun.
zenta, have you thought about using the off-set brackets? Also replacing the tibia with ASB-15 would then look like the iron wolf leg.
e.g:

it would make the tibia shorter, there for better IMO.

I see what you mean Jonny, but I’ve not considered using them yet. I’m not sure if Jim has ever considered making some more SES parts that make it possible to make a 2 DOF (with common axis) ankle and hip joint equal to what you’ve seen made with the bioloid brackets and other. It could be made by a pair of ASB-24, ASB-06 (L-bracket, slightly customized), BB-hub and a custom extra wide C-bracket. The L-bracket must be bent a little different, so that the long part get a little longer and the short part gets a little shorter. Mount one ASB-24 with the bottom part mounted to the side part of the other ASB-24 and mount the custom L-bracket to the bottom part of the last ASB-24 so that the long part of the L-bracket are along the other wide side of the servo. Then mount the BB-hub on the L-bracket. Mount the wide C-bracket between the first servo/ASB-24 and the BB-hub.

I believe having a 2 DOF joint sharing the same axis point would make it slightly more compact and the joint more natural in movement, like a human ankle/hip joint.

It’s on my to-do list. I’m interested in seeing any examples anyone cares to share. Thanks in advance. :smiley:

Sounds great Jim! Would be fun to see different suggestions in how to solve that without to many custom parts or to complex parts.

Where is that lexan part from? I like it a lot in this leg design.

yes zenta, you read my mind. it would be great to have a bracket that incorporates this. i think you coxa design for felix was close.

Oh also on the subject: a (long ‘C’ Off-set) bracket would be handy :wink:

oh also i did this a few years ago!!!

ok, Well i should really start listening to my wife more… she has always told me that i cannot help myself when it comes to ideas. saying this i have now taken a quick half hour and populated this robot with its servos. it seems to be holding well. here are some pictures of it standing (posing) under its own weight! 8)

i think this is turning into a project!

any thoughts on a name?

JBG for Jolly Black Giant?

lol…
well its now just waiting for power and programming. its all wired up and ready to go. if i get some time next week ill have a go at firing this little bad boy up. :laughing:

The weight is slightly more than the standard Lynxmotion Scout:

LM Scout= 2lb 4 oz without battery’s.
MY Scout= 2lb 12 oz without battery’s.

now all i need is some big ass guns! lol.
The Knee and Ankle servos hold well due to the springs but i will have to come up with a way of keeping the Hip servos balance too.

Hi Jonny,

Looking good! Where are you planning to place the battery, on top of the ASB-15 bracket? What springs are you using, the same as Lynxmotion sell?

Well, im trying to work out the best place of the battery. Id like to put it under the feet. Im looking at buying two 1600 6v and have one under each foot. The springs are from a assorted box i have of about 20 different types. Ill get the spec once i get home.

I really like the look of this guy! The placement of the springs is nothing short of brilliant. You rock! 8)

thanks Jim. i think the idea here is to get the scout walking using those 645 servos. the springs seem to be the key.
info on the spring:
all i know is the measurements:
extension spring:
8.7x46.8mm
