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.
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: http://i531.photobucket.com/albums/dd355/innerbreed/100_2027.jpg
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.
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)
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.
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.
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.
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
