i will be adding a second link to the lower hole on the L bracket for more support. this is merely the prototype to see how it will work. there is play in the “tibia” but once that other ball link is in place its really sturdy.
i can 'and probably will be removing the hex standoff and replacing it with a tube and the new SES Ground Contact Sensor too.
the great thing about this design is the servos ‘especially the tibia’ doesn’t require as much movement as other designs. obviously this will be confirmed once i have it running. at the moment the leg weighs 9oz and i have populated it with HS485’s.
Does the 15° bracket (ASB-17) provide any additional functionality, or is it purely aesthetics? I noticed Frank used a more complex set of levers in his design. I like your simplified version better. I’m building one too. lol
thanks your comment jim. simple is best. his designs are very well made but not very modifiable!
yes Alan the coxa is tight only allowing 25º of movement to the left. and full range on the right. the ASB17 is just purely aesthetics but it will allow the body to sit slightly higher. i like the way it tilts the femur and tibia servos.
Ha! Inline hex too, interesting… I missed that in my lurking. Hey, is that femur you have there about 3" pivot to pivot? The Phoneix is 3" even. I’m trying it with the Phoenix femur.
You are seeing a limit because of the short “C” bracket. The long “C”, or the HBKR chassis would free it up.
Remember you may need to install a 44mm brace between the servos at the bottom for stabillity and to stop the servos from forcing there self away from each other. you will see what i mean if you dont.
i think it may be more mechanically efficient. i will only know once i build the whole thing, then i can really test it. 8)
April fools… i wouldn’t dream of it.
wutha! 
LOL
