Just a heads up that we have 6 new brackets coming soon to the Servo Erector Set.
ARF-02 is a foot for the Scout and Lynx209 bipeds.
ASB-14 is used for the low profile rotation axis.
ASB-15 is a dual ASB-04 which allows two servos to be joined end to end.
ASB-16 is a short “C” bracket combined with an ASB-04.
ASB-17 is the 15 degree ASB-04 for the ARF-02 part.
ASB-18 is like the ASB-06 but without the bend. Allows two ASB-04’s to be combined at a 90 degree offset.
Curse you, Jim! How could you come out with new brackets just after I finally finished designing my custom humanoid?!?!
Wait a sec… More brackets = cooler biped = waist rotation = new ideas! Bless you, Jim!
Any idea as to when they’ll be available?
Any pics of them?
I was hoping for someting like the ASB-06 without the bend - that’s what’s holding the upper arms together on my biped right now… It works, but is not as clean as it could be.
Jim, have you had any thoughts on / plans for a way to get hip or ankle joint brackets that combine two servos on different but interscting axes? It’s do-able now with a combinatio for the existing brackets but I think it could be done in a more compact way. Some of the robot one competitors have really clever two-axis joints at the ankles and hips that make the legs more compact without sacrificing any degrees of freedom.
No images yet. We should have all of them in 3 weeks. Available for sale prolly first of next year realistically. We are going as fast as possible on this stuff. It’s quite addictive creating them.
I can relate to that. I love desining robot parts like the head I recently designed. Now I just need to get my hands on some cash! I should be ready once my kids are out of day care. That will save me $1200 a month!
Yes, but nothing concrete. The low profile rotation axis will add the 3rd DOF to the hip and only add .375" to the height of the bot. That will help… But I have not yet been inspired as to how to do the X/Y in a low profile bracket.
Hrm… That threaded insert reminds me of the dual horned servos made by Kondo for their KHR-1’s. Perhaps this could be used in the same way?
Obviously, I can’t answer your question about whether or not they fit, but maybe one could remove them?
Oh, btw, I’m stealing your idea for using stronger servos for the ankles.
It’ll be helpfull not only for weight bearing, but also for jumping, dodging, running, etc.
Sure! Two ways to do it. You can replace the 5995’s bottom plate with the one that does not have the threaded hole (it’s included), or you can drill out the ASB-04 to accept it. The ball bearings will mount right to the 5995 and everything fits perfectly.
Fantastic! These servos are pricy but well worth the investment in my opinion considering the aplication they will be used for. Thanks Jim for the image showing the options.
P.S. Is that an aluminum servo horn I see? It looks very nice!
Hey Nick! It’s a new product promised from Hitec. It just happend to fit our brackets perfectly. We are also designing one that will use 2-56 hardware instead of the metric hardware the Hitec ones use. I don’t have a date when they will be available.
The hubs are in, the balls are ordered, the metal forms are here, the gears will be here next week. Then Beth and I will do the assembly and use instructions, and put them on the website. I’d say you will be able to get them in about 6 months… Joking, prolly Jan 30th… I’m sorry it’s taken so long. My fabricator was dragging his feet for a long time. But parts have been flooding in here all week. Finally!
