Okay I think my target is to eventually build something like Biped Nick - any assembly guides coming out for him. What I love about Lynxmotion is all the helpful details
We still consider Biped Pete a do-it-yourself project. There are assembly guides for the arms, legs, and the torso, but we just haven’t taken the necessary time to wrap it all up in a tidy tutorial. We do have a pretty good tutorial for the BRAT, and the concept scales up just fine.

Thanks for the feedback - What I was the most curious about is looking at Biped Nick, I was wondering how the electronic are mounted. My assumption is that the upper torso section you would connect the SES Electronics Carrier to say the Aluminum Dual Inline Multi-Purpose Servo Bracket Single Pack to house the shoulder Servos. Or the U Channel which I see in the BRAT assembly the one with 3 sections where you could attach servo horn, although I didn’t see that as a something you can purchase separately on the site. I have some ideas and I plan on downloading and playing around with the 3D objects.
What I think I may start out with is ordering a Brat Kit with the upgraded Hitec serovs - BRAT Servo Upgrade Pack - 645. This would give me a start with servo set that could expand to a full Humanoid. I would also have the SSC-32 and Sequencer software. Looking to get the BotBoard with Basic Atom down the road as well
I have to say I really like the website, how much information you get. The projects actually seem very feasible to put together - but I think safe bet is to start with Brat and work my way up.
Just to let you know, the 3" U-Channel is available separately.

That was quick, and now I see my mistake, I was looking at the brackets. Thanks for the post
For a full humanoid, you would be better off with the more powerful digital 5645. That’s what Jim used for Pete and Nick. Sure it’s more money, but you want it to work well.
Ditto. hitec 5645s are perfect servos for a full humanoid. The weight of all that aluminum would be too much for 645s. You want smooth movements, don’t you?
Sounds like I should get the Brat Kit with no servos, then just buy the 5645s 6 pack servo deal. Hmm, or maybe the 5955 - it’s double, but man that would be a wicked strong Brat, the 5955s are listed as compatible for SES
No, don’t buy the 5955’s, there has been problems with that one and the 5995 (that was discontinued), the 5955 has still less problems than the other one, but it already died by over heating (the woltage is rated 4-6 now). You’d be better off with the 5990 or -80.
mmm, I sense that there’s gonna be a question : the 90 as 3 titanium gears wich are stronger than the metal ones in the 80.

As was brought up previously in a different servo thread: At the scales and applications we’re dealing with, the primary benefit to titanium gears over the generic “metal” type is less a question of strength than it is of weight (a savings of a fraction of an ounce). If your servos encounter enough force to break the teeth of either metal or titanium gears in the reduction stages, chances are pretty good that the plastic case that contains them and holds their axles in place will fail before the gears do.
Thanks for the advice on the 5990TG. I also was checking around on Robosavvy forum. Looks like Matt Bauer is using those in Rooks Pawn III. I have to assume he’s done some heavy research on them. This Brat is gonna be expensive
but worth it, espacialy when you see the whole biped you’ll have
