I just purchase a biped torso and tried assembling it with HS-485 servos, but was unable to get them to fit. I just read “HS485-HB tight fit in SES brackets…”, so it appears this is also a problem for the biped torso. Is there any way to get these servos to fit in the torso, or am I going to have to buy different servos?
If I have to buy different servos, what maximum dimensions should I be looking for to be sure they will fit the torso?
Which part are you referring to? Part numbers would be helpful.
BT-01 - Humanoid Biped Torso
BT-02 - Lynx 209 Biped Torso
BT-03 - Biped Scout Torso
How specifically are they not fitting?
i believe he is meaning the BT-01 - Humanoid Biped Torso. i can already tell you the 485’s will fit the other two.
i know that the 485’s have a slightly longer case. or are there other dimensions that are larger than say the 645’s?
anyway. one way to reduce the length of the casing is to remove the back plate, sand it down from the inside edge and then place it back on again.
looking at the assembly guides im having trouble seeing what parts would make the assembly not compatible with the 485’s?

looks to be a fair bit of room there.
Sorry, Humanoid Biped Torso, BT-01 here: lynxmotion.com/p-437-humanoi … ervos.aspx
There isn’t enough room for the ‘head’ servo between the two ‘arm’ servos. The arm servos will fit fine without any head servo in place. I can post a pic later tonight if necessary.
yes again looking at the picture i can see that it does look tight.
seeing that its only one servo that you are having problems with i would either do as iv suggested or just change the servo. if its only for the head i would choose the HS-311 servo.
Yes the problem is the head servo will not fit between the shoulder servos. I guess it’s never been brought up before as most people use more powerful servos for this type of robot. We will update the product info to reflect this. All the other standard sized servos will fit. This problem is specific to the 485.
I figured as much. I’m just using the torso for a couple pan/tilt turrets with airsoft cannons and a pan/tilt camera. I already have the pan/tilts up and running mounted to a rather unattractive and bulky wooden frame, and the HS-485s have more than enough torque for that purpose. Just using the biped torso to clean it up and make it a little more compact (but apparently a bit too compact). Still have to figure out how I’m going to mount the torso to the base rotate, but that’s a separate problem.
