Progress on the quieter SR2

High frequency motor/gear noise sucks to dampen. Wow.

So I've decided I'm going to go big on this, physically. Nobody really cares if their sex robot is a little bit bigger right? It'll still fit on an Ender 3 print bed (220x220) so the vast majority should be able to print it. I can probably make a split version later.

The first image is a servo mount. You screw the servos into this and then mount it in the case. It sits on top of some mouse pad material to dampen vibration and ...

Baffled Servo Mounts v1 preprint image

This is basically moving each OSR2 servo 10mm inwards, sticking a 25t servo hub on the arm, and extending the arm inside the robot a little. Add baffling around the servo and I'm hoping this shows some decent results in sound dampening. May need to go to something with an internal air gap, but that's a problem for tomorrow me.

Thanks, and upcoming experiments

Just wanted to say thanks, having a few folk chip in over here has been a nice bit of encouragement, so I wanted to share the things I'm working on over the next couple months.... unless a cooler idea appears.

SR2

Currently working on a OSR2 case replacement with a focus on sound reduction. I used a very precise tool (silicone tube held up to my ear) to listen around a servo and noticed that the vast majority of the noise comes from the obvious place, the gearbox near the ...

OSR2+ Modded Servo Arms

I'm making an OSR2+ again, here's some lightly tweaked and upgraded servo arms.

They are slightly stronger and have more quality of life features, but are otherwise identical to the stock parts. No need to upgrade if yours work well for you.

Added access to the horn screws, added internal geometry that adds strength in the most needed areas without relying on infill, doubled up on the slots to allow easier zip tie use, lightly smoothed the parts.

These parts are recreated di...

OSR2 PTFE T-wist Receiver

Required: 350mm+ (14 inches+) of 4mm outer diameter PTFE tubing.

Commonly used with 3d printers, called bowden tube. You probably shouldn't cut your printer's bowden tube for this.
