Update:
While conducting further testing, I encountered 2 issues with the AI-H200 from FunOSR.
- 2 of the 3 servos that I was delivered for testing/review developed shaking/vibration at rest. This is likely due to a bad encoder/potentiometer. Servos rely on their encoder to determine their position in their travel. If the encoder is giving back incorrect positional feedback, the servo will try to self-correct, sending itself into a feedback loop of shaking. This is not typical with new servos. I’ve seen it with servos after heavy use, but not ones that have only been bench tested. Anecdotally, another user has reported the same issue with a production unit that they purchased from FunOSR.
- The AI-H200’s sound signature has changed after periods of stress testing. Some users have theorized that their low sound signature is due to copious amounts of grease applied to the gears, effectively damping vibration and sound transmission. After a couple hours of use, I think that the grease may have migrated away from the gears, changing the sound signature of the AI-H200. It is not a loud servo at this point, but not as quiet as first measured.
Issue #1 is a big one - reliability is a huge focus point of mine. No one likes troubleshooting a sex toy. It’s the biggest boner killer of all time. Based on this, I’m not going to proceed with testing the AI-H200. I may put together another servo roundup in the future, but this is on hold for now.
