Some people I know designed a bunch of electromechanical actuators, meant for things like industrial automation, aircraft, and mining. The extent they were able to improve on such basic mechanical things was somewhat absurd
I’m surprised to hear this. I thought electromechanical actuators were a slow moving technology. Could you expand on this? A link to public information would suffice.
Yes, most of those clever mechanical mechanisms were invented 150 to 60 years ago, but there are a few newer ones, eg the Thompson Coupling from 1999. Also, the specific torque of planetary gears has increased from improvements in materials, lubrication, and modeling. There’s also been increased usage of designs that aren’t technically new but weren’t practical in the past, like roller pinions.
The actuators I mentioned were developed by a private community I was invited to because of my blog. I don’t have permission to post the designs, but I can list some relevant properties if you’re interested.
