View Full Version : Series Elastic Actuators

I have been reading about SEA's the last few days, just wondering if anyone here has used or designed/built one? Seems like data other than peoples thesis is hard to come by. Should I be searching under a different term than series elastic actuator?

So I couldn't really find much other than PhD papers... So I decided to make one, check out my blog post if you are interested. Pretty cool devices, and not that hard to rough something up!

Hey very cool, might have to try making one myself. Was thinking of a way to control servos relative to pressure/force on it. Only idea I had was to measure the servos' current but that doesn't give me direction of force.

Thanks for your researching!

I was amazed how well it actually worked considering the parts I used were very inexpensive. The servo-saver makes the whole thing pretty easy, and if you wanted to I'm sure you could experiment with different springs to have a more sensitive device. I found once I added the white lever the device had a nice holding force but gave in once I put some pressure on it.

If you make one and run into any problems let me know, I had fun working on it and wouldn't mind duplicating your setup to assist.
