Hey guys, long time since I've been around. Just getting to fooling around with my EZBv4. Those are pretty harsh terms of marking a thread as a question! "Don't ask too many!" What's up with that?
But, to my question. I finally made the adapter plate to get the EZB onto my RoboPhilo frame, and now I'm wondering what and how to power everything. I found the thread about power supplies: http://www.ez-robot.com/Community/Forum/Thread?threadId=8369 which had a really helpful datasheet: http://www.ez-robot.com/Tutorials/Files/EZ-Bv4%20Datasheet.pdf, but I'm wondering about power protection.
Normally, when I'm working with DC it's in a vehicle or a rack and there is plenty of room for ATC fuses and fuse holders. There's not so much room in the RoboPhilo, and I don't think that would fit very well. What kinds of protections are available for robots this size? I don't think it would be a good idea to run the bot without one, though it seems the original controller didn't have any kind of fuse to it.
The RoboPhilo is a 24 DoF humanoid robot using old school analog servos, which I hear draw +-200ma of current. Most of the servos are SV4032's, and here's the product page: http://shop.robobrothers.com/product.sc?productId=4. There are a couple of SV4140s: http://shop.robobrothers.com/product.sc?productId=8
Hope this gives you more ideas and direction.

The polyswitch is electrical and when activated will open the circuit and then close the circuit when the initial cause is no longer present, after a timing interval of a few seconds or days depending on the type of polyswitch installed.
