Sorry if this is a silly question, or already asked and I missed it, but I was looking at the ERP page, and admiring the engineering that went into it. one thing that I'm confused about. On the servo list it says it uses HS-225BB x 2 (wheels) servos and I looked at servo city at their list of servos that can and cannot be modified for continuous rotation, and they say the HS 225BB is not modifiable, but a similar servo HS-225MG is able to be modified. What's the difference between a BB and an MG servo?

Nylon vs Metal gears.
This is a useful list on their website for the modification difficulties: http://servocity.com/html/rotation_modification_difficul.html (http://servocity.com/html/rotation_modification_difficul.html)
I'm kind of curious why Admin chose to use Mini servos for the wheels (unless that was a typo).
I personally recommend the HS-425BB servos if standard size fits well. They're super smooth, low-priced, and a 360-mod difficulty of 1 (basically take out a little plastic piece). Very good for basic wheels.

Ok, thanks, I'll go with the HS-425BB servos. I don't plan building a ninja robot anytime soon, lol. I just mostly want a good platformto experiment with my blackfin camera. I think I'll be fine as long as the cat doesn't attack. Thanks
