I have a few robotics projects in mind (pan/tilt for android phone, robot arm, hexapod/scorpion, biped, hand, etc) and I'd like to find some good servos close to the crux of price and performance. I'd like to find something that is common, well supported, and well documented. I'm looking for "regular sized" and "mini" (micro?) recommendations so that I can get familiar with the right sized servo for the job. My intended controllers are arduino mega/ADK's, so I'd prefer to stick to PWM controlled servos since there are plenty of PWM outputs on those (~48, right?)
I didn't realize there was quite the variation in size until I started looking on Thingiverse http://www.thingiverse.com/thing:38159 and saw that there were different sized "9G" servos. Before I saw that I assumed there were 2 or 3 standard sizes (physical dimensions) and the other differences were in power output and interface (serial vs PWM).
I know that the Bioloid kits are pretty common (I see them every time I Google), and that people are developing interface boards for Arduinos, but I think that most of the stuff I will build will wind up being custom. If I start with a kit, are Bioloids a good place to start?
