The mobility base now has a battery pack glued to the bottom of the base itself (major tech companies use hot glue sometimes, too!), and the battery pack powers the servos while the 9v battery powers only the Arduino. Minor issues with one of the servos occasionally not responding but I'm ignoring this for now. Putting Kagaku on the mobility base also makes the whole thing unstable, so again, I'm ignoring for the most part right now and focusing on Kagaku himself, specifically the email portion right now.
