I started building Zoe at the bottom and worked my way up, so the photos show the drive section. HOWEVER, Zoe is modular and she was build in several sections. These sections are illustrated at WWW.ZoeTheRobot.Net.
Zoe's Drive section also holds her batteries. Batteries are heavy, and I wanted them mounted as low to the ground as possible. The next section up contains connections, fuses and switches for the batteries and it's called the POWER SECTION.
