The central tower of the telepresence robot is where the interactive features are attached: arms, screens and cameras can all attach to this central hub and connect down into the base of the robot where all of the processors, batteries and other miscellaneous electronics are housed. We separated electronics from interactive parts of the robot for increased system stability. One of the problems with the robot's predecessor was that it would often tip over because much of the weight was placed in the "head" of the robot. In this version stability (both literal and in software) is key.
