For Archie's joints Harmonic drives are employed in order to decreasing the size of the design and increasing the efficiency of the Robot.  Each joint is controller individually and can provide a high performance motion control.  All the joints are connected to central control unit using a customized high speed network.  Archie's central controller unit is called Spinal system which is designed to control the whole robot as well as maintaining the balance of the robot.  For the balance in the robot, the "Spinal system" uses the feedback from the joints and the data from an inertial measurement unit (IMU).  Electronic design and implementation of Archie is done by Ahmad Byagowi as his PhD thesis required project.

University system: A university system is a set of multiple, affiliated universities and colleges that are usually geographically distributed.  Typically, all member universities in a university system share a common component among all of their various names.  Usually, all member universities of a university system are governed by a system-wide governing body, such as a board of trustees or a board of regents.  In fact, university systems are so common in post-World War II United States that most states have one or two state university systems under which many of their publicly funded universities are aligned, both in name and in governance.  Additionally, for-profit universities, such as DeVry University, often have multiple campuses which share the same name; these may be, but are not always, described as a university system (not necessarily accurately, see below).
