Sensors have been installed on the motor which allow the computer to track movement and speed.  An old ball-mouse has been disassembled and its sensors mounted on wires, and these sensors were placed at the open end of the drive motors.  An optical interruptor is attached to the end of the motors' driveshafts, so the "mouse" reports movement on the x and y axes of the mouse when the left and right wheelmotors turn.  The "mouse" is DB9 serial, and is seen by the computer as a serial accessory rather than as an actual Human Interface Device to move a mouse cursor (this would not be the case if a USB serial adaptor were used).  The serial port corresponding to this "mouse" (which uses standard serial mouse protocol to report "movement") is '''/dev/odometry''' as set in udev config files.

An LCD monitor has been mounted permanently as the seatback.  '''The ON/OFF switch for the monitor and its built-in amplified speaker-system is a pushbutton switch on the left (as you look at it) "shoulder" of the robot.  Sometimes the speakers enter a feedback loop and power to the screen should be shut off to cease this irritation.''' The monitor is an [[Inexio]] touchscreen but we have not implemented the touchscreen function yet.

A robot arm made of mostly aluminum and animated by air-cylinders was fitted to the robot, but few electronic valves and no air compressor or tank have been acquired.  Someone will have to invest time and energy to get the arm to do more than make the thing look more menacing.  As of 11/15/2010 the arm was removed to make the robot more wieldy/less unwieldy.
