In order to fully comprehend the working and uses of our project we have included to following as a guideline for operations concerning the Mechanical Hand - Human Interface.

Electrode Placement

Outer Arm

Inner Arm

One grounding electrode is placed on a bony area of the arm, usually the back of the elbow.  Only one grounding electrode is needed for both sets of sensors.

Connecting Electrodes to EMG

These electrode snaps are connected to the electrodes on a human forearm and then attached to the EMG Circuit through the Shielded Cable

Connecting EMG to Micro-controller

The EMG is connected to the micro-controller through the Transducer card, discussed in the Electrical Section.  This card is inserted into the the Bus I/O slot on the mother board.  This card then interfaces with the input card, at Port A.  The output card is placed in Port B.

Transducer Tuning

Connecting Micro-controller to Mechanical Hand

The output card, in slot B of the micro-controller, is connected to a 9 pin male plug.  This plug is the connected to a shielded cable which also connected to the Mechanical Hand
