      Accelerometers are cheap.  The new ADXL series from Analog Devices
looks quite useful for robotics applications.  I suggest ordering the
ADXL05SP Sample Pack, for $35.00, from Newark (1-800-367-3573)
or Allied (1-800-433-5700).  The Sample Pack contains two +-5G accelerometers,
two evaluation boards, and data sheets.  Other acceleration ranges are
available, but 5G is probably the most useful for robotics.  Output
from the board is a DC level.  Some assembly required.

     Assembled units are available, including a 3-axis packaged system for
$220.00.  AD will send you data sheets if you call 617-329-4700.
