Telescoping Vertical Arm for Glove Box Robot

      Disclosed is a device that will be used in a glove box that
will reduce the overall glove box volume while maintaining the same
robot work envelope.  An IBM designed robot incorporating this device
will be used to handle hazardous material inside the glove box.

      Reducing the volume of a glove box has several advantages.  The
cost to construct the glove is less with a smaller volume.  Cleaning
the inside of the glove is easier when the glove box surface area is
less.  The glove box has an inert atmosphere (argon or nitrogen, 0%
humidity).  This atmosphere is easier to maintain with a smaller
volume.  With reduced size, less hazardous waste will be generated
when the robot and glove box are decommissioned.

      This telescoping arm is composed of three sections.  Linear
bearings are mounted between these sections.  One outside section is
fixed to another joint of the robot.  The other outside section moves
through the full travel.  The motor with a sprocket is mounted on one
end of the center section.  An idler shaft is mounted on the opposite
end of the center section.  A timing belt (or gear belt) runs between
the motor and the idler shaft.  This timing belt is fixed at a point
on each of the outside sections.  When the motor turns the belt, the
two outside sections move in opposite directions relative to each
other.  The arm is shortest (collapsed) when all three sections are
in line.  B...
