Disclosed is a robot which is compact in structure and may be movable in a
large working range, wherein move members 1, 1 may be moved by drive
devices 4, 4 respectively along a straight line and in parallel with each
other, the drive devices 4, 4 including motors 40, 40 respectively which
are individually controlled by a control device 9, so that the move
members 1, 1 may be moved at a different speed and may be stopped at
different relative positions. The move members 1, 1 are connected to a
work holder 3 by means of arms 2, 2, the arms having one end pivotally
connected to the move members 1, 1 at the pivots 10, 10 thereof
respectively, the arms 2, 2 having the opposite end pivotally connected
to the work holder 3 at the pivots 30, 30 thereof respectively. The work
holder 3 may hold an optional jig and may be moved in a horizontal plane
and in a vertical plane enabling the jig to work in the working plane.
