Abstract
A gripping device with linear actuation for a robotic arm for seizing and gripping Petri dishes and other light items. The gripping device has a support and first and second gripping arms slidably retained relative to the support by guide rods. A motorized drive mechanism actuates the gripping arms through an operating member that acts only on the first gripping arm. Through an interconnection mechanism, movement of the first gripping arm actuates a simultaneous and dependent opposite movement of the second gripping arm so that the gripping arms are movable between a slack position and a clamping position. The operating member acts on the first gripping arm through a resiliently compressible member, the distortion of which is measured to provide a clamping limitation mechanism.
