Abstract:
A robotic gripper mechanism including:a housing; a gripper arm extending from said housing; a finger assembly mounted at a distal end of said arm, said assembly being normally biased to a retracted position; a slide movable in said arm between a first inoperative position relative to said finger assembly and a second operative position; a drive member having at least a first and a second state; and components operated by said drive member and operating on said slide in response to the state of said drive member such that said slide is in said first inoperative position when said drive member is in its first state and in its second operative position when said drive member is in its second state, said slide not influencing the position of said finger assembly when in its first position, and acting on said finger assembly to push it to an extended, operative position when the slide moves from its first to its second position and, to hold the finger assembly in its operative position.
