  • Method for configuring an end-of-arm tool for a robotic arm
    Patent number: 8033002
    Abstract: An end-of-arm tool having a workpiece interface tool is attachable to an articulable robotic arm. The end-of-arm tool can be configured by engaging an adjustable modular unit including a swing arm, a cylinder, and a workpiece interface tool to a rail element of the end-of-arm tool. The adjustable modular unit machine-slides in the rail element to a preferred x-axis position, machine-pivots to a preferred angular orientation, and machine-extends along a longitudinal axis of the cylinder to a preferred z-axis position, and machine-rotates to a preferred rotational angle about the z-axis.

  • Reconfigurable end-of-arm tool for robotic arm
    Patent number: 8025277
    Abstract: A configurable end-of-arm tool attachable to an articulable robotic arm is described. The end-of-arm tool comprises a rail element, a machine-adjustable swing arm, a machine-adjustable extendable shaft attached to the swing arm. A machine-adjustable rotator set is attached to the extendable shaft, and a workpiece interface tool is attached to the extendable shaft. The swing arm, the extendable shaft, and the rotator set are machine-adjustable to place the workpiece interface tool at a predetermined position.
