Patent number: 4632632Abstract: A low cost, programmable industrial robot is provided which incorporates a simplified construction with relatively sophisticated movement capability. Preferably, the robot is pneumatically operated. The robot construction includes a series of simplified structures for both calibrating ease and providing relatively versatile movement in view of the overall product cost. The device provides four adjustable axes of movement and multiple axes mounting for an end effector. In the preferred embodiment, a rotary actuator provides rotational movement for the robot. Rotary movement is adjustable and a simplified structure is included for providing repeatable intermediate stop positions for the work arm of the device. An improved rotary manifold for a rotary actuator provides a conduit for pneumatically powering the remaining robot movement functions. Those functions include vertical reciprocal movement, horizontal reciprocal movement and rotary movement of a gripper device or some other end effector.Type: GrantFiled: August 30, 1983Date of Patent: December 30, 1986Assignee: Automation Equipment CompanyInventor: Raymond J.

Patent number: 4606694Abstract: Load skidding vehicles commonly include a grapple assembly (42) which under load conditions can pivot rearwardly about its support point (52) resulting in disproportionate loading of the rear wheels and consequently instability of the vehicle. A connecting member (62) is pivotally attached between the grapple (42) and a hydraulic cylinder (74) which is attached to the skidder (2). Operation of the hydraulic cylinder (74) causes the grapple (42) to rotate about its support pivot (52). The hydraulic cylinder (74) may be locked causing the grapple (42) to be locked in relation to the boom assembly (26). During load hauling operations this mechanism is used to lock the load in a position near the vehicle resulting in increased stability. The mechanism is also of use in positioning the grapple assembly (42) with respect to the load prior to grasping it.Type: GrantFiled: January 5, 1983Date of Patent: August 19, 1986Assignee: Caterpillar Inc.Inventors: Thomas C. Meisel, Jr., Lyle E. York

Patent number: 4600357Abstract: A gripper assembly for a robotic arm includes two opposing elements displaced by means of a worm gear arrangement for grasping an object positioned therebetween. The worm gear is driven by a rotary drive motor with a torsion spring coupling the drive motor shaft to the worm. First and second shaft encoders are respectively mounted to the drive motor shaft and the worm shaft. First and second pairs of optical sensors respectively coupled to the first and second shaft encoders detect the angular speed and displacement of the drive motor shaft and the worm. With the torsion constant of the spring known, the force applied by the gripper assembly which is proportional to the angular displacement of the worm may be accurately determined and controlled. In addition, the size of the object grasped by the gripper assembly may be determined. By comparing these operating parameters with selected values, the gripper assembly may be precisely controlled such as by means of a microcomputer.Type: GrantFiled: February 21, 1984Date of Patent: July 15, 1986Assignee: Heath CompanyInventor: Russell G.
