Hanover Fair 2016
At Hanover Fair, Schunk presents the LWA 4P powerball lightweight arm with app-based or manual programming. The arm can be equipped with an electric collision control.
How could one describe a multi-functional handling solution that operates autonomously in a human environment? At Hanover Fair, Schunk presents a mobile, anthropomorphic gripper arm that is designed for intuitive virtual programming and differing successive gripping operations; it can also optionally be equipped to react to collisions.
The overall application is programmed on the basis of ROS. Operation of the powerball lightweight arm and the company’s SVH 5-finger hand is possible with all standard web browsers. For this purpose, Schunk provides an app that can be used on any commercially available smartphone, tablet, or PC. Virtual slide controls and an integrated 3D viewer allow axis-specific programming. Optionally, the arm can be equipped with integrated, electric force control.
To speed up the change between locations, it is possible to save entire procedures for later situation-specific retrieval and adaptation to the particular application scenario. With 24-V technology and integrated electronics, the lightweight arm can be powered by rechargeable batteries and used on mobile platforms. Neither an additional control cabinet nor a PC is required. For communication, the product provides a CANopen interface (CiA 402).
The LWA 4P features a weight/load ratio of 2:1. With a weight of 12 kg (without the base) it can dynamically handle loads of up to 6 kg and has a gripping radius of about 700 mm. Due to the design of the front end, or wrist joint, the arm can also maneuver in confined spaces. Its repeat accuracy of ±0,15 mm provides process stability in demanding measuring and testing tasks.
The design prevents dangerous crushing and shearing movements, which makes the module suitable for use in the direct proximity of people. Since the supply lines for the gripper and tools are completely within the module, there are no interference-prone cables on the peripheral devices. The consistent lightweight construction and torque motors of the latest generation ensure operation of the lightweight arm at an average of 80 W.
At the Hanover Fair from April 25 to 29, the company can be found in hall 2, booth B01.
