Schilling Robotics Unveils Dexterous Grabber Manipulator

Schilling Robotics LLC introduced a breakthrough manipulator arm, the ATLAS 7R Dexterous Grabber. This new, seven-function dexterous grabber offers an elbow joint that replaces the “extend-retract” maneuver of a five-function grabber by adding two degrees of freedom, making it a premium option for performing complex tasks. The extended range of motion allows the gripper to access targets from acute angles.

In addition to dexterity, its lift-to-weight ratio is among the strongest in the industry. ATLAS weighs only 5 kg more than Schilling’s current RigMaster grabber, yet lifts 250 kg of weight at its full extension of 65 inches, compared to 54 inches for the RigMaster. The additional joints can withstand extreme loads through an overpressure protection feature in the valve manifold that allows the joints to absorb forces in two additional planes.

The grabber has been undergoing field trials since December, which have proven that Schilling’s attention to kinematics, finite element analysis, and reliability are paying huge dividends in customer productivity.

“The enhancements to customer productivity are proven in extremely heavy-lift work encountered during anchor handling operations,” said Tim Ranstrom, manipulator product manager for Schilling Robotics. “ATLAS has the strength and dexterity to manipulate mooring connectors, where other manipulators would either be unable to lift the load or fail due to overstress. It is also optimized for construction work such as manipulating saws and grinders and to position the tools accurately and repeatedly. Its dexterity makes it very effective at rigging operations, where its slender profile allows unobstructed views of the tooling during complex and precise movements.”

The ATLAS will make its debut at the Offshore Technology Conference, May 4-7, 2009, in Houston, TX.
