Schilling Robotics RigMaster

The RigMaster is a five-function, rate-controlled, heavylift grabber arm that can be mounted on a wide range of subsea ROVs


It is engineered for the strength needed to withstand the industry’s harsh and repetitive needs day after day. The grabber arm can be used to grasp and lift heavy objects or to anchor the ROV by clamping the gripper around a structural member at the work site It is constructed to be reliable in situations that require rugged operation.

The arm’s linear actuators have been life tested under full load for 250,000 cycles with minimal wear. The actuators use the latest cap seal technology to minimize leakage, ensuring long life and minimal maintenance. Its construction is of primarily titanium for structural strength, light weight, corrosion resistance, and extraordinary resistance to damage from collisions.

RigMaster manipulators have a proven track record of reliability in the world’s most demanding subsea environments
