Automatica 2018 Collaborative grippers and force-torque sensors by OnRobot

OnRobot, the new company formed through the merger of the three international companies On Robot, OptoForce and Perception Robotics, presented its first new products at Automatica 2018. The Gecko Gripper, Polyskin Tactile Gripper, RG2-FT gripper and a technical upgrade of the HEX force-torque sensor product line based on OptoForce technology will open up new applications for collaborative robotics and make implementation easier. OnRobot has positioned itself in the market as provider of collaborative grippers and end-of-arm tooling.

Innovative gripping with gecko and NASA technology

TheGecko Gripper, developed by Perception Robotics, was inspired by nature and uses the same adhesive system for gripping as the feet of a gecko, with millions of fine fibers that adhere to the surface of the workpiece and generate strong van-der-Waals forces. For the Gecko Gripper technology, OnRobot licenses a concept originally developed by the NASA Jet Propulsion Laboratory (JPL) and brought it to market maturity.

This fast-moving solution for handling large, flat objects makes vacuum grippers and their compressed air system unnecessary. In contrast to vacuum grippers, the Gecko Gripper can also handle perforated or porous workpieces such as printed circuit boards without any problems. The gripper is compatible with Universal Robots and Kawasaki robotic arms. The system was among the three finalists of this year's IERA Award for innovation and entrepreneurship, which was awarded at Automatica.

More sensitivity for demanding workpieces

The Polyskin Tactile Gripper also comes from the innovation forge of Perception Robotics. The solution specializes in sensitive gripping: Both fingers can be individually aligned and have integrated tactile sensors at the fingertips. This allows the gripper to precisely measure the condition of the surface of workpieces and align its gripping processes accordingly. These properties take tactile gripping to a whole new level, especially when working with sensitive or irregular workpieces. The Polyskin Tactile Gripper is also compatible with Universal Robots and Kawasaki.

Gripper for precise assembly

OnRobot is launching a variation of its established RG2 gripper, the RG2-FT with integrated force-torque sensors and a proximity sensor, which also accurately detects the condition of objects. The gripper detects the danger of objects slipping off even before it happens, making handling safer — for workers as well as for the workpiece. This gripper model is suitable for use in precision assembly and is compatible with lightweight robots from Universal Robots and KUKA.

Fast installation for sensors

The OnRobot product line for force-torque sensors based on OptoForce HEX technology has received a substantial technical upgrade, making installation and handling of the sensors even easier and faster. Mounting is now up to 30% faster, partly thanks to overload protection integrated in the sensor, which no longer has to be removed and mounted separately when attaching to the robot arm. Furthermore, the weight of the sensor can be reduced by 20%. A new, improved sealing ring also protects the HEX products against dust or water in the environment.
