Two-Finger RG2 Grippers

On Robot is bringing its technology to North America to provide manufacturers with more user-friendly, safe and flexible grippers for collaborative robots (cobots). On Robot’s two-finger RG2 grippers—available in both single and dual versions—mount on the arms of cobots without any external wires; for robots that have infinite rotation of the last joint, this enables unprecedented flexibility and productivity, according to the company. The RG2 grippers can be easily programmed directly from the same interface as the robot, and the gripper can be modified without previous programming experience, making them suitable for collaborative robot users.

“User-friendly robot arms need user-friendly grippers, and until RG2, the ease-of-use and flexibility required just wasn’t available,” said Torben Ekvall, On Robot CEO. “Most traditional grippers work by using compressed air, which takes up a lot of space, is energy-intensive and is far too complicated for many users. On Robot’s RG2 is an electronic solution that is easy to mount, is very flexible and can be modified by an operator on the factory floor without the assistance of an engineer. This ease-of-use will help speed development for an increasing number of manufacturers’ applications.”

Unique features of the RG2 gripper ideally meet the needs of cobot users and include:

• Simple and intuitive programming: RG2 lets operators easily choose what they need the gripper to do and the gripper responds with motion as flexible as the cobot itself.
• Angle mounting: From 0° to 180° in 30° steps, in both the single- and dual-gripper setup, the gripper ensures great flexibility and adaptability for comprehensive tasks.
• Customizable fingertips: The gripper fingers support the use of customized fingertips, which can be designed by end users to fit production requirements.
• Assisted center-of-gravity calculation: Users enter the value of the payload and the robot calculates the rest, making programming easier, enhancing overall productivity and improving safety by enabling more accurate robot arm movements.
• Continuous grip indication: The gripper can discern any lost or deliberately removed object.
• Automatic Tool Center Point (TCP) calculation: Automatic calculation of how the robot arm moves around the calculated TCP of an object, depending on the position in which the gripper is mounted, for easier programming and use.
