Gripper Enables Higher Payload on Cobots

On Robot’s RG6 is designed to be a flexible and energy-efficient gripper that is easy to program and install on cobots handling objects of various sizes. It is a bigger and stronger version of the company’s RG2 gripper, with a higher payload than other two-finger collaborative grippers.

The higher adjustable force (25 to 120 N) enables three times higher payload (6 to 8 kg or 13.2 to 17.6 lbs) and wider stroke (160 mm or 6.3"), ideal for automating the movement of delicate or heavy objects in applications such as pick-and-place, CNC, machine tending, packaging and palletizing, and assembly.

The gripper has no external wires, and the end joint can rotate infinitely, making it as flexible and dexterous as the robotic arm itself. It uses electricity instead of compressed air, which saves space and energy, in addition to making it easy to use.

Compatible with all Universal Robots cobot arms, the RG6, which mounts the arm with factory-installed safety shields, is said to be fast and easy to install, enabling operators to modify assembly on the shop floor without the assistance of an engineer.

When programming the RG6, operators choose exactly what they need the gripper to do, and it responds in flexible motion. It also features customizable fingertips to fit production requirements, dual gripper support without extra wiring, assisted center-of-gravity calculation based on the weight of the payload, automatic tool centerpoint calculations that determine how the robot arm moves around depending on how the gripper is mounted, and continuous grip indication enabling the gripper to discern lost or deliberately removed objects.
