Smart Gripper for Small Collaborative Robots

Providing the right motor for small precision devices can be challenging

With the growth and proliferation of collaborative robots, there has become an increased need for a wide variety of grippers and end effectors in general. One of the more challenging applications is for automated gauging and measurement of small parts. Such a device must provide high-resolution positioning with resolutions as low as 2.5 micrometers that can be continually available to decision-making software in automation applications. This is why New Scale Robotics (NSR), a Division of New Scale Technologies decided to design and manufacture one of their latest grippers.

Built for the smallest collaborative robots, the NSR-PG-10-20, Precision Parallel Gripper, is a mechatronic system that integrates motor, sensors, precision bearing guides, drive, and control electronics, along with embedded firmware for automation, into one device. During the design process, NSR decided that the gripper had to offer plug-and-play integration that could be installed in minutes to Universal Robotics (UR) line of small cobots. The NSR-PG-10-20 offers users the smallest size and mass with the highest precision. All power and control circuitry is located through the robot tool port and slip rings so that no external cable or electronics boards are required. To install the gripper, simply mount it to the UR robot tool flange and connect the single cable to the UR tool I/O port. Motion commands are received through the robot’s 8-pin tool I/O interface. No external wires or separate electronics are needed, which allows for full 360-degree or infinite rotation of the UR robot wrist joint without cable interference.
