Robot gripper with an active roller

Machine, Science & engineering

UNMET NEED

Industries are increasingly using robots to speed up the sorting and distribution of goods and consumables, as well as to improve worker safety. These robots are designed to assist workers in performing their tasks more efficiently and safely. For picking up objects, the robots are equipped with a multi-axis arm and a motorized gripper. However, in some industrial settings, objects and materials that need to be handled can vary in size, shape, and weight and may be located in cluttered or hard-to-reach spaces. Despite the availability of a large number of robotic grippers, very few are capable of picking up efficiently flat or soft objects such as books or textile.

TECHNOLOGY OVERVIEW

The Robotics Laboratory at Laval University has pioneered a groundbreaking gripper technology featuring two fingers driven by a Hoekens mechanism, which optimizes both the aperture and gripping efficacy. One of the fingers is equipped with an active rolling surface with a replaceable coating, while the other offers optional nails.

  • The technology offers a parallel grip for secure grasping of objects through the Hoekens mechanism, which ensures both fingers maintain their grip.
  • It also offers a picking grip, which enables efficient grasping of flat objects by using either the roller or nails to scoop the object back into the gripper.
  • Moreover, the technology’s active surface enables it to grasp soft objects even without access to their edges, by creating a fold.

Additionally, this gripper can be easily adapted to a wide range of serial robots (UR, Kuka, Yaskawa, Kinova, etc.), and requires an additional electronic system to operate the roller and the finger, which seamlessly integrates into factory environments.

Lastly, the gripper has been designed for ease of manufacturing and is optimized for efficient production.
