The VERSABALL® Research Kit is suitable for testing and evaluation of real-world applications in advance of our full commercial product release. Performance specs can be found on page 5 of the User Manual. Research Kits are not intended for full time deployment in industrial applications, as the performance specs cannot yet be guaranteed and we are unable to support ongoing head replacement at this time.

How Does a VERSABALL® Gripper work?
Once an object is gripped, the vacuum inside the gripper seals so the object can be transferred without additional expenditure of energy. Holding forces on an object are generated through a combination of three separate mechanisms as shown below. Shown on the left, friction forces from pinching are the most common. These forces develop during the small volume contraction that occurs when the gripper is vacuum-hardened. In the center, entrapment or capture of the object can occur if the gripper can wrap around some geometric feature. This mechanism is less common, but can increase holding force dramatically when it occurs. Finally on the right, a vacuum-suction force can develop in the sealed gap that forms between the gripper and a smooth object. This mechanism is also less common, but can provide dramatic increases in holding force as well.
When it’s time to release the object, pressurized air is applied to soften the gripper once again. Read all about how to program and use a VERSABALL® Gripper in Section 8 of the User Manual.
