By a News Reporter-Staff News Editor at Robotics & Machine Learning Daily News Daily News-From Alexandria, Virginia, NewsRx jour nalists report that a patent by the inventors Garcia, Carles Calafell (Munich, D E), Rokahr, Tim (Munich, DE), Spenninger, Andreas (Karlsfeld, DE), filed on May 7, 2020, was published online on June 4, 2024. The patent's assignee for patent number 11999056 is Franka Emika GmbH (Munich, G ermany). News editors obtained the following quote from the background information suppli ed by the inventors: "In particular for robots for use in the field of human-rob ot collaboration (HRC), it is imperative for safety reasons to provide an emerge ncy stop or braking device in the event of malfunctions or in the event of a sud den failure of the power supply, which is designed to stop the robot arm as quic kly as possible in order to prevent injuries to an operator of the robot system or to prevent the object manipulated by the robot arm in the course of the activ ity to be performed by it or the robot arm itself from being damaged. Such an em ergency stop can also be caused directly by the user himself, for example by act uating an emergency switch. "For example, a wide variety of embodiments of braking devices are known for joi nted-arm robots, with the aid of which the movement of the robot arm can be brou ght to an abrupt stop, or at least to a very rapid stop within a defined period of time. "In European Patent No. 3 045 273, for example, a braking mechanism has been pro posed in which a friction ring is mounted coaxially with the motor shaft, with w hich a pin of a locking device cooperates by radially engaging the pin in the fr iction ring in an emergency. Due to the fact that the friction ring is rotatable relative to the motor shaft under a defined frictional engagement, a low brakin g deceleration of the rotational movement is realized when the radial pin engage s.
