Problems solved by technology

However, working in a common working area is also accompanied by great dangers for personnel
A commercially available industrial robot can have a large number of moving parts and can all develop a speed of motion such that there is a great risk of injury to a person in the event of a collision with a person

Embodiment Construction

[0030] In the examples described below, the described components of the robot arrangement and the described steps of the method each represent an individual, mutually independently observed feature of the invention, which also respectively improve the invention independently of each other and thus also These are to be considered as part of the invention individually or in combinations other than those shown. Furthermore, the described embodiments can also be supplemented by other features of the invention that have already been described.

[0031] figure 1 A top view of a working area 10 is shown, in which a person 12 and a robot 14 are located. The robot arm 16 of the robot 14 is swiveled during the working process by a drive (not shown) of the robot 14 . The person 12 also has to remain in the working area 10 during the working process, for example, because it passes workpieces to the robot arm 16 or takes workpieces from the robot arm. Therefore, the robot 14 and the per...

Abstract

The invention relates to a method for controlling a robot (14), which is designed to be operated in a working mode, in which a part (16) of the robot (14) is moved at a speed at which there is a risk of injury to a person (12), the working mode being deactivated if a safety device (18) detects that the person (12) has entered an action region (60) of the displaceable part (16). The aim is to make close cooperation possible between the person (12) and the robot (14). A sensor unit (20) determines a position and a posture of the person (12) while the person (12) is outside the action region (60) of the part (16). A prediction unit (26) determines an action region (58) of the person (12). A collision monitoring unit (28) monitors whether the two action regions (58, 60) overlap (62). The robot (14) can optionally be switched from the working mode into a safety mode.

Description

technical field [0001] The invention relates to a robot which is designed to be able to operate in an operating mode in which parts of the robot move at a speed in which there is a risk of injury for persons if they collide with the parts. The robot has a safety device which deactivates the operating mode if a person is located in the active range of the movable part. The invention is also associated with a method for controlling a robot. A robot can be used, for example, in a handling system. Background technique [0002] Manipulation systems and similar modern workplaces are increasingly demanding situations in production where effective cooperation between humans and robots is required. In general, the closer this cooperation can be achieved, the more efficient it will be. However, working in a common working area also entails considerable risks for personnel. Commercially available industrial robots can have a large number of moving parts and can all develop a speed ...
