Robot safety devices
A short overview:
| Name | Figure | Note |
|---|---|---|
| Emergency-Stop |  Robot Teach Pendant with Emergency Stop | Because an emergency-stop has to be always approachable it is also a part of the control panel. Activating an emergency-stop leads to an immediately stop of all drives of the robot. Stopp-categorie 0 |
| Robot Safety-cell |  Robot Safety Cell | Burst proof Plexiglas pane also protects from accidentally thrown work pieces. The contact for verifying the door of the safety cell is normally integrated within the emergency-loop |
| Hold-to-run or Deadman switch |  Deadman switch located at the back of the teach pendant | Only important for the programming mode or manual mode (safety cell can be opened): The drives of the robots can only be activated if this switch is in mid-position. |
| Test mode with reduced speed |  Robot safety device - move with reduced speed | For certain applications, like a test run of a program, the robot should move in slow motion. A selector switch is usually integrated within the hand-hold programming device. |
| Pressure sensitive matt |  Robot Safety Device - pressure sensitive matt | Supervising the danger area. |
| Torque monitoring | Collision detection via torque monitoring | |
| Electric skin | no pic | Contact with the housing is detected. |
Note: What is a free-turning device of a robot?
With the free-turning device, it is possible to move the robot axes by muscle power for example to free a trapped person. For this purpose, the control system must be shut down before.
Choice of different modes
For certain applications it is necessary to drive the robot in a reduced speed. Examples would be the teach-in programming, if you are close to the robot or the test run of a new program. Each robot, even with simple control, therefore, has at least two modes, namely, HAND 'and' AUTO '.
