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 '.
