The following list identifies the significant risks that integrators must
consider. Please note that there may be other significant hazards from
certain robotic devices.
Finger is clamped between joint 4 and joint 5;
Sharp edges and sharp spots on the tool or the tool
connector may cause damage to human skin;
The obstacles sharp edges and sharp spots, which is closed
by the robot trajectory, may be dangerous to human skin;
Sprains or fractures due to impact between the robot
payload and a solid surface;
Consequences due to loosening of bolts used to secure
robotic arms or tools;
Items fall off the tool. For example, due to insufficient
clamping or accidentally power down;
Operating error due to different emergency stop button
allocation and types.
2.4 Safety Operations
2.4.1 Emergency Stop
Emergency stop takes precedence over all the other robot control
operations. Pressing emergency stop will cause all controlled hazards to
stop, removing the motor power from the robot drive. It will remain in
effect until reset manually.
Activate emergency stop button to immediately stop the robot from any
motion. The user must perform a restoration procedure, resetting the
emergency stop button and pressing the "Power On" button on
demonstrator, to resume normal operation. Emergency stop shall not be
used as a risk reduction measure, but as a secondary protective device.
Emergency stop must not be used for normal program stop; constantly
pressing may result in additional unnecessary wear on the robot.
