Precautions for robots

1. Provide safety measures for end effector (gripper, etc.)
• enD effectors must be DesigneD anD manufactureD so that they cause no hazarDs (such as a loose
worKPiece or loaD) even if Power (electricity, air Pressure, etc.) is shut off or Power fluctuations
OCCUR.
• If ThE ObjECT gRIPPED by ThE EnD EffECTOR MIghT POSSIbly fly Off OR DROP, ThEn PROvIDE aPPROPRIaTE
