Basically, environments that include uncontrolled heat, moisture, radio waves, magnetism, or electrical circuits, and other robots or human workers..
Robots (mechanized, comp
…uter-controlled operations) are subject to various problems, some functional and some environmental. One is the susceptibility to electronic interference in the command and control circuits. This can be external (magnetic or radio waves) or internal (static and electric grounding problems, or programming errors). Another problem are environmental conditions (heat, moisture) that affect the controls and the moving parts. A third concern is operations around humans, since robots do not always detect human presences. Workers may be injured, or conversely damage robots, by their activities around the machines. (MORE)
