Enable Switch
See
Enabling Device
A manually operated device which when continuously activated, permits
motion. Releasing the device shall stop robot motion and motion of
associated equipment that may present a hazard. (R15.06)
Encoder
A feedback device in the robot Robot arm that provides current position
(and orientation of the arm) data to the Controller. A beam of light passes
through a rotating code disk that contains a precise pattern of opaque and
transparent segments on its surface. Light that is transmitted through the
disk strikes photo-detectors, which convert the light pattern to electrical
signals. See
,
Envelope
Is the range of movement available . This range is determined by the
length of a robot's arm and the design of its axes. Each axis contributes its
own range of motion.
EOAT
See

.
End-effector
An accessory device or tool, specifically designed for attachment to the
robot wrist or tool mounting plate to enable the robot to perform its
intended task. (Examples may include: gripper, spot weld gun, arc weld
gun, spray point gun or any other application tools.) (R15.06)
Endpoint
The nominal commanded position that a Robot will attempt to achieve at
the end of a path of motion. The end of the distal link.
Error
The difference between the actual response of a robot and a command
issued.
Expandability
Being able to add resources to the system, such as memory, larger hard
drive, new I/O card, etc.
External Force Limit
The threshold limit where the robot moves to or retains position, even
when external forces are applied (provided that forces do not exceed
limits that would cause an error).
F
Feedback
The return of information from a Robot or sensor to the processor of the
robot to provide self-correcting control of the Robot.
