Positioner
Drop Delivery
A method of introducing an object to the workplace by gravity. Usually, a
chute or container is so placed that, when work on the part is finished, it
will fall or drop into a chute or onto a conveyor with little or no transport by
the robot.
Dynamics
The study of motion, the forces that cause the motion and the forces due
to motion. The dynamics of a robot arm are very complicated as they
result from the kinematic behavior of all masses within the arm's structure.
The robot arm kinematics are complicated in themselves.
E
Emergency Stop
The operation of a circuit using hardware-based components that
overrides all other robot controls, removes drive power from the robot
actuators, and causes all moving parts to stop. (R15.06)
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 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
or
.
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 Manipulator 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.
