Kinematics
The relationship between the motion of the endpoint of a robot and the
motion of the joints. For a Cartesian Robot this is a set of simple linear
functions (linear tracks that may be arranged in X, Y, Z directions), for a
revolute topology (joints that rotate) however, the kinematics are much
more complicated involving complicated combinations of trigonometry
functions. The kinematics of an arm is normally split into forward and
inverse solutions.
L
Ladle Gripper
An end-effector, which acts as a scoop. It is commonly used to scoop up
liquids, transfer it to a mold and pour the liquid into the mold. Common for
handling molten metal under hazardous conditions. See
Laser
Acronym for Light Amplification by Stimulated Emission of Radiation. A
device that produces a coherent monochromatic beam of light which is
extremely narrow and focused but still within the visible light spectrum.
This is commonly used as a non-contact sensor for robots. Robotic
applications include: distance finding, identifying accurate locations,
surface mapping, bar code scanning, cutting, welding etc.
Lifting Bracket
A lifting fixture factory-shipped installed on the manipulator. It contains
hoist rings used for lifting by a chain sling. The lifting bracket is not rated
for lifting by forklift. It must be lifted by chain sling only.
Limit Switch
Prevents the manipulator from moving past overrun positions. Provided
for the S, L, and U axes.
Linear Interpolated Motion
Is a method of path interpolation that commands the movement of the
robot by moving each joint in a coordinated motion so that all axis arrive to
the position at the same time. The path of the Tool Control Point (TCP) is
predictable and will be linear.
Linear Motion Type
Is a method of path interpolation that commands the movement of the
robot by moving each joint in a coordinated motion so that all axis arrive to
the position at the same time. The path of the Tool Control Point (TCP) is
predictable and will be linear.
Link
A rigid part of a manipulator, which connects adjacent joints.
Links
The static material, which connects the joints of an arm together. Thereby
a kinematical chain is formed. In a human body, the links are the bones.
Load Cycle Time
A manufacturing or assembly line process term, which describes the
complete time to unload the last work piece and load the next one.
