| Why Use
Ceramic? |
| Ceramics have superior mechanical,
electrical, and thermal properties ideal for quality components.
the durability of fine ceramics makes it ideal for mechanical
and thermal loads that are abrasive and in chemically harsh
environment. |

| Application Note |
 |
In robotics, an end-effector
is a device or toll connected to the end of a robot
arm. The structure of an end effector (see figure on
the left and right), and the nature of the programming
and hardware that drives it, depends on the intended
task.
A robot arm can accommodate only
certain end-effector task modes without changes to the
ancillary hardware and/or programming. It is not possible
to directly replace a gripper with a screwdriver head,
for example, and expect a favorable result. It is necessary
to change the programming of the robot controller and
use a different set of end-effector motors to facilitate
torque rather than gripping force. Then the gripper
can be replaced with a driver head.
