Pick and Place Robot
The 'SCARA' style robot is a four
degree-of-freedom robotic arm that can
be used to pick and place small parts on
a production line. It has been designed
as an appliance; it is totally selfcontained
– the user can plug the power
cord into a standard AC socket and the
unit is operational. In a typical
application it can replace the human
operator in feeding industrial presses
with discrete components. Its low cost
ensures early return on investment and
its modular design with a minimum
number of components promotes
reliability. It can be easily integrated into
automation systems as it provides a
wide range of auxiliary control interfaces for digital and analog inputs, digital outputs,
pneumatics, and stepper control. The programming interface uses PLC style ladder logic
eliminating the need to learn a programming language.
Compact and totally self-contained to minimize installation and redeployment effort and cost
Modular intelligent joint actuators, each powered by a fixed point DSP controller
PLC-style programming interface to minimize training and technical support
Auxiliary control interfaces for system integration and user customization
Optional integrated Web Server to connect the robot to the World Wide Web

Optional user-specified or designed grippers can be
attached at the wrist. Two and three jaw pneumatic
or electrical grippers interfaced with the connectors
at the wrist can be supplied with the arm on request.
