Educational Robot, SCARA, 4-Axis


DAC #437 Educational Robot, SCARA

This economical, yet fully functional, industrial-quality, 4-axis robot is ideal for training and research in many educational applications.

With a payload lifting capacity of up to 5.5 pounds (2.5Kg.), and a tip speed of 8 in./sec. (0.2 meter/sec.), its performance and abilities approach that of industrial devices. A pneumatic, vacuum or stepper motor gripper can be provided. An electric gripper is standard.

The PC-based controller uses PID control algorithms and can support two additional axes excluding the gripper. Programming is done using specially developed, PC-based, Robot Programming Language, or using C for low level modules.

Teaching can be achieved through off-line programming, joint space programming and coordinate space programming. The device is capable of point-to-point and continuous path movements.

Whether used as a stand-alone training device, or in combination with other DAC automation-related training products in a complete manufacturing system, this device will help make training in this fundamental industrial technology more informative, productive and realistic.
