Prototype SCARA Robot Arm

The new arrival RDG-SCARA, Rated load 1Kg, can be customized to carry 2-3Kgs.
DEMO_SCARA is belt driven only without harmonic drive 0.3mm positioning precision.
RDG_SCARA is harmonic drive system 0.1mm positioning precision.
Both of the above include a teaching pendant (Demonstrator) which can be used to control, can be purchased separately 400USD or remove from DEMO_SCARA, RDG_SCARA.
SCARA Demonstrator
Can be used to loading and uploading, palletizing, glue dispensing or cutting pins
Main control functions:
5-inch touch screen control, offline programming, teaching programming, path programming using G code
Linear interpolation, circular interpolation, acceleration and deceleration interpolation, multi-axis synchronous rotary interpolation, table coordinate setting Internal CAN bus, external serial communication can be connected to the host computer to control.
With scalable digital input and output signals. The hand opening and speed can be flexibly controlled by PWM, and different end tools such as suction cups can be used. The wrist can be lengthened to any length to form a third-section swivel arm, but the load capacity is correspondingly reduced.
Automatic calibration.
