Robot Arm With Seven-Axis Design

Nachi Robot Systems introduces the Presto MR20 robot. The robot arm features a seven-axis design and has a 30-kg. payload capacity. The seven-axis design allows the robot to closely emulate the motion of a human arm, enabling it to perform more complicated work processes in constricted work areas.

 The robot was designed to provide a compact arm and powerful body with a wrist torque that is said to be two times that of comparable-sized robots. The seven-axis design allows the work arm to avoid singularities while providing multiple posture solutions.

 The robot features a horizontal reach of 1,260 mm, a repeatability ± 0.1 mm, a compact base, two 6-mm through-arm pneumatic lines, 18-conductor signal cable, and through-arm support for servo-gripper tooling. The arm is controlled by the company’s AX20 series controller and has a simplified programming solution that uses the primary six axes unless otherwise selected by the programmer.

The robot is said to be ideal for machine tending, material handling and case packing. When coupled with the company’s NV-AX vision system, it can accommodate bin picking and product assembly applications.

    Programming a robot with the same CAM software used for a multi-axis machine tool makes it unnecessary to “teach” the robot by jogging it manually from point to point and recording these point-to-point moves as the robot’s motion commands. Robotmaster is a software package that provides this CAD/CAM-based, off-line programming for robots. It runs fully integrated inside Mastercam CAM software for CNC machine tools.
