1. Work Done

The robot in the video performs Machine Tending. This involves:

• Loading: Picking up a raw workpiece (such as a metal blank) and placing it into a CNC machine.

• Unloading: Removing the finished part once the machining cycle is complete.

• Part Transfer: Moving the finished piece to a conveyor belt or a storage bin for the next stage of production.

2. Type of Automation

This is a form of Programmable (or Flexible) Automation.

Unlike "fixed" automation, which is built for one specific task, this robot can be reprogrammed to handle different part shapes, sizes, and machine types. It is designed for high-speed, repetitive tasks where consistency and 24/7 operation are required to keep the CNC machines running without human intervention.

3. Joints Used

The M-20iB/25 is a 6-axis articulated robot. It uses six revolute (rotational) joints, often labeled J1 through J6:

• Base (J1): Allows the entire arm to rotate horizontally.

• Shoulder (J2): Moves the lower arm forward and backward.

• Elbow (J3): Extends or retracts the upper arm.

• Wrist (J4, J5, J6): Three compact joints that allow the robot to pitch, roll, and yaw, giving it the dexterity to orient parts at complex angles.

4. Grippers Used

In machine tending applications, this robot typically uses Pneumatic (Air-powered) Grippers. Common variations include:

• Parallel Grippers: Two fingers that close in a straight line to pinch the part.

• Dual-Grippers: Often used in CNC tending so the robot can hold a raw part in one hand and the finished part in the other, minimizing the time the machine door stays open.

• Vacuum Grippers: Used if the parts are flat or have smooth surfaces that are difficult to "pinch."
