ROBOT ARM

The term robot originates from the Czech word robota, which roughly translates as "compelled labor." The most widely manufactured robot is the robotic arm. A standard robotic arm consists of seven metallic segments joined by six joints. The computer controls the robot by rotating individual step motors connected to each joint (larger arms often utilize hydraulics or pneumatics). An industrial robot with six joints bears a striking resemblance to a human arm, featuring the equivalent of a shoulder, an elbow, and a wrist. Typically, the shoulder is anchored to a stationary base structure rather than to a movable body. This type of robot boasts six degrees of freedom, enabling it to pivot in six distinct directions. Robotic arms are capable of performing a broad range of tasks extending far beyond welding, depending on the tools attached to the end of their arms. Recent advancements in end-of-arm tools include; 3D printing tool heads, heating devices for molding and bending materials, and suction devices for folding sheet metal.
