Robot Arm
An industrial robot can be dissected into five major components – a robotic arm, controller, drives, end effector, and sensors. Robot arm is one of the important part of industrial robot especially in industrial automation. Robot arm can change the human for
The robotic arm component of an industrial robot usually contains six axes of motion, although some models have more or less depending on the application they were designed for. The robotic arm makes up the majority of the system and is often the focal point. The robotic arm houses several other components including wiring, cables, and drives. Typically, the larger the robotic arm, the higher the maximum allowable payload.
How to made arm robot?
Shoulder is the stationary based where the component is attach. The engineer first make the design on the computer using CAD (Computer Aided Design) to get very intelligent. Then to make the based they use computer guided press to bench and welding. Next painting the casing using powder paint and electrostatic process to guarantee ferro coat so the casing will like a magnet. After that making a user diagram to illustrate how the arm robot will move.
Then create the robot arm hand, first making the gripper which is function is to grasp and carry the object. The material used to cover it is an aluminum. Also they assembly the printed circuit board (PCB) that will control the robotic arm movement. Them they assemble the electrical component to the base. And other component like gear, shaft.In the arm shoulder system, they install system of pulleys, which consist 2 plastic wheels in several axel and rubber belt running between them. The belt in the wheel rotate the wheel and make the robotic arm move. Each robotic arm is programmed to act several task, and move like humans arm. They installed the cable to the electrical based to make move the shoulder. After that they assembly and screw the entire arm to the base.
They linked the wire from circuit board on the base to the every motor in the shoulder, but the wire must be bounch together. After all the wire installed correctly, they test the wheel and gear to make sure they move. Then they set up the gripper, where the shaft and the gear system operate it. Turning the gear one way opened it, and turning the gear in another way will closed it. After there’s running well, they assemble it to the shoulder arm. Plugin the motor to the circuit board.
The board is look like mother board on our PC, all of the component install on it from the circuit until the controller like the processor that control anything connected to the circuit.
Most robot is programmed, so we can easily change the program depend the use of that robot. For the employee robot is the ideal workers because they don’t need rest, laugh, sick, food and drink and can minimize the cost significantly for the long term. And the productivity is constant.
