be moved. In that case, the base is installed to the rail so that the robot can move from one place to another. For example, a robot can work for a few machine tools, loading and unloading for each machine.
As mentioned earlier, the appendage extending from the base of the robot. The attachment is a robot arm. It can be a linear movable arm, it can be a hinged arm. Articulated arm, also known as articulated arm.
Adjunct manipulator can provide a variety of sports-axis robot. The shaft is connected with the fixed base, which base has been tightened to the rack. This rack can ensure that the robot is in a position to maintain.
Ends of the arm connected to a wrist. The axis of the wrist and wrist flange by additional components, with the flange of the wrist, the robot according to the different users can work in different tools installed on the wrist.
Axis allows the robot manipulator in a certain area implementation. As mentioned earlier, the region known as the robot work unit, and its scale and size of the corresponding robot. When the robot's physical size increases, the size of the unit of work must also increase. Mechanical hand movements by the driver, or drive system control. Drive or shaft drive system allows the movement in the work unit, drive system using electric, hydraulic or pneumatic power. Drive the energy emitted from a variety of mechanical drive into mechanical power. These drives are joined together by a mechanical linkage. The linkage in turn drive the various robot axes. Mechanical linkage from the sprocket body, composed of gears and ball screws. Controller
Robot controller is running in the heart. After the memory controller stores used for the pre-programmed information, control peripherals, to communicate it with the factory computer to make the production of constantly updated.
Controller used to control the manipulator motion and the outer parts of the work unit. Staff can use the box to teach hand-delivery actions programmed into the robot controller. This
information can be stored in the controller's memory for later recall using the device. Robot controller stores all program data. It can store several different programs, and they can be in any program to be edited.
May also request the work unit controller and peripheral devices to communicate. For example, the controller has an input line, the input line can be identified when a mechanical process to complete. When the mechanical cycle is complete, the input line is connected, it will place orders for the controller to the robot manipulator to pick up the processing of finished parts. Then, the robot then picked up a new part and it is placed into the machine, then, the controller send a signal to the machine to get it started operation.
Mechanical manipulation of the drum controller can be constituted, the work place by order of the drum operation. The controller for a very simple robot system. Seen in most of the robot system controller is a very complex device, which reflects the modern electronic science. In other words, they are manipulated by the micro-information processor. These micro-information processors instead of 8 bits, 16 bits of information that is 32-bit processors. This feature allows the controller to run with very good flexibility.
Controller can send electronic signals through the communication line to issue with the mechanical hand signals to communicate with the axis of the robot manipulator and controller, this two-way communication between the location and operation makes the system constantly revised and updated to maintain the state may The controller can also control the robot wrist in the end installed any tools.
There are different controller computers and factory to carry out the task of communication, the communication network will enable the robot to become computer-aided manufacturing (CAM) part of the system.
According to the basic definition, the robot is a multi-function can be re-programmed robot. Therefore, the controller must include some form of memory storage, to micro-processor-based information systems are often associated with solid-state memory
device with the operation. These memory devices can be magnetic bubbles, random access memory device, soft plastic disk or tape. Each memory storage device programming information can be stored for later recall using the. Power source
Source of power to the controller and the robot was powered device, there are two types of robot power supply system. Controller for a class of power is power to run the exchange point, and the other is used to drive the robot axes. For example, if the robot manipulator controlled by a hydraulic or pneumatic device, the control signal is sent to these devices to make the robot movement.
Each robot systems require power to drive the robot, this source of power either by hydraulic power, pneumatic power source, power source can also be provided by electricity, the power source is a unit of work the robot parts and equipment in the total part. When the hydraulic power source with and connected to the base manipulator, hydraulic pressure source to produce the hydraulic fluid, the fluid transport of the control components to the robot, so the robot base rotated around the axis.
Pressure air is fed to the robot, the axis along the track in a straight line, the source can also be connected to such a pneumatic drill, it can provide power for the drill rotation. Under normal circumstances, can be obtained from the factory air supply station for the source and make adjustments, and then enter it in the axis manipulator.
AC motor type can also be a DC-style. Controller sends out pulses of the signal was sent to the robot motors. These pulses provide the necessary instructions for the motor information to enable the robot in the robot base rotation.
The three-axis robot for power systems either require the use of feedback control systems, this system will continue to position data for each axis of feedback to the controller. Each robot system not only need power to start the robot axis, also need power to drive the controller, this dynamic manufacturing environment, the power source can provide. Implementation of end pieces
In most applications where the robot to see implementation of end pieces are connected to the robot wrist flange of a device, end pieces can be used in the production areas of the implementation of many different occasions, for example, it can be used to pick up parts, used for welding, or for painting, the implementation of parts for the robot end system provides the flexibility of the robot must run.
Usually designed to meet the end of the implementation of pieces of the robot users. These components can robot manufacturer or owner of manufacturing robot system. The implementation of the system end the only thing the robot can be a work into another working parts, for example, are available from the cutting machine is connected with the water, which is used in the automotive production line cutting edge. May also request the robot placed the parts to disk, in this simple process, change the end of the implementation of parts of the robot, the robot can be used for other applications, the implementation of end pieces may change, and then the robot programmed allows the system to have high flexibility. Robot Sensor
Although the robot has great ability, but often than not with a little practice, but the workers. For example, workers can find parts that fall to the ground or no parts feeder, but not the sensor, the robot will not get this information in a timely manner using the most sophisticated sensors, the robot is smaller than an experienced worker Therefore, a good robot system design requires many sensor and robot controller using the phase, it was as close as possible operative awareness.
The most frequently used robotics sensors into contact with the non-contact. Contact sensors can be further divided into tactile sensors, force and torque sensors. Tactile or contact sensors can be measured by the drive-side and the actual contact between other objects, micro-switch is a simple tactile sensor, the robot may be angry when the client contact with other objects, the sensor is the robot to stop work and avoid objects between collisions, tell the robot has reached the goal; or when used to measure the size of objects
