8.3 Explain the robot costing

8.3.1 Discuss briefly about robot costing

–      One of the factors to consider is the cost involved in the use of robots. 

–      whether the purchase of the robot will result in a change in efficiency, economy and practicality. 

–      Companies need to make a detailed study on the cost when planning the use of robots in the production 

–      To make sure production can cover the cost of using the system.

 

a. Initial Robot cost

•       Also called direct cost

•       Divided into 5:

–      Robot cost - the cost of the actuator, manipulator, controller, power source and programming systems used by the robot

–      End Effectors- it may be the standard that can be purchased at open market or made ​​specifically for certain jobs or tasks. The components in the sensor tip and gripper or other hardware. Typically the cost of the end effector is 3-10% of basic cost robot.

–      The cost of additional equipment, it involves a larger memory capacity for
stored-program, computer, monitor, a special panel for the robot controller. box
teach (teach pendent), a special cable to the interface (Interfacing) between all
components and others.

–      Training costs for operators and programmers who will use the robot
for operating or production work.

–      The cost of support tools to develop a robot cell- for example:

          –      Conveyors

          –      Safety equipments

          –      Other automation components needed

  

b. Installation cost

•       Installation work is usually done after the analysis, planning and preparation is made, on the estimated time of the arrival of the robot

•       The next action is to give enough time to test all the equipment when the robot arrives later.

•       At that point, make sure all equipments received, especially those related to the robot assembly must conform to the standards set for the robot.

•       If not, it will cause problems in the future.

•       Costs during the installation robot:

•       Site preparation, including preparation of the floor and support structure for supporting equipment.

•       Installation of basic amenities and communication for robot software for example, wiring and equipment for electrical power will be used during robot operation.

•       Interfaces for pneumatic line connections, hydraulic and electrical equipment from the robot to support.

•       Robot assembly process and equipment support.

•       Transfer and storage processes equipments

•       Before installation of the components in the robot system is made, the performance of equipment should be considered.

•       Rigid supervision needs to be done and to correct any problems before work is commenced.

•       Among the critical examination to be considered during installation are:
 

•       Make sure the belting in the robot can maintain the speed when carrying a load and can be adjusted accurately.        

•       Make sure the gripper or tool holder can work properly.        

•       Make sure that the 'jig' and related equipment can be used correctly
