Important Questions and Answers: Implementation And Robot Economics

Mechanical - Robotics - Implementation And Robot Economics

1.  Different types of material handling operation.

 

Manually operated devices—hand trucks, powered trucks, cranes, monorails and hoists.

 

Automated systems—conveyors,   AGV‘s.

 

Miscellaneous systems—industrial robots, transfer mechanisms, elevators, pipelines, containers, dial indexing tables, etc.

 

2.  Define Gantry Robot?

 

Cartesian coordinate robots with the horizontal member supported at both ends are sometimes called Gantry robots.

 

3.  Give four Applications of AGV.

 

Driverless train operations

 

Storage distribution system

 

Assembly line operation

 

FMS

 

4.  Types of AGV vehicles.

 

Towing vehicles

 

Unit load vehicles

 

Pallet trucks

 

Fork trucks

 

Light load Vehicles

 

Assembly line vehicles.

 

5.  Differentiate palletizing and depalletizing.

 

A palletizer or palletiser is a machine which provides automatic means for stacking cases of goods or products on to a pallet.

 

A depalletizer machine is any machine that can break down a pallet. Usually, a robot is used for this task, although there are some other forms of depalletizer that can also break down pallets and move products from one place to another using simple push bars and conveyor belts.

 

6.  What are the steps to be followed by the company in order to implement robot programs in its operations?  

 

Initial familiarization with the technology

 

Plant survey to identify potential applications

 

Selection of the application

 

Selection of the robot

 

Detailed economic analysis and capital authorization

 

Planning and engineering the installation

 

Installation

 

7.  Typical technical features required for material transfer.

 

Number of axes: 3to 5

 

Control system: limited sequence or point-to-point playback

 

Drive system: pneumatic or hydraulic

 

Programming: manual, powered lead through

 

8.  Different methods of economic analysis.

 

Payback method

 

Equivalent uniform annual cost (EUAC) method

 

Return on investment (ROI) method

 

9.  Define ROI method.

 

The return on investment method determines the rate of return for the proposed project based on the estimated cost and revenues.

 

10. What is EUAC method?

 

Equivalent uniform annual cost (EUAC) method converts all of the present and future investments and cash flows into their equivalent uniform cash flows over the anticipated life of the project.

 

11. Define Deadman switch.

 

A dead man switch is a useful control feature during lead through programming. It is a trigger or toggle switch device generally located on the teach pendant which requires active pressure to be applied tom the devices in order to drive the manipulator.

 

 

12.     What are the general characteristics that make potential robot application technically practical and economically feasible?

 

1)      Hazardous or uncomfortable working conditions

 

2)      Repetitive operations

 

3)      Difficult handling jobs

 

4)      Multicast operation
