[FINALES] Wireless controlled robotic arm

 5. FINALES

5.1  FUTURE ENHANCEMENT

           The concept principle and methodology that we have used to develop our project can be further developed to build large scale project. It can be advanced further to use in remote sensing approach. Such as in remote sensing in geology, GIS, agriculture etc. similarly it can be developed further and may use in bomb disposal, it can be used in antiterrorist campaign.

The project we have developed is just a prototype. It can be further enhanced by using advanced components and some more concepts. Some of the possible applicable areas might be at:

·                     Remote Sensing

·                     Geographical information system

·                     More easier and helpful tool for disabled and elderly people

·                     Telemedicine in more effective way

·                     Bomb disposal

·                     Radioactive areas

·                     Rural areas development like crop monitoring, irrigation etc

5.2         PROBLEM ENCOUNTERED

During the project period we faced many problems. The main problem was the unavailability of the preferred components in the market. During the hardware design we didn’t get special type of cutter to make accurate shape of the arm parts. Unavailability of XBee adapter to mount XBee on the board makes us difficult because of shorter pin gap (i.e. 2mm). Another problem in our execution part was the complications of the RF module interfacing. We experienced the obligations of the wireless communication media as it seemed simple in theory but immensely tough in real time application.  Mechanical parts that we required for our project were not available that made us compulsion to make ourselves so the accuracy couldn’t meet the desired. Gripper consists of gear and making the gear by ourselves was the worthless almost. So, we maintained it by other way which couldn’t function by best way. So our robot is quiet not satisfactory in the mechanical parts. Load shedding problem created an obstacle for the full time work.

5.4            LIMITATIONS

               We believe no machine is perfectly efficient and our system is no exception to it. There are certain identified and unidentified limitations existing in our system. Hardware, software and environmental inefficiencies have forced us to summarize our limitations as follows:

·         Our Robot is controlled only up to 100 meters on favorable environment.

·         We are using dc geared motors so there is problem on speed control of robot base.

·         Since we are using Joystick (made by ourselves) for the control of Robotic arm the movement is not accurate and precise

5.5                   RESULT

           Wireless controlled Robotic arm will be controlled remotely. For remote control, control signals will be sent using radio frequency. We have developed remote controller device that will have capacity to transmit control signals remotely to the receiver installed in the Robot. The robot will respond to the signal accordingly as desired. The arm will be able to move or rotate as instructed by end user. The camera installed on the chassis of the robot transmits sequence of video frames to the receiver.

5.6            DISCUSSION AND CONCLUSION

              This project is aimed for the fulfillment of our final year curriculum of BE Electronics and Communication. It was completed with great devotion and dedication. During the course of development we did what we could do. We gave our ultimate effort for the completion of this project. We accepted the challenges as an opportunity to explore new ways to do simple things in different ways. This project is basically a prototype of an actual field applicable robotic arm which could actually help in rural development and assisting human life effectively.

            Finally, we are hopeful our prototype would work as desired and give expected outcomes, and we believe our concept would be further utilized in advance step to develop rural areas and upgrading the lifestyle of disabled people.
