Ashraful Alam Shimul, a Master's student of the Department of Applied Physics, Electronics & Communication Engineering of Islamic University made this office file carrier Robot. He used locally collected simple and cheap electrical and mechanical parts to make it. He claimed that this Robot can bear various official files or letters from one place to another successfully. It will even be able to bear heavy tools if the technology is improved, he also said. As part of M.Sc thesis work he got the success under the supervision of the department teacher Khalilur Rahaman. He also got assitance from Bangladesh University of Engineering & Technology (BUET) students Morshed, Siam and Palash, says a press release.

Shimul, about his Robot, says that it is needed initially to make a visible line on the floor, which is deeper in color than other parts of the floor. The Robot moves one place to another successfully following this particular line. He says, structurally, the Robot has two major part electrical part and mechanical part. The electrical part includes four units: Censor unit which works as eye of the Robot, controller unit or the brain of the Robot made of a micro-processor which controls all other units, calling unit which is made of a voice type calling bell and which calls some one to give or take files or letters and power supply unit which supplies power to the Robot.

In the Mechanical part units include DC Motor which provides necessary force to the wheels of the Robot, Gear box which controls excess power taken from the DC motor and Main body of the Robot which is made of smooth and transparent crystal sheet which includes structure and file box of the Robot.

The inventor of the office file carrier Robot, Shimul claimed that the mechanical response of the Robot is very much effective though it has been built without following the modern technology of Robot building.
