    Animatronics robot with two arms
    (UMT.Lahore, 2016) Ahsan Javed; Hafiz Abdul Hadi; Muhammad Ishaq; Zain-ul-Abidian
    In these days in the world, there is an increasing need to create robotic or humanoid arms to do different human activities where human actions are difficult to perform or we can say impossible. It may involve pick and drop things, let’s say we want to serve a glass of water to a disabled person or diffuse a bomb, using a wireless control operation. Here we have proposed to build a robotic or humanoid arm controlled by different wireless means. Finally, this arm can avoid the problem such as picking or placing the harmful objects or non-hazardous objects that are far away from us and help to disable patients. The method used in designing and constructing the robotic arm is based on the operational features and characteristics of the microcontroller (Arduino), electronic circuit, servo motors and the programming of servo motors and Arduino microcontroller. The analog voltages received from the sensor (Infrared) are fed into the microcontroller, these analog voltages are converted into digital values using built in Analog to Digital converter of the microcontroller. The analog values from the infrared sensor fed into the Arduino and it is compared with stored reference values then appropriate signals are sent to servo motor 0controller, which actuates the motors to move the arm to the specified coordinates and grip or release the objects.

    Design of overhead water tank
    (UMT.Lahore, 2018) Ahsan Javed; Khizar Nawaz; Asad Jamil; Faiq Amir
    Engineering investigation was carried out to study the water requirement and providing of an overhead water tank to the residents of kotha-pind flats, situated in Lahore to fulfill that demand. Numerous visits were made in order to assess number of residents, water requirement and suitable location selection for constructing an overhead water tank. In addition this project design of overhead water tank will be analyzed using STAAD-pro design software. Storage reservoirs and overhead tank are used to store water, liquid petroleum, petroleum products and similar liquids. The force analysis of the reservoirs or tanks is about the same irrespective of the chemical nature of the product. All tanks are designed as crack free structures to eliminate any leakage. This project gives in brief, the theory behind the design of liquid retaining structure (Elevated rectangular water tank with flat base, beams, columns and appropriate footing) using working stress method. Elements are designed according to ACI standards and other respective guidelines. This report also includes computer subroutines to analyze and design rectangular water tank. The program has been written as Macros in Microsoft word using Visual Basic programming language. In the end, the programs are validated with the results of manual calculation given in (Concrete Structure) book. The present chapter deals with the design of water tanks. Reservoirs below ground level are built normally to store large quantities of water whereas those of overhead type are built for direct distribution by gravity flow and are usually of smaller capacity. The reservoirs can be made with a minimum of M-20 concrete so to provide not only strength but also higher density to prevent leakage. A well-graded aggregate with water cement ratio is less than 0.5 is desired for making impervious concrete. Mild or high yield strength steel reinforcement bars can be used in storage tanks. The permissible stress in the reinforcement is controlled by the strain and the crack widths rather than the strengths. Deformed bars or ribbed steel improve the level of cracking capacity in the concrete. A crack width of 0.1 mm has been accepted as a permissible value in water retaining structures. In view of the complexities and uncertainties associated with the crack widths, a simplified approach through allowable stresses is presented.
