Previous Projects

Developed 3D mathmatical models using MATLAB and data collected from literature inorder to predict and controll ratcheting response of the following metals: 1020 Stainless Steel Alloy, SA333, 42CrMo, and SS304. Writing of technical report documenting objectives, methods, conclusions, and applications.

Designed a mobile robot using the Arduino Uno R3. With limited electronic components and common house hold items for the mechanical components the robot is able to complete three tasks. In the first task the robot is to be manually controlled to complete a course. In the second task the robot is to complete the course autonomously. In the third task the robot is to be able to complete a course while avoiding obstacles. The designed robot is able to complete all the task in the following times 7 seconds, 4 seconds, and 8 seconds, respectively. Did basic wiring and soldering on electronic components. Using USART to debug program. Writing of techinical report to document the design process and decisions. Videos are shown here.

Designed a Solar Tracker using the Arduino Uno R3. The Solar Tracker is able to track light in the azimuth and altitude with only two LDR sensors, as well as one stepper motor and servo motor. The mechanical components of the project is made using common house hold items(cardboards, tape, and glue). Did basic wiring and soldering on electronic components. Use of USART to debug program. Writing of technical report to document the design process, and results. Demonstration can be seen here.

Worked in a team of 6 to design a shock absorber for a bicycle. Using the transmissibility ratio to determine the value of spring and damping coefficient, as well as the mass and frequency of the absorber. Matlab was used to aid in simulation and calculation.

Worked in team of 6 to design a single stage gear box. Was responsible for the design of the shaft. Did force analysis, deflection, static and dynamic load analysis, and critical speed analysis. Matlab was used to aid in calculation. Was also responsible for bearing selection. Did research on use of couplers.

Worked in a team of 4 to designed a four bar mechanism with a coupler point that traces a figure 8 path. Used MatLab to aid in design through simulations and to conduct error analysis. Gained full mark within the project.
