PROJECT MANAGEMENT
To increase efficiency of the project as a whole, Team Tiny Tools devised a division of tasks based on the qualifications and interests of each team member. The project is broken down into separate tasks and each task is assigned to an individual. The chart illustrating how the project is divided is provided below.
Austin Carr - Motor Research and Development
Jim Cicero - Base and Carriage Development
Venu Padala - Microcontroller Research and Development

BUDGET
As the guidelines illustrate, Team Tiny Tools has been allotted a project budget of $600. In addition to the project budget, $200 has also been given to cover travel expenses to the Aerotech facility. Development and parts costs for such a system have been found to be very expensive. Because Aerotech has a large interest in the development of the linear stage, an additional parts budget has been given to the team, covering such items as motors, microcontrollers and position sensors.
Below is a list of each of the components of the Linear Stage and the prices of each of the components.

COMMUNICATION AND COORDINATION WITH SPONSOR
Team Tiny Tools’ sponsor is Aerotech, Inc., based out of Pittsburgh, PA. They design and manufacture products ranging from components such as bearing, motors, and actuators to complete linear motion and lift stages. Stephen J. Ludwick, Ph.D. is an engineering manager at Aerotech and is the liaison between Aerotech and Team Tiny Tools.
Communication between Aerotech and Team Tiny Tools is accomplished through weekly conference calls, weekly email memorandums, and periodic visits of either party to the Aerotech facilities or to the Penn State University campus. This web page has also been developed by Team Tiny Tools and will be updated periodically to include developments and milestones of the design project. Austin Carr is responsible for the weekly memorandum. Jim Cicero will be in charge of web page updates. Weekly conference calls will be conducted between Team Tiny Tools and Aerotech.
