STAR is a capstone project with the goal of designing an autonomous stair climbing robot for the College of Engineering at Ohio Northern University. This robot will be designed to climb stairs as fast as possible while also balancing an object overhead. The advanced technical knowledge needed to build this robot provides an excellent showcase of the skills which can be acquired through the duration of the Ohio Northern Engineering Program. In order to begin the design process the project’s client, Dr. Vemuru provided the constraints for the project. The constraints include size, weight, speed, cost, and aesthetics. Some of the constraints are taken as metrics for the STAR project and additional metrics were created by the group members as a tool to compare different designs. While researching competitive designs, four different alternatives were analyzed in order to determine the appropriate design. This was done through a weighted decision matrix. The four alternative designs that were compared include a tri-wheel, tank track, 6-legged robot, and rover. For the balancing aspect of the project two designs have been considered and we would like to potentially implement both if time allows. Those two designs consist of a mechanical design and an electronic design. Our current plan is to implement the mechanical balancing mechanism with the first robot. The STAR capstone project does not have any negative effects on the environment. There are no hazardous materials or parts that could not be recycled or reused. Other design considerations include economic, safety and welfare, social, ethical, manufacturability, and global. The estimated budget for the project has been submitted and approved for our first robot. The main focus is to get one robot functioning properly before considering constructing another. We determined what parts were needed and searched around to find adequate components at a reasonable cost to save money.
