2 Degree Of Freedom Robotic Leg, Oded Tzori, Henry Terrell, Adan Martinez
Mechanical Engineering
Professor Xing, an assistant professor at Cal Poly, proposed the 2 DOF Robotic Leg project for this quarter’s senior project class. The project is to build a robotic leg attached at the hip to a stand, which will be used as a teaching tool and eventually help develop Cal Poly’s very own robotic quadruped. Since this project has multiple uses after its completion, there are multiple customers that it must perform well for: the Cal Poly Mechanical Engineering (ME) Department, the ME Lab instructors, and the students. The Scope of Work (Sections 2 & 3) is composed of 2 main …

Mechanical Engineering
Our group was presented with a challenge to design an automated machine to replace Micro-Vu’s current manual pressing operation. We moved, planned, and scheduled our tasks for the three quarters we will be working on this project by using a Gantt chart. In designing the machine, we generated concepts and used analysis and prototyping to select the most promising ones. Our final design uses a pneumatic press to press the parts, and it includes magazines to hold the parts before pressing, pneumatic actuators to move the parts to and from the pressing location, and a lever to separate the defective …
Design And Implementation Of Eight-Legged Robotic Transporter, Jeremy David Depangher
Design And Implementation Of Eight-Legged Robotic Transporter, Jeremy David Depangher
Master's Theses
This thesis contains the design, manufacturing, and testing of a functional eight-legged robotic transporter based on the concept design laid out in U.S. Patent 7,246,671. The device is intended to achieve three different sequences of motion: regular driving, obstacle climbing, and stair climbing. The prototype was carried through concept design, analysis, selection of materials and components, manufacturing, software development, and final assembly and testing. The device can be assembled under multiple configurations, which harbor certain advantages and disadvantages. The results of the testing encourage the continuation of a second iteration of this concept.

Electro Mechanical Actuator Test Stand For In-Flight Experiments, Michael Koopmans, Catlin Mattheis, Austin Lawrence
Mechanical Engineering
The Prognostic Center of Excellence at NASA Ames is currently researching actuator prognostics, specifically in the application of electro mechanical actuators (EMA’s). Cal Poly ME students Michael Koopmans and Catlin Mattheis and EE student Austin Lawrence have chosen to undertake the task of building a test stand that will be flown in flight while testing EMA’s specific faults. A stand was designed to fit inside a standard 19” rack, take power from the aircraft 3 EMA’s, a computer, data acquisition, and electric magnets switches are powered. A MIL STD 1553 interface is present to allow fault injection. Vibration and temperature …
